- Item 0 - Validation for ROS Standing Representatives - ERCOT Staff00:00:55Good morning everyone. This is Susie Clifton with ERCOT. And before
- 00:00:58we get started with today's ROS meeting, I'm just going to quickly go
- 00:01:02over the meeting room efficiencies. Erin has already put this in
- 00:01:05the chat, but we are using the chat in this WebEx only
- 00:01:09meeting to cue for motions or discussion. And then please
- 00:01:14remain on mute until the chair recognizes you.
- 00:01:18And then also as we go to the balloting process, please remember
- 00:01:21to unmute yourself as we approach your segment.
- 00:01:24And then after you have voted, please return to the mute function.
- 00:01:29That'll help us be a little more efficient. If the meeting ends
- 00:01:32for any reason, give us just a few minutes, we'll restart. You should be able
- 00:01:35to log in with the same meeting details and if we are
- 00:01:38unable to use those, we will forward something to the ROTHS listserv.
- 00:01:43And with that, Katie, we are ready to get started.
- 00:01:47And you do have a quorum this morning.
- 00:01:52Thanks, Susie. Thanks for laying it out. Welcome to our
- 00:01:55last ROS meeting of the year. Hope everyone's okay with
- 00:02:00having the WebEx. I figured we all had a lot going on in these
- Item 1 - Antitrust Admonition - Katie Rich00:02:03last few weeks before the holidays. I'll let
- 00:02:07Erin pull up the antitrust and then I'll go over all the alt
- 00:02:10reps that we have.
- 00:02:23Okay. Hopefully everyone had a chance to read it. So for this
- 00:02:27morning, for our alt rep list,
- 00:02:32Nabaraj has Mary Ellen Williams.
- 00:02:36Adam Cochran has Paul Messman.
- 00:02:40Starting at 11am Resme
- 00:02:43with Shell has Shane Thomas. And then Chris Letrick
- 00:02:48with Denton Municipal has Cody Tenorio.
- 00:02:52And then for our proxy, Jennifer Smith
- 00:02:55has given her proxy to Chris Hendricks. And I believe that is
- Item 2 - Agenda Review - Katie Rich00:03:00the entire list. So yeah,
- 00:03:11so let's take a quick peek at what we're we've got
- 00:03:14before us this morning. So I'll give you a TAC update in just a
- 00:03:18second. We are normal two ERCOT
- 00:03:22reports. We have one PGRR before us
- 00:03:25with an IA and then a few language
- 00:03:29review and then
- 00:03:33we have this NPRR1257 that was
- 00:03:37actually already discussed at PDCWG but it's now been formally referred
- 00:03:41to us. We have one item on our tabled
- 00:03:45list and then we start going into our working group
- 00:03:48updates. So OWG, PLWG,
- 00:03:53PDCWG, NDSWG. And then
- 00:03:56we'll do our combo ballot and then finish off with the rest.
- 00:04:00We will spend a few minutes at the end talking about our open
- 00:04:03action items list as we did last month. Just saying if we
- 00:04:07can streamline what's what's on there going into
- 00:04:11the new year. So that's what we got before
- 00:04:14us. And we'll go back up.
- Item 3 - Technical Advisory Committee - TAC - Update - Katie Rich00:04:22And for the TAC update, just a couple of
- 00:04:25items. TAC and the board did approve
- 00:04:30NPRR1247. That was the new economic cost test
- 00:04:35and all of ROS's RRS were approved. And then
- 00:04:39one thing to note is that ERCOT staff
- 00:04:43laid out some proposed revisions to the MDRPOC,
- 00:04:46which is the outage scheduling, and they are
- 00:04:50looking to move to a more probabilistic based approach
- 00:04:55next year for calculating those.
- Item 4 - ERCOT Reports00:05:01All right, looks like the queue is clear. All right,
- 00:05:05so let's move into our ERCOT reports. We'll start with Alex and the operations
- 00:05:09report.
- 00:05:12Morning, Arash. This is Alex Lee from ERCOT. Can you hear me?
- 00:05:15Okay, we can go ahead.
- Item 4.1 - Operations Report - Alex Lee00:05:19All right, thank you. For the month of October,
- 00:05:22the ERCOT peak demand was 72,540
- 00:05:26megawatt, which happened on October 3rd. For our
- 00:05:30HE 1700, this load was 1306
- 00:05:35megawatt, higher than 2023 October peak demand.
- 00:05:39There were three frequency events, all of
- 00:05:42which were due to unit trips. But There were
- 00:05:45no ECRs or RRS that
- 00:05:49were released during the month of October. There were
- 00:05:52no DC TIE curtailments and there were
- 00:05:5649 HRUC commitments,
- 00:05:59a lot of which were related to both either the capacity
- 00:06:03issues or the congestions.
- 00:06:08There were seven OCN operating condition notice that
- 00:06:11were issued, four of which were related to Panhandle.
- 00:06:16Out of four, three were simply notifying that there's a topology
- 00:06:20change that impacts the limit. One relates to the
- 00:06:24outage actually resulting in ERCOT taking
- 00:06:28the manual action for the PNHNDL GTC IROL.
- 00:06:33There were two OCN issues related to
- 00:06:36the extreme hot weather as well as
- 00:06:40a potential capacity shortage reserve.
- 00:06:44And then there were one issued for
- 00:06:47the GTC feed.
- 00:06:52Lastly, there were four advisories issued for
- 00:06:56GMD K-7 or higher, but they had minimal impact in
- 00:06:59terms of real time operations. And the following table
- 00:07:03shows the number of days that each GTC were
- 00:07:08activated and binding in scad.
- 00:07:11With that, I'll open the floor for any questions.
- 00:07:18Thanks, Alex. It looks like the queue is clear,
- 00:07:21but appreciate your update. Thank you.
- 00:07:25Thank you. And that takes us on to the system planning report
- 00:07:28is Ping on. Yes, Katie.
- Item 4.2 - System Planning Report - Ping Yan00:07:31Good morning everyone. So for this month's system
- 00:07:35planning report, I just have a quick heads up.
- 00:07:39So ERCOT plans to bring another update on
- 00:07:43the EHV 765-kV infrastructure plan to
- 00:07:46the December RPG meeting which
- 00:07:50has been rescheduled to December 16th.
- 00:07:53And it will be a WebEx only meeting. So if
- 00:07:57you're interested, please Stay tuned for more discussions on
- 00:08:00the EHV 765-kV
- 00:08:04plan. That's all I have, but I'll be more than happy to take any
- 00:08:08questions.
- 00:08:15Thanks, Ping. It looks like the queue is clear. I appreciate
- 00:08:19that update. Thanks.
- Item 5 - ROS Revision Requests - Vote - Katie Rich00:08:27Okay, that takes us on to item five and we
- 00:08:31have one IA before us for PGRR117.
- 00:08:43Give you guys a second to look at this if you haven't already.
- Item 5.1 - PGRR117, Addition of Resiliency Assessment and Criteria to Reflect PUCT Rule Changes00:09:04You can see the O&M costs there in
- 00:09:08the range and then it looks like this could take effect
- 00:09:11following PUC approval.
- 00:09:15So it is before us today as a voting item.
- 00:09:20Are there any concerns about moving this forward?
- 00:09:33Okay, if not, then we can add this as our
- 00:09:37first item for the. Yep, there we go on
- 00:09:41the combo ballot. Thanks,
- 00:09:44Erin.
- 00:09:56That will take us into language review
- 00:09:59for some fairly new items
- 00:10:03that are coming to us today. So the first, first one is
- Item 5.2 - NOGRR272, Advanced Grid Support Requirements for Inverter-Based ESRs00:10:07NOGRR272, the Advanced
- 00:10:10Grid support requirements for invert based batteries.
- 00:10:15And I, I know that we've already
- 00:10:19had some comments filed by Jupiter
- 00:10:23Power on this one and I think that there were others
- 00:10:27that wanted to speak. So I will let Jupiter
- 00:10:31pop in the queue or Tesla.
- 00:10:36All right. Caitlin, did you want to go through your comments for us?
- 00:10:39Yep. Sorry, can you hear me, Katie? I can.
- 00:10:44Okay. And sorry, I meant to get in the queue immediately but I'm having
- 00:10:47some technical difficulties today.
- 00:10:51First, you know, apologies for getting news in late last yesterday,
- 00:10:56but I think we really just wanted to raise the flag on this one
- 00:11:00and make sure that there is more discussion about
- 00:11:04this proposal. And so to outline my
- 00:11:08comments I would put our concerns into two
- 00:11:11buckets. We have both technical and policy
- 00:11:15concerns with this. NOGRR is written right now on the
- 00:11:18technical side, I understand there's
- 00:11:22an accompanying PGRR that's a little bit more detailed, but really
- 00:11:26on the NOGRR, these read to be performance standards.
- 00:11:30And so as the ESR operator,
- 00:11:33in order to be able to agree that we can do this in
- 00:11:37good faith, right, this would become a compliance standard, we need
- 00:11:41to know that we can comply with what is asked
- 00:11:44for. I think these statements are very vague and we don't
- 00:11:48know what constitutes compliance. So I think as a
- 00:11:52starting step we would need to get language that really gets to the
- 00:11:56specifics of what ERCOT and the ERM
- 00:12:00would consider compliance or not in performance. And then
- 00:12:03once we know that, I think this warrants more, hopefully public
- 00:12:07discussion with the OEMs. So once we know what
- 00:12:11those specific performance standards are,
- 00:12:14we need to know this is something that OEMS can do on
- 00:12:17this fairly aggressive timeline ERCOT laid out,
- 00:12:21I don't think if these are performance standards it would be acceptable to
- 00:12:25hear that it's feasible or that the models from the OEMs
- 00:12:29show that they can do it. I think we really need to know that they
- 00:12:32can do this in performance or operation.
- 00:12:37The second bucket of our concerns is on the policy side.
- 00:12:41I would say we have a big issue with this policy wise
- 00:12:45and with especially the language and the justification.
- 00:12:48This appears to be mandating that not
- 00:12:52even a whole subset of technology but a subset of a subset
- 00:12:55that only ESRs within IBRs pay for something
- 00:13:00that ERCOT asserts has direct commercial benefits to the
- 00:13:04grid. And they note increasing GTC limits. And so
- 00:13:09that appears to be making some kind of causation
- 00:13:12policy cut and then applying it in a way
- 00:13:16that goes just to one subset.
- 00:13:19And so I think on its face that is problematic for the
- 00:13:23competitive market we're used to. I'd love to see it as,
- 00:13:27you know, some kind of incentive or a market based product.
- 00:13:31Understand that might be a longer term on taking but
- 00:13:35we do have a problem with the way it's presented.
- 00:13:37I think at a minimum we'd want to see this tabled for
- 00:13:41more discussion. I have raised my concerns with
- 00:13:45commission staff and so if this is something that needs
- 00:13:49more policy input I would love to see that
- 00:13:53and we narrow language to know what we
- 00:13:57can comply with or not. I think the justification would
- 00:14:01also need to be revised too. That's where you see some
- 00:14:04pretty troubling I think implying that
- 00:14:08causation is the justification for the NOGRR
- 00:14:13and I will leave it at that.
- 00:14:18Thanks Caitlin for laying that out.
- 00:14:22We'll jump to Bob. Caitlin, thank you
- 00:14:25for getting those comments in and actually to let everybody know
- 00:14:29if there'd have been more time with this, you know, with us getting this
- 00:14:32all done, these would probably been larger joint comments.
- 00:14:36So I just wanted to get that out there. I'll probably file
- 00:14:39something in support of what they've got out there. But on the bigger picture
- 00:14:44I'm in the process of writing an NPRR to
- 00:14:48try to address and get the conversation going on
- 00:14:52the policy side of this. It's I've started
- 00:14:55it all but I've ran into a snag and that's try because
- 00:14:59I will have to create a new attachment
- 00:15:02to section 22 and those are
- 00:15:06fill in the blank forms that I don't know how to revise.
- 00:15:10So I've asked for support from client services Corey
- 00:15:15to help me figure that out. So that will be forthcoming
- 00:15:18So I think that tabling this is probably the right path to
- 00:15:22go for now.
- 00:15:26Thanks, Bob. Yeah, certainly no problem with,
- 00:15:29with tabling this and giving everybody more time to discuss.
- 00:15:32I last night got a
- 00:15:36question about sending it to dwg. I'm certainly
- 00:15:40happy with that. To do that. We have had, you know,
- 00:15:43some discussions at IBRWG, so it's
- 00:15:47just a question of what's the will of ROS? Where would you like it to
- 00:15:51go? Would you like it to go to one or the other or both?
- 00:16:11Not seeing anyone in the queue.
- 00:16:15Okay. Julia, you think both would make sense. Okay. And then I know you guys
- 00:16:18have been doing some joint meetings. All right, Chase, thank you.
- 00:16:23Yeah, Caitlin, go ahead. I think both would make
- 00:16:27sense. I was just going to say we're pretty agnostic to where
- 00:16:30this gets referred to. I'd love to see
- 00:16:33more discussion at a higher level too, as we
- 00:16:37get into those policy conversations.
- 00:16:39I'll work with Bob Offline and we'll look to his
- 00:16:43NPRR, but it might make sense to
- 00:16:47be talking about it on the WMS side as well, if we
- 00:16:50are really talking about things that,
- 00:16:54you know, maybe should be a market product or incentive and
- 00:16:58would correlate directly, in ERCOT's
- 00:17:01words, with helping GTC limits.
- 00:17:10Okay, Caitlin, that makes sense, Bob.
- 00:17:14Yeah, that's why I'm writing the NPRR is because
- 00:17:18this being a NOGRR, I wasn't sure how we could get to a
- 00:17:22good, robust stakeholder discussion on
- 00:17:26the policy side of this. And that's why I needed to write the NPRR.
- 00:17:30We can get it over to WMS and others to also take
- 00:17:33a look at that side of it.
- 00:17:41Yeah, that makes perfect sense to me. Bill,
- 00:17:44did you have something to add? Yeah, just a good question for
- 00:17:48Caitlin and Bob. Obviously we've been talking
- 00:17:52about IBR related reliability
- 00:17:56concerns and issues for a while or kind of has raised this issue,
- 00:18:01you know, a year ago at least. But more than that with the NOGRR245
- 00:18:05discussion. So I just, I'm kind of curious, what, what do you guys
- 00:18:09need to see to get comfortable
- 00:18:12with this? Obviously, as we kind
- 00:18:16of move forward in time and continue,
- 00:18:19you know, interconnecting IBRs, the risk just increases.
- 00:18:22So is it just. There's not enough detail in here the,
- 00:18:26the requirements can't be met or you're not really sure how to meet them yet?
- 00:18:29Or are we just going to like rehash all the 245 issues? Again,
- 00:18:32I'm just kind of curious what you guys think needs to change here to
- 00:18:37get reliability requirements in place so that we can address these risks.
- 00:18:52Go ahead, Caitlin. Bob. I think Bob got in
- 00:18:55the queue ahead of me, but I'm happy to speak first. Yeah, go ahead and
- 00:18:58start, Caitlin. So I actually think,
- 00:19:02you know, my understanding is this is probably the opposite approach
- 00:19:06of NOGRR245 and it's TAC a different issue.
- 00:19:11NOGRR245 was a
- 00:19:16ride through requirements and that they were reliability
- 00:19:20requirements specific to the resource.
- 00:19:23This is for grid forming inverters
- 00:19:27and the way this is written makes me think that they are looking at
- 00:19:30the system and looking at things that not just
- 00:19:34could ensure current reliability but help. We're talking
- 00:19:38about increasing stability to the point where
- 00:19:41you could relax or increase GTC limit.
- 00:19:45And to me that is basically saying here is something extra
- 00:19:49the system needs that we would like this
- 00:19:52set of resources to pay for. And so
- 00:19:56I think that's sort of a weird causation link, a weird way
- 00:20:00to do that. Totally agree that a
- 00:20:03product that provides more stability for the grid is a
- 00:20:07good thing and that having grid forming technology for EFRS is a
- 00:20:11great thing. The reference jurisdictions where in
- 00:20:15this case that are using this, pay for this as a product,
- 00:20:19they use sort of RFPs or it's
- 00:20:22state funded. I think in Australia it's a little bit government funded.
- 00:20:26So it's a little bit different in those reference places. It's not mandated.
- 00:20:30We would love to see technology like this come on sooner.
- 00:20:33But I think the difference between this and 245 is 245
- 00:20:37is ride through requirements and it was looking at particular resources and
- 00:20:42the requirements for this resource. This is requirements
- 00:20:46that would increase stability to the point where
- 00:20:49you have now new benefits. And it's looking at
- 00:20:53the system and saying we want these things and the way
- 00:20:56we're going to get these things is by having this set of resources
- 00:21:01be mandated to implement something.
- 00:21:07All right, I'll turn it over to Bob. I'm not
- 00:21:11going to repeat everything that she just said because that was pretty much
- 00:21:14what I was going to say. The only addition I'd make to that is one
- 00:21:17of the, you know, Bill said it's because of more inverters
- 00:21:21are being, you know, connected to the system. I would take that in
- 00:21:25a little different way and look at it as we have a changing
- 00:21:29topology and a changing grid moving forward.
- 00:21:32And it's because of a lot of reasons. There's less thermal,
- 00:21:36there's more renewable, there's more batteries getting on the
- 00:21:40system. So the topology and the generation mix we have
- 00:21:44is all having an effect on this. And like
- 00:21:49Caitlin said, this is an enhancement to the grid that helps
- 00:21:53the overall grid as a whole, regardless of
- 00:21:56who does it. And it's just put on a small group and I'm
- 00:21:59not advocating it go to everybody. That's why I'm advocating a.
- 00:22:02A ancillary service so that those
- 00:22:06that can and will will supply it and ERCOT can say just
- 00:22:10exactly what they need. Because my understanding is you don't really need 100%
- 00:22:14of grid forming inverters on the system to provide that stability.
- 00:22:18There is a subset underneath that. That's where it could be.
- 00:22:28Thanks Bob, I appreciate that additional context. We have
- 00:22:31a couple more in the queue. Alex, go ahead.
- 00:22:35Thank you. I'll be quick. I did just want to note
- 00:22:39that I agree with what's being said. It seems like
- 00:22:42in this case it is a subset and
- 00:22:47there's a. Rather than using the stick,
- 00:22:50wouldn't it be more consistent with the
- 00:22:54way our market works to use the carrot and incentivize
- 00:23:00this optional value service to
- 00:23:05be installed and utilized rather
- 00:23:08than penalizing. You know, Julia has posted in the
- 00:23:11chat you could just have a requirement for all future systems.
- 00:23:15That's one approach. Or we can simply
- 00:23:19incentivize this with more of a. Of a carrot approach rather than a
- 00:23:22stick.
- 00:23:28Thanks, Alex.
- 00:23:31Let's see. Michael.
- 00:23:32Jewellery.
- 00:23:43Michael, did you have something to add?
- 00:23:57Bill, go ahead. So I guess Bob,
- 00:24:00are you. The NPRR you're drafting will be an alternative to
- 00:24:03this. So instead of a compliance requirement
- 00:24:09it'll be a new product or something. Is that
- 00:24:12the idea?
- 00:24:24That was for you, Bob Helton.
- 00:24:28Katie,
- 00:24:33I can't hear Bob, but we can hear Michael now. So that's good.
- 00:24:36Some progress. Yeah. Something about WebEx, it's not allowing when
- 00:24:40you're connected by phone to necessarily get the mic to work.
- 00:24:45Is Bob available? But I didn't want to interrupt.
- 00:24:51I haven't heard Bob chime in so we'll let him jump in the queue if
- 00:24:54he's available. But we'll let you go ahead. Michael. Yeah, thank you. Sorry for
- 00:24:57the technical problems. Just following up,
- 00:25:01I think with what Jupiter, what Caitlin is talking about, what Bob was talking
- 00:25:04about is great. By way of example + power
- 00:25:08in Hawaii, the customer there wanted
- 00:25:12these additional functionalities and it was a paid for enhancement to
- 00:25:16the deployment of the ESR in order to be able to get that.
- 00:25:19That's the carrot kind of approach. That really does make sense because there
- 00:25:23are multiple values that you can get out of these,
- 00:25:28you know, four quadrant inverters thanks,
- 00:25:39Michael. We'll call
- 00:25:43for Bob one more time and then if not we'll go ahead and make the
- 00:25:46table and referral.
- 00:25:53Go ahead, Caitlin. Yeah, I just, I see Julia
- 00:25:58writing in the chat and so I kind of, I can't resist closing.
- 00:26:02I think that's sort of step one. You know, I stand
- 00:26:06on my policy cut and I
- 00:26:10think Bob Helton does too and I think we want to see that. But I
- 00:26:13think the problem with this NOGRR is written as
- 00:26:16the language is so vague we don't know exactly what
- 00:26:20is being looked for. And maybe this would help with Bill's
- 00:26:24questions as well. I think when you're talking about grid forming
- 00:26:28inverters, it's sort of one of those terms that can mean different
- 00:26:32thing to a different person. And so a true
- 00:26:36grid forming technology is something like Blackstart
- 00:26:39services. That is a product that should get paid. If we
- 00:26:43are looking for something that existing inverters can do,
- 00:26:47you know, but it's maybe maintaining something instead of following that's
- 00:26:52more narrow. I think that's maybe a different conversation.
- 00:26:55And so that's why you sort of have to have both conversations.
- 00:27:00And I, you know, I think Bob Helton and I would agree when
- 00:27:04we're talking about a paid product that is certainly something that we would
- 00:27:08think that the thermals and the people who provide inertia and
- 00:27:12stability as is would get paid for as
- 00:27:15well. I agree with Bob also on his causation points
- 00:27:19and especially in the context of ESRs, you know,
- 00:27:22that is something by nature of being able to
- 00:27:26charge and discharge. We locate specifically at
- 00:27:30places that would help with GTCs because that's also how
- 00:27:33we make money in the energy only market. Right. The price signals tell us,
- 00:27:37you know, sometimes this place needs something that is charging and sometimes
- 00:27:40it needs something that is discharging. So sort of inherent
- 00:27:44in our nature is helping with those GTCs to begin with
- 00:27:48and so understanding, you know, there's a lot of things changing
- 00:27:51on the grid where we could have more stability.
- 00:27:56But you know, I think the way this applies that to
- 00:28:00ESRs in particular is a little bit troubling.
- 00:28:08I appreciate that explanation. Two more in the queue.
- 00:28:12Fred, did you want to respond?
- 00:28:16Hi, this Fred, can you hear me? Yes,
- 00:28:19go ahead. Hi, thank you. I think I understand
- 00:28:23we will have some more discussion in the stakeholder meetings later
- 00:28:27on, but I just kind of want to provide
- 00:28:31a quick high level overview to the group.
- 00:28:36If you are not familiar with our proposal yet,
- 00:28:39I think it just to, I would say comments
- 00:28:43to several comments related to the technical part
- 00:28:48I think the first one is the technical details
- 00:28:52we have presented as kind of concept to
- 00:28:56the IBR working group on a regular basis and
- 00:29:01we also publish we call it a kite line for that one
- 00:29:05with the intention along with NOGRR and the PGRR here
- 00:29:09those requirements and performance expectation as Catherine mentioned
- 00:29:12is critical importance and we definitely recognize
- 00:29:16it. So our intention is to have those performance
- 00:29:21in terms of model quality how it should be verified
- 00:29:25check it. It will be part of the similar
- 00:29:29to our existing DW procedure menu for the
- 00:29:33other model performance and quality performance.
- 00:29:37That's where we intend to have all those details added
- 00:29:40to the DW procedure menu. I will be happy to work
- 00:29:45with the teams to see if there are other location is
- 00:29:48a proper way to include those technical performance details.
- 00:29:53But we do have those performance details defined and
- 00:29:56then we presented to IBR working group previously.
- 00:30:00The second one I would say the our proposal
- 00:30:05the intent is not to require
- 00:30:09additional hardware which as several
- 00:30:13commenters mentioned it in other regions because they
- 00:30:17have a specific need in
- 00:30:22their grid. So they
- 00:30:26do specify additional performance and need
- 00:30:30on hardware as a result they procure for it.
- 00:30:34Our proposal is expectation
- 00:30:39is not to require additional hardware and
- 00:30:43will not have impact to the normal operation.
- 00:30:49The need is when you are capable based
- 00:30:53on the condition you operated you can
- 00:30:57help to provide a support to the grid and that will provide a benefit
- 00:31:00to the grid for the security and security
- 00:31:04perspective. So just want
- 00:31:08to kind of point those two for the group to consider But
- 00:31:12I understand we can have we are going to have more discussion in
- 00:31:15the stakeholder meetings. Thank you.
- 00:31:19And another one quicker one I think we make it clear
- 00:31:23and we can definitely highlight it.
- 00:31:27Our proposal requirement is not required.
- 00:31:30We will not require in this proposal to have
- 00:31:34reforming provide a break start support.
- 00:31:38Thank you.
- 00:31:47Thanks Fred. I want to go back to Bob
- 00:31:51first. Sorry Julia, but Bob, did you hear Bill's
- 00:31:56earlier question? No, I didn't.
- 00:32:00If you repeat it and then I was going to comment on what Freddy's what
- 00:32:03Fred said. Okay. Bill, did you want to repeat your question?
- 00:32:08Yeah, sure. Bob, I was wondering if the NPRR that you are drafting is
- 00:32:12intended to be an alternative to this to replace it
- 00:32:16or something else? No, it would be what it would do
- 00:32:19is it would change. It would. It would likely get
- 00:32:23rid of the need for the NOGRR but it would not get rid of the
- 00:32:27need for the PGRR on the technical requirements.
- 00:32:31So does that help?
- 00:32:35Yeah. So how would it do that? It would instead of being some type of
- 00:32:38compliance requirement it would be a New paid product. Yeah, it'd be,
- 00:32:42it'd be a, an ancillary service. And then the technical
- 00:32:45requirements that you would need to meet to be able to supply that would be
- 00:32:49in the PGRR.
- 00:32:52Okay, okay, now on. I understand
- 00:32:56what Fred is talking about, but I do
- 00:33:00question one thing, Fred. I mean,
- 00:33:03if you make this an ancillary service because there is a need
- 00:33:07out there, you could in the PGRR put
- 00:33:11in any requirement you wanted, whether they would be software changes
- 00:33:15only or some hardware changes in there that you would feel would
- 00:33:19work for the system in a positive manner.
- 00:33:23And then it being a service, those that wanted to
- 00:33:27supply it would get under that and do make those changes that were necessary
- 00:33:31to even give more grid security than what you're
- 00:33:34kind of mandating out here right now. So I think that's the
- 00:33:37potential of changing this to an ancillary service is you
- 00:33:41figure out what you want and put it out there and see,
- 00:33:45you know, if you, if you put it out there, they will come. And so
- 00:33:50that's kind of what I was thinking about in this process also.
- 00:33:57Thanks, Bob. Okay, Julia's the last one
- 00:34:01in the queue. Go ahead, Julia.
- 00:34:05Yeah, I just wanted to iterate maybe like
- 00:34:09a little bit on what Fred said and kind
- 00:34:12of bring international perspective to that as well.
- 00:34:15So the way the requirements are defined is
- 00:34:19kind of normal way people do it today is
- 00:34:23because this is kind of different control strategy,
- 00:34:26but you don't want to be extremely prescriptive
- 00:34:30as to how people should do it. So the way it's
- 00:34:34been done in Australia defined in Finland,
- 00:34:37national grid in Great Britain, basically everyone is doing
- 00:34:41Hawaii. Somebody mentioned Hawaii here too. Everybody's doing
- 00:34:44it the same way is where you ask for this advanced
- 00:34:48grid support capability or call it grid forming capability
- 00:34:51and then it comes with the set of tests that
- 00:34:55are applied to models. And in those tests there
- 00:34:58is a description of what constitutes pass or fail.
- 00:35:02And so this set of tests, as Fred mentioned, was presented
- 00:35:06in August, IBRWG. There is a report posted on
- 00:35:10IBRWG webpage meeting webpage
- 00:35:14with all of this test and pass fail criteria. My understanding
- 00:35:18is as the follow up to this NOGRR and PGRR, this test
- 00:35:21will be integrated into DWG manual as
- 00:35:25the next step. So it's kind of similar to what we've done with NOGRR245
- 00:35:29is when NOGRR was already kind of reaching close
- 00:35:34to approval stages. Then DWG was updated, manual was updated
- 00:35:38with the tests of what it actually means.
- 00:35:41And so the same thing will happen here, but the tests are
- 00:35:45already published in this report
- 00:35:48that got produced. And so everybody is
- 00:35:51doing it that same way. There is no really very
- 00:35:56specific way to tell what grid forming should do
- 00:36:00without prescribing specific controls. And we
- 00:36:04don't want to do that because the pool of OEMs
- 00:36:07that can do grid forming is still relatively small. It's maybe 5,
- 00:36:117 OEMs that do offer this. They all do it in
- 00:36:15different ways so they achieve the same performance.
- 00:36:18But controls how they do it is different. And so by being prescriptive
- 00:36:23we may be narrowing it too much.
- 00:36:27Yeah. And to what Bob said there
- 00:36:31may be two pathways to this. And as
- 00:36:34Fred said, there is a lower hanging fruit of achieving
- 00:36:38this with batteries specifically for solar.
- 00:36:42You would need to back solar down to provide this capability
- 00:36:46because it needs energy buffer.
- 00:36:49For wind it's even more complicated because it has mechanical
- 00:36:53parts, rotating parts behind inverter. So applying this
- 00:36:57to wind it's even more complicated, more costly.
- 00:37:01From what we heard at IBRWG, if there is no extra
- 00:37:05hardware requirement to provide extra short circuit current or
- 00:37:08extra inertia or blackstar capability,
- 00:37:12it's just software changes. It doesn't have much
- 00:37:16of an extra cost. We didn't like nobody brought numbers.
- 00:37:19Everyone is saying it's like signal digit percent maybe cost
- 00:37:23difference, maybe there is no cost difference. Depending who you talk to,
- 00:37:26you hear different things. So I wanted to urge
- 00:37:29people as they talk to the OEMs actually get to the bottom of it,
- 00:37:32of what it costs. If you are saying that it costs something and
- 00:37:36then anything additional. As Bob
- 00:37:39said, if ERCOT feels later on down the road that this
- 00:37:43is needed then this can be implemented as a
- 00:37:46mark and specific requirements for specific quantities can be
- 00:37:50put out and paid for.
- 00:37:54So I have.
- 00:37:58Thanks Julia, thanks for the background.
- 00:38:01We've got a new queue forming and
- 00:38:05just to remind folks we are trying to get to a point that we refer
- 00:38:07this over to some working groups to have these more detailed discussions.
- 00:38:11So Fred, did you want to respond?
- 00:38:15I think I just want to probably
- 00:38:19maybe back to Bob and Catherine.
- 00:38:23When you try to think about the different way to such
- 00:38:27as market based way it will be helpful
- 00:38:32in that type of consideration.
- 00:38:36How to measure the need, how to quantify
- 00:38:40and how much you buy. I think Lowe's will be helpful if
- 00:38:44you can also share in a
- 00:38:48little bit. Consider there are some other existing.
- 00:38:53Yeah, so just kind of want to highlight that one.
- 00:38:56But I understand we have more opportunity for further discussion later.
- 00:39:01Thank you for all the comments. Thanks Fred.
- 00:39:04I think that makes sense. Okay, let's see
- 00:39:07Caitlin.
- 00:39:11Thanks, Katie. And thanks, Fred.
- 00:39:15That's a good point that we think about. Somebody pointed out to
- 00:39:18me offline that we do sometimes use RUC for stability
- 00:39:22purposes. So I think we could look at the amount that's being
- 00:39:25used and then the additional things
- 00:39:29we would want to see from a service like that,
- 00:39:33I think, and this will be my last comment, I promise, but I
- 00:39:36think we're getting into this cycle because I
- 00:39:42think by mandating this you need
- 00:39:45to get into specifics. I understand what Julia is saying,
- 00:39:49but my understanding is in those other countries
- 00:39:54this is a voluntary paid for service, like a stability
- 00:39:58service. And so I think that makes sense. If you're
- 00:40:02going out to market to see who can provide a service,
- 00:40:05that it be a little bit more vague and then you figure
- 00:40:09it out in testing requirements. Right, we do that now.
- 00:40:13We test our ancillary services and that's where you really see
- 00:40:16all the detailed work. And so
- 00:40:20I think it gets a little bit more difficult here
- 00:40:24because we as an owner want to
- 00:40:27make sure, we are an operator want to make sure we can comply
- 00:40:31with this. So also in response to Fred's comments that they don't
- 00:40:34envision a hardware upgrade if we don't meet the performance
- 00:40:38standards in the NOGRR, we can't go to the
- 00:40:42ERM and say, well, ERCOT didn't envision a hardware upgrade,
- 00:40:46so we stopped there and didn't meet
- 00:40:50the performance requirements. So I think that's where this gets pretty
- 00:40:53tricky and I'll leave it at that.
- 00:41:03Thanks, Caitlin. All right, we're back to Bob.
- 00:41:06Yeah, just one quick. And I like Caitlin, this will be my
- 00:41:10last comment is something Julia said. She was talking about, you know,
- 00:41:13the difference between solar and ESRs, where solar would have
- 00:41:17to back down. That reminded me of something that's in
- 00:41:21the paper that came out of the IBR working group. It said the reason that
- 00:41:25storage doesn't have to back down is because they don't operate all the way
- 00:41:29at the top. And that is true, but there are technical
- 00:41:32and operational issues of why we do that. So you are
- 00:41:35asking us to go outside of our normal operations,
- 00:41:39potentially to supply this. So I just wanted to bring that up.
- 00:41:49Yeah, thanks for the clarification,
- 00:41:52Floyd. Yeah, thanks.
- 00:41:55Maybe I misunderstood, but someone was talking
- 00:42:00about creating a new ancillary
- 00:42:03service. And if that is what you're
- 00:42:07doing, would that not have to be presented
- 00:42:11in an NPRR for a protocol change where
- 00:42:15all the ancillaries are defined?
- 00:42:18Yeah, that's exactly right. That's What Bob was saying
- 00:42:22that he is working on right now.
- 00:42:25Yeah, I misunderstood. It sounded like he was only
- 00:42:28talking about NOGRRs and planning guides.
- 00:42:33So I hope maybe
- 00:42:37I misunderstood what he was saying. Yeah.
- 00:42:40So he's looking at an NPRR that would be a replacement to the
- 00:42:44NOGRR, but the PGRR would still have all the specifications in
- 00:42:47it for the service. Remember,
- 00:42:50in section 8 of the protocols is where performance
- 00:42:54requirements are specified.
- 00:43:00So what we don't want to do is mix them all up in different places
- 00:43:04in different documents if it's a new ancillary.
- 00:43:11Thanks. Yeah, thanks, Floyd.
- 00:43:16Okay with that. I appreciate all the discussion
- 00:43:20today. And I'll go back to what we talked about
- 00:43:24doing originally, which is to table and
- 00:43:28refer. Going to go ahead and put the PGRR together because we did
- Item 5.3 - PGRR121, Related to NOGRR272, Advanced Grid Support Requirements for Inverter-Based ESRs00:43:32talk about it as well. So
- 00:43:35NOGRR272 and PGRR121,
- 00:43:39send those over to DWG and IBRWG
- 00:43:45and if no one is opposed to adding these to the combo ballot,
- 00:43:48that's what we'll propose to do.
- 00:43:52All right, that looks right to me, Erin. Thank you.
- Item 5.4 - PGRR122, Reliability Performance Criteria for Loss of Load00:44:07All right, and that will take us on to
- 00:44:11PGRR122 reliability performance criteria for
- 00:44:16loss of load. This is
- 00:44:21kind of a follow on to NPRR1234
- 00:44:25and PGRR115 dealing with large
- 00:44:29loads and now putting in sort
- 00:44:33of this performance criteria with a 1000 megawatt
- 00:44:37limit for any large loads.
- 00:44:42Is someone, does someone from ERCOT want to speak to this?
- 00:44:45Hey Katie, this is Jeff Billo. I can talk to this one.
- 00:44:50So on this one,
- 00:44:54as many of you know, we're seeing an increasing number of
- 00:44:58really large loads that are connecting to our system or
- 00:45:02at least requesting to connect to the system. And we know from
- 00:45:07the Southern Cross studies that we did that
- 00:45:12under certain conditions, if you lose too
- 00:45:16much demand on your system, on the ERCOT system,
- 00:45:20then it will cause frequency to spike such
- 00:45:24that the generators on the system will
- 00:45:28trip on over frequency, which will lead to
- 00:45:31a frequency instability condition.
- 00:45:36So obviously that's a bad thing. So based
- 00:45:39on that we decided to
- 00:45:43put this figure out that
- 00:45:47essentially would create the requirement that if
- 00:45:52we identified in studies, either in the interconnection
- 00:45:55studies of large loads or the regular
- 00:45:59planning studies, if we identified a condition where we lost
- 00:46:03more than 1,000 megawatts for any single contingency,
- 00:46:07then we would need to do system upgrades
- 00:46:12which would likely be like a synchronous condenser
- 00:46:16or grid forming statcom or something like that
- 00:46:19to try to support the system. So that you're not losing that
- 00:46:23much. And really the condition is either you have a single load or you
- 00:46:26may have multiple load, large loads in a single area that would
- 00:46:30see the voltage depression under a fault. So that's
- 00:46:33the intention here. I think DWG
- 00:46:38has proactively, I think they're taking it up
- 00:46:41at their next meeting, which I think is next week.
- 00:46:45And I think that we would probably expect
- 00:46:48that we probably want to talk about this at PLWG.
- 00:46:52So with that I'm happy to answer any questions.
- 00:46:57Thanks, Jeff. Yeah, that was my thought was to
- 00:47:01table and refer this over to DWG and PLWG and
- 00:47:06just wanted to make sure everybody else was okay with
- 00:47:09that.
- 00:47:22Looks like Brian has a question in the chat. Chat for you,
- 00:47:26Jeff. Can you describe what you mean by multiple loads in
- 00:47:29an area? Yeah, so, so again,
- 00:47:33what, what we're looking at is the potential for loss
- 00:47:37of a lot of loads on the system.
- 00:47:41And you know, it could be that you have a single
- 00:47:451000 megawatt load that you,
- 00:47:48you would have, you know, maybe a fault at the substation and it, it trips
- 00:47:52that load off. You could also have a situation
- 00:47:55where maybe you have maybe two 500
- 00:47:59megawatt loads in an area or
- 00:48:03bigger than that. You could have two 600 megawatt loads where
- 00:48:07if they're nearby, if you have a fault in the area, then your
- 00:48:11voltage depression is going to be such that
- 00:48:14if they don't have voltage right through capability then they're going
- 00:48:18to drip and so you could have that. That situation also
- 00:48:22cause frequency instability.
- 00:48:30Thanks, Jeff. Yeah, and just a reference for that.
- 00:48:34So I think we have been talking about this
- 00:48:38voltage right through issue with the large loads and some
- 00:48:42actual events that we've seen at both OWG
- 00:48:46and PDC. And so I think that on
- 00:48:50some of their meetings that somebody from ERCOT or one
- 00:48:53of those working groups can correct me if I'm wrong, but I think that we've
- 00:48:56posted presentations at least at the.
- 00:48:59I think it was the last OWG meeting where we had a
- 00:49:03discussion about this.
- 00:49:07I think it was also at PDCWG as well. I remember
- 00:49:10two working groups discussing it. Okay, we've had
- 00:49:14a couple folks jump in the queue.
- 00:49:19Oh, thanks, Nitika. So you all can find
- 00:49:23that presentation linked in the chat from Nitika.
- 00:49:26Yep, PDC. Okay, thank you for confirming. I misremember.
- 00:49:30All right, so we've got Chase and then Brett.
- 00:49:37Thank you. Katie, can you confirm you can hear me?
- 00:49:42We can't. Go ahead. Thank you.
- 00:49:46Thanks, Jeff. This is, this is Jason with Southern Power can you you
- 00:49:50kind of further explain just how UR is thinking about
- 00:49:56the situation that I was reading in the kind of justification
- 00:50:00that, you know, ERCOT has seen some interconnection load requests
- 00:50:04that are bigger than one gigawatt and then you know I'm seeing
- 00:50:08some of the language that for these contingency
- 00:50:12events, you know, you want to limit where the total load loss shall be less
- 00:50:15than 1 gigawatt. So like how can you just help explain I'm trying
- 00:50:19to understand what does that mean if you have a new load that's proposing
- 00:50:23to interconnect and it's greater than 1 gigawatt,
- 00:50:26is that allowed? Is it just potentially mitigating actions that need
- 00:50:30to be, you know, you know,
- 00:50:33equipment or similar other mitigating actions to,
- 00:50:37you know, reduce the risk of load loss. I'm just
- 00:50:41trying to understand how to square that away if you have
- 00:50:45a load project that just in itself is greater
- 00:50:48than the 1 gigawatt threshold that's described in the figure.
- 00:50:53Yeah, thanks Jay. So if you look at so
- 00:50:57this is somewhat addressed in I think it's PGRR115 it's the
- 00:51:01bigger that goes with NPRR1234 we
- 00:51:06filed comments in there that if
- 00:51:10you have a load that is larger than
- 00:51:141 GW then you would need to
- 00:51:18the way that that would need to be connected would be you
- 00:51:22couldn't just have a single point of interconnection for all.
- 00:51:26So if you had the 2 gigawatt load as an example, you can't just have
- 00:51:29a single point of interconnection for that entire 2 gigawatts that
- 00:51:33would need to be split into multiple interconnections.
- 00:51:38And again the same idea is that you wouldn't wouldn't want to
- 00:51:41have more than 1,000 megawatts of
- 00:51:46load loss for any single event. So whether that's
- 00:51:49you lose the the POI connection or
- 00:51:53if you had a fault on the system and you had a ride
- 00:51:57through event, the system can't handle
- 00:52:01more than, you know, losing more than that amount for any single
- 00:52:04event.
- 00:52:11Okay, thank you Jeff, that's helpful. And I hadn't
- 00:52:14quite made that connection with NPRR1234 so thank you
- 00:52:18for clarifying.
- 00:52:22All right, let's take it to Brett and then on to
- 00:52:26Shane. Thank you. I had a similar question
- 00:52:31just on why 1 gigawatt so I really appreciate the
- 00:52:34explanation Jeff.
- 00:52:38Sure. Thanks Brett. Shane all
- 00:52:43right. Yeah, thank you Shane Thomas Michelle had a
- 00:52:46couple questions. One is the is around the
- 00:52:50multiple load scenarios and
- 00:52:54is that so the will the earnest be on the second
- 00:52:57load, I guess, you know, as their loads are building up in an area.
- 00:53:00We would see the study that there's already a 600 megawatt load, someone's requesting
- 00:53:03another 600. And we would, the new load would be
- 00:53:07potentially limited to 400 megawatts or no,
- 00:53:10399 or whatever to keep them below a thousand total
- 00:53:14for this, you know, radial line or whatever we're
- 00:53:18talking about here. Yeah. SHANE so I think for
- 00:53:22that scenario, I think there are a couple of options. So let's
- 00:53:26say you had, if I understood your scenario correctly,
- 00:53:30you had 600 megawatts in an area and
- 00:53:33then you had another 600 megawatt load that wanted to connect in
- 00:53:37that same area. And let's say neither of them were able to
- 00:53:41ride through a voltage depression.
- 00:53:44I think, you know, one option would be that
- 00:53:48that second load would need to be able to
- 00:53:52ride through, you know, that they would have to do whatever they
- 00:53:55need to do on the load side to be able to ride through a voltage
- 00:53:59depression. Another option would be, you know,
- 00:54:03if they're far enough apart, then maybe you could put in a,
- 00:54:08you know, a synchronous condenser or, you know, something like that to strengthen the
- 00:54:11system so that both facilities at
- 00:54:15the same time wouldn't see such a voltage depression for a fault.
- 00:54:20And then, you know, another option would be you could,
- 00:54:24you know, just limit that facility, that second facility to 400
- 00:54:27megawatts. But I think those are all potential options
- 00:54:31for that scenario. But I think we're trying not to be
- 00:54:35that prescriptive here. We're just trying to identify this
- 00:54:40is the system limit, this is how much the ERCOT system
- 00:54:44can handle and kind
- 00:54:48of leave the door open for whatever options may
- 00:54:51solve the identified issues. Okay, yeah,
- 00:54:55thank you. I mean, I appreciate y'all too, being super open to
- 00:54:58creative solutions around this and not just blanketing
- 00:55:02a 1000 megawatt cap out there.
- 00:55:06Another question then is on, I guess, for these studies, are we
- 00:55:10looking for, is everything going to be based on
- 00:55:13the requested interconnection amount? So, you know, loads that
- 00:55:17maybe have requested for a thousand megawatts,
- 00:55:20but after four years you're sitting at 200
- 00:55:24still, or how is there any kind of thought to how that
- 00:55:27gets handled? Or is it, are they just get those thousand megawatts
- 00:55:31for the lifetime of their project or, you know.
- 00:55:37Yeah, yeah. Honestly, I haven't thought that
- 00:55:40closely about that. That's a good thing to think about.
- 00:55:43SHANE Just off the top of my head, I think it
- 00:55:46would be whatever it depends what the
- 00:55:50study you're looking at. Right. If you're looking at an interconnection study and I'm
- 00:55:53assuming that the TOs are going to study whatever the requested
- 00:55:58amount is, but I think going forward if they request a thousand,
- 00:56:02but maybe they only sign an agreement for say 500,
- 00:56:05I think in your planning studies you would just use, you know,
- 00:56:09your annual planning studies, you would just use whatever they have signed
- 00:56:12in their agreement.
- 00:56:15Okay, yeah, that'd be, I guess that can be handled. Part is like
- 00:56:19keeping those numbers updated in the large
- 00:56:23load process and things like that or when we're updating numbers annually,
- 00:56:29something like that. But looking forward to continuous
- 00:56:33discussion in the other other forums.
- 00:56:36Thank you. Thanks,
- 00:56:39Shane.
- 00:56:43Yeah, that's a good point, Bill.
- 00:56:47Yeah, I think there has been some discussion under NPRR1234 about this
- 00:56:50as well. Bill, do you have a question?
- 00:56:54Yeah, Jeff, Is this requirement specific to
- 00:56:58standalone large loads and
- 00:57:02not co located large loads?
- 00:57:08I think it is not
- 00:57:14a requirement on the load. It's a system requirement.
- 00:57:19Right. So it is. You couldn't.
- 00:57:23The system can't handle more than
- 00:57:271,000 megawatt load loss. And so it's really
- 00:57:31whether you identify that and like I said your interconnection study
- 00:57:34or your annual
- 00:57:39planning studies or any other planning study,
- 00:57:45it's really a system requirement. So just
- 00:57:50thinking out loud through that scenario, if you had a co located,
- 00:57:54if you had something more than 1,000 megawatts co located
- 00:57:58with a generator, if it's possible
- 00:58:01to lose that load by itself without
- 00:58:05losing the generator, then I would say that that
- 00:58:09would be a bad thing. Right. You wouldn't want a 2000 megawatt load
- 00:58:13drop just because it's located next to
- 00:58:17a generator. The system is going to see that frequency spike
- 00:58:21regardless. Right. So I think we would look at it more
- 00:58:25from that perspective. So a 1500 megawatt load
- 00:58:29behind a thousand megawatt thermal plant would not raise
- 00:58:33a concern for ERCOT because the system only sees a 500 megawatt drop?
- 00:58:37Well, I think it depends if that load.
- 00:58:41If you could drop that 1500 megawatt load and
- 00:58:45that thousand megawatt generator would still be there. I think
- 00:58:49that would be a concern. Right. Because the system is going to see that frequency
- 00:58:52see spike. The system is going to see the 1500 in
- 00:58:56the, in a different direction though. It's a, that's a different.
- 00:58:59Right. That is. That doesn't look like that's what you're trying to address here.
- 00:59:03Or is it. That's the question is.
- 00:59:06Yeah, it's it's from a. What is the system going
- 00:59:10to see? So, so if you had a contingency where the
- 00:59:13system is going to see 1500 to, even if it's behind the fence,
- 00:59:18if you lost 1500 megawatts,
- 00:59:21if you lost the load but did not lose the generator,
- 00:59:25then that would be bad for the system.
- 00:59:30Okay,
- 00:59:37thanks Jeff. One more in the queue and then we'll work on
- 00:59:40doing our referral. Andy, you've got the last question.
- 00:59:44Yeah, thanks. Katie, can you hear me?
- 00:59:49I can hear you, go ahead. Okay, thanks. Yeah, wanted to
- 00:59:52follow and unpack the thread on Jeff and Bill's conversation.
- 00:59:56In that scenario, Jeff, if the load were to
- 01:00:00trip offline, but then the generator had special
- 01:00:04relays that also tripped such that the net
- 01:00:08impact to the grid was below that thousand megawatts,
- 01:00:12would that be acceptable to ERCOT? So in Bill's example
- 01:00:17you had a 1500 megawatt load that tripped,
- 01:00:21but then you would subsequently also trip the generator in such a way where
- 01:00:26the impact was less than a thousand. Could you help? Has ERCOT
- 01:00:30thought about that type of configuration and the risk?
- 01:00:35Yeah, so I,
- 01:00:39I think potentially I, I think that we would,
- 01:00:45you know, I think we'd have to look at the specifics of that, that situation.
- 01:00:49And, and also, you know,
- 01:00:52also, you know, is that a RAS or,
- 01:00:56you know, is it more kind of inherent in the design?
- 01:01:00I, I think we'd have to of look at that if it's a RAS,
- 01:01:05you know, I think that that could be problematic from. I think NERC
- 01:01:09wouldn't let us have a RAS that,
- 01:01:13you know, if it misoperated, could cause a stability issue.
- 01:01:17But yeah, I think, you know, that that kind of situation
- 01:01:21I think we'd have to look at on a case by case basis.
- 01:01:26Yeah, that makes sense to me Jeff. I just want to make sure. And then,
- 01:01:29and as we think through this and as it gets referred,
- 01:01:33you know, those are the type of things that if could be
- 01:01:36configured correctly, could actually help ERCOT because it
- 01:01:41helps to avoid these type of situations where you could have
- 01:01:44some voltage instability in tripping scenarios. So appreciate
- 01:01:48the time. Thanks Kevin. Thanks,
- 01:01:51Andy. Kevin?
- 01:01:54Yeah Jeff, quick question. Are you guys talking to other ISOs as
- 01:01:58well? Cause I believe I thought I saw Entergy is looking to add 4 gigawatt
- 01:02:03data storage site on their side. So I'm assuming myself looking at as well.
- 01:02:12Sorry Kevin, I didn't catch all of that. Can you repeat that? Yeah, yeah.
- 01:02:15My comment is are you talking to the other ISOs in sync? You're talking
- 01:02:18part of NERC. So I'm assuming all the ISOs are going to be under the
- 01:02:21same rules and requirements. And I believe I just saw
- 01:02:25recently that Entergy is looking. They're looking to have a potential
- 01:02:29new 4 gigawatt new data center load over there that
- 01:02:34I understand we're talking 2 to 4 gigawatts over here. I'm just wondering if you
- 01:02:37reach out to other ISOs and having conversations about how
- 01:02:41they're dealing with it on their side as well. Yeah,
- 01:02:44so yes, we are talking to
- 01:02:48other ISOs, both in the United States
- 01:02:52as well as globally.
- 01:02:56I think we're also. There's a NERC task force, there's an ESIG task
- 01:02:59force, so we're involved with all of that.
- 01:03:02I think within the U.S. what makes us a little unique
- 01:03:05is the size of our system. You know,
- 01:03:09it may be that the Eastern interconnect,
- 01:03:12because it's a larger system, can withstand larger load loss,
- 01:03:16same with the West. So that, that may not
- 01:03:19be as applicable. But you know, some of the
- 01:03:23other countries that we've talked to that, you know,
- 01:03:26have smaller systems, I think they're looking at something similar.
- 01:03:32Thanks, Jeff. I appreciate it.
- 01:03:35Thanks, Jeff. That's a good point. Okay,
- 01:03:39so that's everybody in the queue. So. So let's go back to what we
- 01:03:42originally talked about. So we talked about sending
- 01:03:48this over to PLWG and
- 01:03:51DWG for more discussion.
- 01:03:55So I didn't hear anyone with concerns about
- 01:03:59that. So I think we can add that to the combo ballot.
- 01:04:02Erin?
- 01:04:10Perfect. All right, thank you for that.
- Item 6 - New Protocol Revision Subcommittee - PRS - Referrals - Vote - Katie Rich01:04:24That takes us on to NPRR1257.
- Item 6.1 - NPRR1257, Limit on Amount of RRS a Resource can Provide Using Primary Frequency Response01:04:29So this is the limit on responsive
- 01:04:32reserve as a resource. So there
- 01:04:36was a study done on this and
- 01:04:39ERCOT came back with this initial
- 01:04:43limit of 156 megawatts. I know that
- 01:04:46this was discussed at PDCWG.
- 01:04:49I know that Jupiter Power had some initial concerns.
- 01:04:53And Caitlin, I believe that
- 01:04:56you're now coming back and saying that you're more comfortable with this.
- 01:05:01And so did you want to add anything or Kevin,
- 01:05:05did you want to add anything from a PDC perspective or did
- 01:05:08you want to talk about that when we get to you? Caitlin,
- 01:05:12go ahead. Thanks, Katie,
- 01:05:16and thanks, Kevin, for letting me come to your PDC meeting
- 01:05:19and derail it for a bit. We did have some concerns
- 01:05:23that concern concerns were with regulatory
- 01:05:26certainty because this is going to be changed in
- 01:05:30the ancillary service methodology every year or potentially
- 01:05:34changed. And so I did talk to Nitika
- 01:05:39offline and alleviated those concerns. Just kind of the outlook
- 01:05:43of what is going to be needed, inertia wise
- 01:05:47and ancillary services. We don't see a big swing
- 01:05:51happening, I think in the next five years or so. And so we
- 01:05:55feel good about it. But the initial concern was if
- 01:05:59the 157 megawatts were to go down to
- 01:06:0295 megawatts or something that is
- 01:06:06difficult for us to plan around.
- 01:06:15That's all I got. Thanks,
- 01:06:19Caitlin, Kevin. And from the PDC perspective, we didn't
- 01:06:22really discuss it too much. We talked about it several months ago.
- 01:06:26No one really had any comments since Caitlin
- 01:06:30and ERCOT had already discussed it previously before the meeting occurred,
- 01:06:34we really only brought it up. We gave people the opportunity to speak to it
- 01:06:37they felt necessary. We moved past it under
- 01:06:41five minutes.
- 01:06:44And Kaylin, you're always welcome to interject into PDC.
- 01:06:50That's great. And I heard that you're going to chair it next year.
- 01:06:53So I'll come back. We'll discuss that later
- 01:06:58in the meeting.
- 01:07:02Yeah, I don't want to cause any conflicts. I heard something else that
- 01:07:06people PDCWG, so I'll just be quiet,
- 01:07:10though. So on this topic, that brings
- 01:07:13us to the question of if PBCWG's
- 01:07:17looked at it and they're
- 01:07:23ready to advance it, is ROS ready
- 01:07:27to move it forward as well, or do you feel like you
- 01:07:30need any additional time to look at this?
- 01:07:46Okay, so absence of comments, does that
- 01:07:50mean that we could try to move this forward? If so,
- 01:07:54I'd have Erin put something on the combo ballot approving
- 01:07:58NPRR1257.
- 01:08:01Okay, thanks, Erin. We'll leave that there,
- 01:08:05see if anybody brings anything up as we look at the combo ballot
- 01:08:09later.
- Item 7 - Revision Requests Tabled at PRS and Referred to ROS - Possible Vote - Katie Rich01:08:17All right, so that takes us to 7
- Item 7.1 - NPRR1229, Real-Time Constraint Management Plan Energy Payment01:08:21and 8, which are tables. Items NPRR1229
- 01:08:28looks to still be at WMS
- Item 8 - Revision Requests Tabled at ROS - Possible Vote - Katie Rich01:08:31having, you know, some discussion with ERCOT on those. And
- Item 8.1 - PGRR073, Related to NPRR956, Designation of Providers of Transmission Additions01:08:36PGRR073 has been on here for quite a while,
- 01:08:41so I think we'll just leave it where it is. And that will take
- 01:08:44us into our working group updates and OWG
- Item 9 - Operations Working Group - OWG - Rickey Floyd01:08:49is first up. So, Ricky, were you going to give
- 01:08:52that update? Good morning, this is Tyler. Can you hear me?
- 01:08:58We can go ahead. Okay, perfect.
- 01:09:01We can go ahead and go to the next slide. Should be a pretty quick
- Item 9.1 - NPRR1070, Planning Criteria for GTC Exit Solutions - OWG, PLWG- Possible Vote01:09:05update. NPRR1070 remains
- Item 9.2 - NPRR1238, Voluntary Registration of Loads with Curtailable Load Capabilities - OWG - Possible Vote01:09:09tabled at OWG. NPRR1238
- 01:09:14As of the last meeting,
- 01:09:18we were still waiting on ERCOT to file their
- 01:09:21comments. For ERCOT's comments at the meeting, they were
- 01:09:25still under review.
- Item 9.3 - NOGRR265, Related to NPRR1238, Voluntary Registration of Loads with Curtailable Load Capabilities - OWG - Possible Vote01:09:30And then NOGRR265,
- 01:09:34that would be the same. Still waiting on ERCOT's comments, so hoping
- 01:09:38to have those for our next meeting.
- 01:09:42I don't know if ERCOT can comment on that here if we'll have him for
- 01:09:45the next meeting or not.
- 01:09:58Freddy, can you address that or someone else from ERCOT.
- 01:10:04Hi, this Fred. I think our SME
- 01:10:08is not available today. I will take this one
- 01:10:11back and provide a quick update back to you and OWG
- 01:10:18chair. Thanks Jack,
- 01:10:23will you do. Thank you. And then next slide
- 01:10:26was just other business and we didn't discuss any other business at
- 01:10:30the last meeting. So thanks everybody.
- 01:10:39All right, thanks for your update.
- 01:10:44That will take us down to PLWG.
- 01:10:52Thanks Katie.
- Item 10 - Planning Working Group - PLWG - Dylan Preas01:10:57Good morning ROS. This is Dylan Preas. I'm the PLWG
- 01:11:01Chair. I'll be giving the report this
- Item 10.1 - PGRR115, Related to NPRR1234, Interconnection Requirements for Large Loads and Modeling Standards for Loads 25 MW or Greater - PLWG - Possible Vote01:11:04morning. So PLWG met on November 12th
- 01:11:08where we discussed PGRR115 interconnection requirements
- 01:11:11for large load and modeling standards for loads 25 megawatts or greater.
- 01:11:16At the November 12th meeting, ERCOT reviewed
- 01:11:21reply comments to the PGRR dated November
- 01:11:2411th as well well as reply comments to the NPRR1234 also dated November 11th.
- 01:11:29Discussion at the meeting included potential overlap of
- 01:11:33PGRR115 with a new PGRR122 with questions
- 01:11:36related to the 1000 megawatt total load loss limit
- 01:11:40in PGRR122. So we've heard from Jeff on this
- 01:11:43one and I do did catch the combo
- 01:11:46ballot vote to take this one up at PLWG should that come our way.
- 01:11:50We did. Table PGRR115 for further
- 01:11:55discussion in December slide
- Item 10.2 - PGRR119, Stability Constraint Modeling Assumptions in the Regional Transmission Plan - PLWG - Possible Vote01:11:58PGRR119 Stability constraints Modeling
- 01:12:06assumptions in the regional transmission plan. So as a reminder,
- 01:12:10in this one it was submitted by ERCOT and it formalizes the existing
- 01:12:13practice in which ERCOT applies a reliability margin
- 01:12:17for example 10% 2 stability constraints
- 01:12:21when ERCOT models stability constraint in RTP
- 01:12:24reliability in economic cases. At the
- 01:12:28meeting we reviewed OPUC November 6th comments and
- 01:12:31after discussion field PLWG reached consensus on the
- 01:12:35original version of PGRR119 submitted by
- 01:12:39ERCOT on September 12th. I'm sorry, September 9th.
- 01:12:42Don't know if we need to have some discussion on
- 01:12:49PGRR119. We do have PLWG consensus
- 01:12:53for a vote. We did see comments come out from joint
- 01:12:57commenters I guess.
- 01:13:01Alex, maybe you in. Yeah, you.
- 01:13:04Alex, maybe you in. Yeah, you.
- 01:13:08You read my. Yeah, I was just. I was just going to note that
- 01:13:13we did. Sorry for the timing issue.
- 01:13:16We did try to try to indicate that we would be filing comments
- 01:13:20but we did file a
- 01:13:24set of comments with suggested edits and clarification
- 01:13:28that helped with. We think some of the concerns that had
- 01:13:31been brought up by the other commenters
- 01:13:37and adding more clarity to the intention there. So we
- 01:13:40would love for it to go back to PLWG if possible, but leave
- 01:13:44it to the group so
- 01:13:55PLWG can certainly take it back. So if
- 01:13:58that's the will of ROS, then we'll add it back
- 01:14:02to our agenda at our December 18th
- 01:14:06meeting.
- 01:14:10Am I hearing that the
- 01:14:13will of ROS? Katie I'm
- 01:14:17hearing silence, except from Alex. I'm fine
- 01:14:21with that. I've had to send
- 01:14:25things back in the past. So considering that you do have
- 01:14:29another meeting and this month and we can
- 01:14:32wrap it up by the end of the year, I think it wouldn't hurt to
- 01:14:36have one more discussion, if you don't mind. Dylan. Okay,
- 01:14:39so we'll take that one back and get it on our next Very
- 01:14:46good. Appreciate that. Slide please.
- Item 10.3 - PGRR120, SSO Prevention for Generator Interconnection - PLWG - DWG - Possible Vote01:14:51PGRR120 SSO Prevention for Generator
- 01:14:56Interconnection this was a new one at PLWG in November,
- 01:14:59and as a reminder on this 1, PGRR120 will prohibit future
- 01:15:03generation resources from interconnecting on a serious compensated
- 01:15:07circuit such that an n minus one contingency event would
- 01:15:11cause the generation to become radial to a series capacitor.
- 01:15:15ERCOT presented the overview of the draft presentation
- 01:15:19at PLWG. I think it was the same one that RA ROS saw at the
- 01:15:23at the prior ROS meetings we had discussion
- 01:15:26on this one related to the SSO study process, potential OEM
- 01:15:30technology to mitigate effects of SSO and recent
- 01:15:33SSO events impacting multiple generators were discussed
- 01:15:37and PLWG would like to table this one pending
- 01:15:41further discussion at the December meeting.
- 01:15:48No questions on that one. Move on to the next slide.
- 01:15:51So NERC Topics Roundtable is something we carry forward still hot topics
- 01:15:55in Affecting Planners in the NERC arena or NERC
- 01:15:58CIP-014-4, which is a new revision working
- 01:16:02its way through the review process at the NERC
- 01:16:06level as well as TPL-008-1
- 01:16:10Transmission Planning Performance Requirements for extreme weather.
- 01:16:14We we carry these round tables when we have time to discuss them.
- 01:16:17Typically we've been pretty busy so we just we just flag the most recent information
- 01:16:21on them at our meetings.
- 01:16:28Next slide. We do have
- 01:16:31one open action item that's a review of Load Capital
- 01:16:34Capital L load in the Planning Guide. Revise as needed.
- 01:16:38That is to align the terms load and
- 01:16:42Big L load in the Planning Guide with
- 01:16:46the defined term in protocol section 2.
- 01:16:49Action item on this one is to take up one section of the Planning Guide
- 01:16:53at each meeting. We'll start that at our Next meeting in
- 01:16:56December. We're all still seeking a sponsor
- 01:17:00to oversee the revision request. That's something we'll work through.
- 01:17:04But we are working on this action item and
- 01:17:12any questions for me?
- 01:17:17I just wanted to say thank you. I know that you know your group in
- 01:17:21particular has had a lot of work this year and you
- 01:17:24really tremendously helped with NPRR1247. So thank you
- 01:17:28for that. Thank you for taking PGRR119 back for
- 01:17:32one more month and thank you for laying out a
- 01:17:36plan to work on this open action item.
- 01:17:39I appreciate that very much. So thank you for all that you did
- 01:17:42this year. Appreciate it. Thank you very much.
- 01:17:47Thanks everyone.
- Item 11 - Performance, Disturbance, Compliance Working Group - PDCWG - Kevin Bunch01:17:53Okay, let's see if we can keep rolling a little bit. Let's go to PDCWG.
- 01:17:57Kevin, you're up. I hear you got nominated
- 01:18:01for next year but we'll let you clarify what you meant.
- 01:18:06Yeah, next slide. So we met last
- 01:18:10month. You go to the next slide.
- 01:18:14My presentation will be pretty short since but
- 01:18:18we did discuss NPRR1257 pretty briefly the
- 01:18:25load loss analysis. We went to some detail however
- 01:18:30below TRE-2
- 01:18:35but this is the load loss analysis One of the
- 01:18:38paths I believe from 2020 to 2023 in
- 01:18:43a large load there are
- 01:18:46several of eight sequel events were
- 01:18:54involved in the IBR generations and
- 01:18:59all the events were identified by ERCOT operations in real time.
- 01:19:03So they continue to monitor that before
- 01:19:06they go for from here.
- 01:19:12Sorry, this was it.
- 01:19:16The ERCOT will be presenting next week.
- 01:19:22Activate again. ERCOT will be presenting at OWG
- 01:19:26and LFTF in the
- 01:19:29next meeting. They'll be presenting the large loss analysis
- 01:19:33there as well. If you have any questions
- 01:19:37on the load loss analysis. Yeah,
- 01:19:46I'm not seeing any there.
- 01:19:50We had our typical frequency control metrics that's
- 01:19:55present every single month. That's at the very bottom of this presentation you go through
- 01:19:58there's
- 01:20:02some reports so I don't go over that great detail
- 01:20:06Tre get their typical updates and
- 01:20:12the last thing I had on here is there's no FMEs
- 01:20:16for this month.
- 01:20:22Our IMFR is four times what
- 01:20:25it needs to be. So we're doing fantastic there and
- 01:20:29honestly the the best there.
- 01:20:32The most important update I had for you from PDC was
- 01:20:35despite rumors started earlier this meeting I will not be chairing
- 01:20:39again next year. Chad has graciously
- 01:20:43agreed to stay on in some form of leadership role.
- 01:20:46So if you're interested in sharing or advice sharing PDCWG please
- 01:20:51let me know any
- 01:20:59questions. Thanks Kevin. It's always great when Caitlin comes
- 01:21:02to our meeting and tries to Start trouble.
- 01:21:05Yes, I have to do a TAC leadership request.
- Item 11.1 - NOGRR271, Related to NPRR1257, Limit on Amount of RRS a Resource can Provide Using Primary Frequency Response - Possible Vote01:21:12Okay. The Other thing that Nitika reminded me of
- 01:21:16is we added NPRR1257
- 01:21:20to the combo ballot, which left
- 01:21:23NOGRR271 right to be added as well.
- 01:21:27So, Kevin, unless you have any opposition to that,
- 01:21:30I think we'll go ahead and add that one as well. No, I believe they
- 01:21:33go hand in hand. I don't think you have one without the other.
- 01:21:38Okay, thank you. Thanks for your leadership this year.
- 01:21:45All right, we got that added.
- Item 12 - Network Data Support Working Group - NDSWG - Gerardo Escamilla01:21:48Okay, let's take it now to NDSWG.
- 01:21:58Oops. Can I do.
- 01:22:01Oh, can you hear me?
- 01:22:07We can go ahead. Oh, my goodness. Okay, great,
- Item 12.1 - NPRR1234, Interconnection Requirements for Large Loads and Modeling Standards for Loads 25 MW or Greater - NDSWG - Possible Vote01:22:11great. Thank you. Yes, good morning. I'm doing a
- 01:22:14standard report. I know it says NPRR1234.
- 01:22:20Can we go to the next slide, please?
- 01:22:25So basically on our last meeting, November 19,
- 01:22:282024, we pretty much discussed
- 01:22:32basically modeling top lines, but only we have
- 01:22:35serious compensators. Who wanted to know? Well, I guess I'm jumping,
- 01:22:39jumping the gun here. Well, I guess. Yeah.
- 01:22:42Similarly, during pen lines and we're updating NMMS model breaker validation
- 01:22:46rules, updating the NMMS CIM upgrade project, and then
- 01:22:50of course the 2025 Share By Share nominations and other topics.
- 01:22:53Next slide, please.
- 01:22:57So, yes, right here is where I'm meant to be talking about this.
- 01:23:01Sorry. The. The Marlin zero impedance lines
- 01:23:04were. This is an effort that we're trying to do for
- 01:23:09our EMS system to be matching the ERCOT main system.
- 01:23:13And basically what we're just doing here is just seeing if
- 01:23:17we can remove the existing series compensators model in the model
- 01:23:21and just put zero impedance lines in between. Pretty much that's
- 01:23:24the essence of this effort here for
- 01:23:28the evaluation rules. That was something that ERCOT
- 01:23:32is doing right now for assigning PSSEID
- 01:23:35to the nodal breaker model.
- 01:23:39And this is an effort that we are doing with
- 01:23:43planning to make sure that we
- 01:23:48agree on what the ID should be for devices like breakers,
- 01:23:51lines, substations and shunts and loads and all
- 01:23:55that. Next page,
- 01:23:58please. Next slide. I'm sorry.
- 01:24:04And then of course, the update to the NMMS and SIM upgrade project
- 01:24:08and the go live is first quarter of 2027.
- 01:24:11CIM model will be available in
- 01:24:14the full redacted model. And this is for, I guess,
- 01:24:18importing models into our EMS to make it
- 01:24:22equivalent to the MAGE model.
- 01:24:26Then we're going to the vice chair and sharing vice chair nominations.
- 01:24:29We have stepping out from vice chair position to
- 01:24:33share Phil Hoffer from AEP and Teddi Flessner
- 01:24:38for vice chair from STEC. The other
- 01:24:41topics and this is something we're going to be dedicating our
- 01:24:45next NDSWG meeting December 17th
- 01:24:49to disclose the NPRR we
- 01:24:54have we have talked a little about this
- 01:24:58last couple of meetings and we are planning to dedicate and
- 01:25:03hopefully our discussion
- 01:25:06on this topic. Any questions?
- 01:25:16Thank you for taking up NPRR1234. I know
- 01:25:19ERCOT's very interested in trying to move it forward. So thank you
- 01:25:23for having a meeting dedicated to that and trying to get
- 01:25:27to some resolution. So thanks
- Item 13 - Combo Ballot - Vote - Katie Rich01:25:31again. I think that will take us all to our combo ballot.
- 01:25:34Erin, if you want to pull that up so we can have everyone take
- 01:25:39a look at that before we do our vote.
- 01:25:55So we have three items that would move forward as a result.
- 01:25:59PGRR117 we approve that IA NPRR1257 and then the related NOGRR dealing with the RRS
- 01:26:05limits and the others are
- 01:26:09referrals to DWG, IBRWG and
- 01:26:13PLWG. So if
- 01:26:16everyone is OK with these, I'd be looking for a first and
- 01:26:20a second before we're able to vote.
- 01:26:24This is Cyrus Reid. Happy to make the motion.
- 01:26:30Thank you, Cyrus. Anybody want to second it for him?
- 01:26:33Alex all right, we'll credit you with the second.
- 01:26:38Okay. Erin, I will turn it over to you.
- 01:26:42Thank you. Katie so beginning with the consumers.
- 01:26:52Cyrus yes.
- 01:26:55Mike yes,
- 01:26:59thank you. Mary Ellen for Nabaraj
- 01:27:08yes, thank you.
- 01:27:13Cooperatives Barry yes, thank you.
- 01:27:16Sandeep yes, thank you.
- 01:27:20Paul yes.
- 01:27:24Chris yes.
- 01:27:29Chris yes.
- 01:27:34Independent generator Chase Yes.
- 01:27:41Correct. Yes.
- 01:27:44Alex yes.
- 01:27:48Katie yes, thanks. Erin Independent
- 01:27:54power marketers okay, quick call for
- 01:27:58Ian. I don't believe he's with us. Ian,
- 01:28:01are you on the phone?
- 01:28:05Yeah, I don't think he's joined us today. I think he's
- 01:28:09on vacation this week. Okay,
- 01:28:12good to know. Thank you. Shane for Resme yes,
- 01:28:17thank you. Adam. Yes.
- 01:28:28Okay. Independent Rep. Kevin. Yes,
- 01:28:33thanks. Chris for Jennifer Yes.
- 01:28:38Chris. Yes, thanks.
- 01:28:42Ming. Yes.
- 01:28:47Investor owned utilities, Ether. Yes.
- 01:28:53West yes. Thank you,
- 01:28:58Chris.
- 01:29:04Chris Garete,
- 01:29:07can you hear me? I can,
- 01:29:12yes. Thank you.
- 01:29:15Matthew yes.
- 01:29:21Municipals Kenneth yes.
- 01:29:26Matt yes.
- 01:29:33Imane. Imane
- 01:29:47are you with us? I think you're on the phone.
- 01:29:54Okay, I see your yes in the chat. Thank you.
- 01:29:58Cody for Chris Yes.
- 01:30:02Okay. The motion carries with all
- 01:30:05in favor.
- Item 10.4 - Break01:30:11Thank you, Erin okay, why don't we do this? Let's take
- 01:30:14a quick little 10 minute break, then we'll finish
- 01:30:19the working groups in our other business. So we'll come back
- 01:30:22at 11:10. Thank you.
- 01:30:55If you see it there, know that it is.
- 01:35:16So add it to the love list. Did you know that this video of Dr.
- 01:35:19Se is removed from the Internet for what he exposed about men's health?
- 01:35:24Large company that sells blue pills. Don't want you to see this.
- 01:35:29Just saw something on here that I think all the lady.
- 01:35:34Texas. A federal court has just ruled the Corporate
- 01:35:37Transparency act, the law that says you need to file a BOI
- 01:35:40report to the federal government for llc. It's now a constitution
- 01:35:44law is no longer the law of the land is ruled unconstitutional
- 01:35:48and that applies to everyone. This case is different than the Alabama
- 01:35:52case six months ago that said transparency act is unconstitutional.
- 01:35:55But that case only applied to the whitest.
- 01:35:58Funny.
- 01:41:30All right, Everybody, it is 11:10. So let's come
- 01:41:34back to our agenda.
- 01:41:39Erin, if you want to pull that up, I believe that takes us
- 01:41:42to the voltage profile
- 01:41:46working group.
- 01:41:54There we go. Thank you so much. Can you all hear me?
- 01:41:59You're a little faint on my end.
- 01:42:02All right. I try to get closer. Is this any better?
- Item 14 - Voltage Profile Working Group - VPWG - Maribel Khayat01:42:05Yeah, go ahead. All right, I have a short update.
- 01:42:09We held a meeting this past November.
- 01:42:12Can we go to the next slide? We did not have any voting items
- 01:42:16in the agenda. We did issue updated
- 01:42:20winter spring voltage profile that has been official since
- 01:42:24December 1st. We received a market notice on that.
- 01:42:27We did not have a generator report performance report for
- 01:42:31this month. We did
- 01:42:34initiate a VPWG procedure manual before finalizing before the
- 01:42:38end of the year. We had a few discussions on IBR
- 01:42:41voltage control challenges and we did vote
- 01:42:45on leadership changes. So as of next year, we will have Weiwei
- 01:42:49from AEN and Scott from Oncor being chair
- 01:42:52and vice chair of the group. And that's it.
- 01:42:59Thanks for your update. Appreciate it.
- 01:43:08Next, that will take us to IBRWG.
- 01:43:25Great. Hi, everyone. Can you hear me?
- Item 15 - Inverter Based Resources Working Group - IBRWG - Julia Matevosyan01:43:29Yeah, go ahead, Julie. All right, so we
- 01:43:34met on November 15th.
- 01:43:38We have this item on discussing
- 01:43:42PFR performance under deep curtailment for
- 01:43:46IBRs. We started with that item in October already
- 01:43:50and had another IBR manufacturer
- 01:43:55come and talk about limitations that they
- 01:43:59have. So, yeah, basically they confirmed
- 01:44:03similar findings that Vestas bro brought up before
- 01:44:07that there is some sort of minimum technical limit
- 01:44:13for wind resources below
- 01:44:17which the IBR performance is deteriorated
- 01:44:20and kind of is not. It's not possible to perform
- 01:44:23in a similar manner as above this limit.
- 01:44:28And then we had Nick Miller from
- 01:44:31Hickory Ledge. He's a consultant, former GE
- 01:44:36employee. So he has a lot of experience with wind turbines,
- 01:44:40with wind turbine technology. So he came and he just talked
- 01:44:44from, like, physical perspective. What's causing this limit,
- 01:44:48why this limit is there. So I think he did really good job just clarifying
- 01:44:53why operation below this limit, performance below
- 01:44:57this limit for PFR is not possible.
- 01:45:01Let's go a little bit more down.
- 01:45:06And then yeah, this morning you already heard about this
- 01:45:11NOGRR and PGRR. So Sunwook at that time
- 01:45:14just provided an update of where the documents are at and
- 01:45:18kind of what are the next steps. I think we covered this
- 01:45:22this morning and then we had SPWG
- 01:45:26IBRWG coordination item and that
- 01:45:29was about multiple right through capability
- 01:45:34of IBRs and then auto
- 01:45:37reclosing schemes that transmission owners are
- 01:45:40using. And if there is any way to coordinate between
- 01:45:43this auto reclosing strategies and IBR multiple
- 01:45:48right through capabilities to kind of achieve better performance for IBRs.
- 01:45:53And so Mark McChesney who is a
- 01:45:57vice chair of SPW, a chair of SPWG, he brought a
- 01:46:01survey that they did between TDSPs. They only received five
- 01:46:05responses, but these were larger TDS.
- 01:46:09Basically conclusion here is that this auto reclosing strategies
- 01:46:13are on more site specific. So there is no common,
- 01:46:17you know, settings that are used across one TDSP or across
- 01:46:21ERCOT. And so basically what comes out of
- 01:46:25this is that needs to be a coordination between IBR plant
- 01:46:29developers. So interconnecting entities and TDSPs
- 01:46:34and discussion needs to happen to understand what are auto reclosing
- 01:46:37strategies around this ibr. So including the line
- 01:46:40that connects IBR to POI but also adjacent
- 01:46:45lines. And so what we ended up with
- 01:46:49right now is to coordinate with resource integration team at ERCOT
- 01:46:53and see if just kind of a language about this
- 01:46:57coordination, a need for this coordination can be included in resource
- 01:47:02integration handbook. So we're still talking about this. We didn't
- 01:47:05get resolution yet, so we
- 01:47:09should keep this item still open. And ROS,
- 01:47:12you know, list of items, but we'll probably close it soon.
- 01:47:16And the last one I brought NERC and other
- 01:47:20industry updates. So I think important one here is miso,
- 01:47:24they presented kind of similar proposal for grid forming
- 01:47:29for battery storage. So they process is basically
- 01:47:33is done. They are in the process of implementing
- 01:47:37the language for grid forming requirements into the
- 01:47:40business practice manual. So it's basically accepting red lines and
- 01:47:44releasing the black line document that will go in force in
- 01:47:49January. And so basically grid forming requirement will be applied to all
- 01:47:52future batteries going forward from the next cycle
- 01:47:56of the generation interconnection studies. So they do inject generation connection
- 01:48:00in cycles as a groups.
- 01:48:04And so the next group coming up is from 2023
- 01:48:08application period. And so
- 01:48:11batteries in the cycle will be studied with those grid
- 01:48:15forming requirements in mind and
- 01:48:19then we can scroll a little bit down. I think this whole
- 01:48:23page is on grid forming. Yeah, so this nerc,
- 01:48:27I think this is important too. So three NERC standards basically
- 01:48:31now went to FERC. They've been developed, approved in NERC
- 01:48:34stakeholder process and now filed with FERC following
- 01:48:39up on order 901. So this is PRC-028
- 01:48:42which is data collection data
- 01:48:46measurement standard. PRC-029 is right through standard for IBRs
- 01:48:50and PRC-030 is when disturbances are
- 01:48:54happening at generation plants. The plant is
- 01:48:57supposed to do root cause analysis and follow up and
- 01:49:01develop mitigation. So this is what that standard is about.
- 01:49:05And these are all NERC standards. So these are all will apply in ERCOT as
- 01:49:09well. Even though it's a following up on 4 quarter 901 and
- 01:49:15they start a new milestone which will be focused on modeling.
- 01:49:21And so there are a number of projects already opened for this
- 01:49:24and NERC will hold technical workshop on January 15th
- 01:49:28and 16th and
- 01:49:32yeah, so and then there are just couple of related
- 01:49:37to IBR performance events where I
- 01:49:41linked up, you know presentations that are happening that are relevant. So deleted
- 01:49:45links are all here if you are interested to see.
- 01:49:48And this is all we had. And the next meeting is on Friday.
- 01:49:53Next Friday. Thanks Julia.
- 01:49:57Thanks for the update that
- 01:50:07will take us to SPWG.
- 01:50:29Can you go ahead and advance to the next slide?
- Item 16 - System Protection Working Group - SPWG - Mark McChesney01:50:37Thank you. So the Last meeting was November 5,
- 01:50:402024. We did have a leadership election where I was nominated again
- 01:50:43for to continue as chair in 2025
- 01:50:47and we nominated Jordan Watkins of Centerpoint Energy as Vice chair.
- 01:50:51We also received updates from Texas RE regarding this operation
- 01:50:55statistics through Q2 of 2024.
- 01:50:58We also received some updates on the NERC PRC activities and
- 01:51:02standards updating. As Julie just mentioned, we reviewed
- 01:51:06an IBR reclosing survey and practices. So within
- 01:51:10in relation to the ROS action item for our two groups.
- 01:51:14SPWG put up a survey to its members to
- 01:51:18kind of get a feel of what the IBR reclosing practices
- 01:51:22were across the ERCOT territory. We did get a very limited response
- 01:51:26and not a consistent answer. So that's why you
- 01:51:30know, we also discussed some of the suggestions
- 01:51:36in IEEE 2800 around the number of free closes or number
- 01:51:40of fall ride through events that an IBR was expected to ride through
- 01:51:44as well as the maximum phase angle jump that
- 01:51:47an IBR would ride through to take those numbers
- 01:51:52into account. As we look at reclosing around IBRs not only
- 01:51:56in the the tie line to the IBR but also lines adjacent to
- 01:51:59it. Then we
- 01:52:03reviewed the case build statistics between the steady
- 01:52:06state working group case and the short circuit model. And then we
- 01:52:10had a presentation on IBR challenges focused
- 01:52:13on the lack of negative sequence current injection and some experiences
- 01:52:17that we've had as with end to end testing
- 01:52:21and failure of directional elements due
- 01:52:24to the lack of negative sequence injection. That's a concern when applying
- 01:52:29phaser based protection around IBRs. So that
- 01:52:33was the conclusion of our meeting and I'd be happy to take any questions if
- 01:52:36there are any.
- 01:52:40Thanks, Mark. I appreciate your update and your continued
- 01:52:44leadership. So looking forward to working with you next year.
- 01:52:53We have one more working group, Sunny State Working group.
- 01:53:01Hi, good morning everyone. Are you able to hear me?
- Item 17 - Steady State Working Group - SSWG - William Robertson01:53:05We can go ahead. All right, so our November
- 01:53:08meeting was pretty short. So just the two main topics to talk about
- 01:53:12now that we had finished both of our case builds for this year. We went
- 01:53:16over the 2025 transmission loss factor. So TSPs
- 01:53:19have been submitting and verifying the data that ERCOT provided to the working group
- 01:53:23and we should be able to have all of
- 01:53:26that information given to ERCOT by today. Was the due date for
- 01:53:29that. Also the other topic that we went over was our
- 01:53:33calendar for next year with all of the due dates and
- 01:53:36expected timelines for the 2025 SSWG
- 01:53:40case building process. So that's
- 01:53:44essentially the main topics that we covered in our meeting for November. Is there
- 01:53:48any questions on that?
- 01:53:54Don't see any questions. Thanks so much for your update.
- 01:53:58Thank you.
- Item 18 - Other Business - Katie Rich01:54:05All right, that will take us to down to other
- Item 18.1 - Review Open Action Items List01:54:09business. And I wanted to go through the
- 01:54:13open action items list one more time.
- 01:54:33Julia, I believe on this first one you reported that you were
- 01:54:37still working on this at iprwg. Is that correct?
- 01:54:40Yes. Okay. We're close to finish, but not yet.
- 01:54:44Okay. And then I
- 01:54:48think with NDSWG they reported they are still working on the
- 01:54:51ICCP handbook.
- Item 18.2.3 - Operations Training Working Group OTWG01:54:58And then I think we were hoping to hear back on OTWG about
- 01:55:02the NEXSTART resources. I don't know if anyone's on the line that
- 01:55:06can speak to that one.
- 01:55:20Okay. And then PLWG, we got an
- 01:55:24update on that. Dylan, thank you for working on that one.
- 01:55:29And then I believe the on the EPA regulations,
- 01:55:34we'll keep that on here. I mean it's more of a coordination with WMS
- 01:55:38and I know that on the WMS side, WMWG is
- 01:55:42planning to have a discussion at their January
- 01:55:4630th meeting about this.
- 01:55:50One of our experts will be speaking on that meeting.
- 01:55:53So we will leave this item here and
- 01:56:03then on this TAC assignment,
- 01:56:07I think we talked about this last time. I think,
- 01:56:10you know, we, we feel like this issue has been resolved
- 01:56:15by everything that's going on with the other
- 01:56:18law, large loan issues like NPRR1238.
- 01:56:23So I think I can report to TAC that,
- 01:56:27you know, this assignment will be complete with
- 01:56:32NPRR1238 if
- 01:56:36we want to make some sort of notation about that one.
- 01:56:41Katie, I'm still hesitant to remove that until we get
- 01:56:45some clarity from ERCOT on what their proposal
- 01:56:49is for their comments for 1238. This is.
- 01:56:53Oh, good point, Chris. Yeah, yeah. And as
- 01:56:57golden spread, we're frustrated with ERCOT right now because we haven't had answers
- 01:57:00in six months on this. It's been sitting. So we'd like
- 01:57:04to keep this there as another option because,
- 01:57:08like I said, there has been no, no communication
- 01:57:12whatsoever. We've reached out to ERCOT individually and we've
- 01:57:16tried to do that through the working groups and we're getting nowhere. So we're
- 01:57:19almost to the point where we're ready to move forward without ERCOT comments,
- 01:57:23but we're trying to be as diplomatic as possible.
- 01:57:27Yeah, Chris, I appreciate that. I'm sorry, maybe what I
- 01:57:31should have said is if we can just maybe
- 01:57:35put something in the update that we're kind of waiting. What happens
- 01:57:39with NPRR1238. That way
- 01:57:42it looks like, you know, we've taken this TAC assignment seriously.
- 01:57:49Thank you. Yeah, thank you.
- 01:58:24Thanks, Susie.
- 01:58:28On the next one, on the September 60E2 event,
- 01:58:32I feel like our work is completed on that.
- 01:58:36I feel like we've seen the revision
- 01:58:40requests associated with that this year. So I would probably just
- 01:58:44report back to TAC that I feel like this item is largely completed
- 01:58:48unless anyone disagrees.
- 01:59:05Okay, thank you, guys. And then Susie
- 01:59:08helped me significantly on this parking lot item issue.
- 01:59:13If you want to scroll down so we can see those items,
- 01:59:18my understanding is the only item
- 01:59:22left is the Black Start service, which is
- 01:59:25that Black Start working group.
- Item 18.2.1 - Black Start Working Group - BSWG01:59:29So there's a couple of different things we could do.
- 01:59:33We could keep just that item as an open
- 01:59:37action item, and then that would allow us to
- 01:59:42clear the deck on this parking lot item.
- 01:59:46I wanted to see if folks had any thoughts on
- 01:59:50this.
- 02:00:00Yeah, go ahead, Freddie. Yeah, thanks,
- 02:00:03Katie. Yeah, this is, this is definitely on the BSWG and
- 02:00:07ERCOT's radar. We are hoping
- 02:00:11to get more work done on this next year.
- 02:00:14But I do agree it makes sense to keep this on
- 02:00:19the list. So however,
- 02:00:22however ROS wants to do that. I'M I'm okay with.
- 02:00:25Yeah, but it's. It is com. You know, help me confirm
- 02:00:30this. It's just. It's really just the Black Start service. Right.
- 02:00:34Yeah. Correct. How we want to utilize esrs
- 02:00:38in. In blackstart.
- 02:00:44How about we make that an open action item for blackstart
- 02:00:47working group, and then, yeah, we can kind of strike the rest of this.
- 02:00:51I think we're trying to move away from parking
- 02:00:55lot items anyway, so I think if it was just a direct assignment to BlackStart
- 02:00:59Working Group, that might give us more visibility.
- 02:01:46Thanks, Erin. I think that. I think that works.
- 02:02:12All right. That looks good to me. We want to save
- 02:02:17these so we can have the updates.
- 02:02:21And I will put last couple items
- 02:02:25in my update to TAC or
- 02:02:28are for the January meeting.
- 02:03:01Okay. Thanks, Erin.
- 02:03:09Right. And then just a couple things that aren't on the agenda.
- 02:03:13I wanted to thank all of the working group
- 02:03:16leadership for all of their hard work this year.
- 02:03:20I know we've had some particularly many technical
- 02:03:23issues, so we couldn't have done it without you. I just
- 02:03:27really wanted to thank Alex for serving as my vice
- 02:03:31chair this year and just helping the meetings run smoothly
- 02:03:35and just helping behind
- 02:03:38the scenes to help with all the prep work that goes into preparing
- 02:03:42for each of these on a monthly basis. And I
- 02:03:46look forward to working with many of you guys next year.
- 02:03:50And Susie and Erin, thank you so much for helping
- 02:03:54to keep us straight and make sure the meetings are moving efficiently.
- 02:03:59And happy holidays to everyone.
- 02:04:02If I don't see you before the next couple of weeks.
- Item 19 - Adjourn - Katie Rich02:04:07Thanks again. And if there's nothing else, then we.
- 02:04:10We can adjourn.
