<ul>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Floyd expressed concerns with existing language in Section 9.2.5, stating it mixes interconnection equipment specifications with operational instructions.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Floyd recommended amending the language to either remove the phrase 'capable of being operated remotely to comply with an instruction from ERCOT' or allow for a disclaimer ensuring safety and communication protocols.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">ERCOT's Agee Springer disagreed with Floyd, arguing the current language only requires equipment capability without specifying operational protocols and cited August comments as addressing safety and communication concerns.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Martha Henson from Oncor supported ERCOT's stance, mentioning that large loads typically have remotely controlled disconnect devices and addressed critical load notifications are covered by Oncor's existing tariffs.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Floyd acknowledged the remote control provision wasn't the main issue but focused on language that might imply ERCOT's instructions override safety exceptions.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">A discussion ensued on finding compromise language that maintains safety protocols without unnecessarily complicating planning guides.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">The group deliberated on finding a base document to build from, considering comments from Oncor, joint TSP comments, centerpoint comments, and ERCOT comments.</span></li>

<ul>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Kristin Cook from Southern Power presented comments on PGRR120, suggesting potential improvements in the language.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Cook proposed two main changes: clearer communication to stakeholders engaging in project interconnections, with a reference to section 5.3.1 regarding security screening, and adjustments for existing generators to modify without losing SSO mitigations.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">The intent of the first change is to provide more certainty to generator owners currently far along in the interconnection process.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">The second change would allow existing generators to modify if SSO has already been fully mitigated, alleviating potential disincentives.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Freddy Garcia from ERCOT Operations acknowledged the comments and requested time to thoroughly review them, proposing to revisit the matter in January.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Sunil Dhakal from Lone Star Transmission expressed disagreement with the blanket ban implied by the PGRR, as it does not allow for SSR mitigation or identification of susceptibilities to SSO events.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">The discussion also focused on reliability concerns and difficulties in mitigating these complex problems, with ERCOT emphasizing reliability as a priority.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">ERCOT is open to further discussions with Lone Star and other stakeholders regarding concerns.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">The PLWG agreed to table the item for further discussion.</span></li>

<ul>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Jeff Billo from ERCOT Operations gave a presentation on agenda item PGRR122, which was also presented at DWG the previous week.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">The discussion centered on the Southern Cross (now Southern Spirit) DC tie project and related reliability performance criteria.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">The Public Utility Commission (PUC) issued directives, including Directive 9, which required ERCOT to study ancillary services for the project.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">ERCOT's studies indicated that losing over 1400 megawatts of demand could lead to frequency excursions and potential generator trips under certain conditions, especially low inertia.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">In response to these findings, ERCOT filed and got approval for NPRR1034 to limit DC tie exports to ensure frequency stability.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Implementation of NPRR1034 is on hold until the project construction is complete.</span></li>

<ul>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Protocol definition of 'load' shared: amount of energy in megawatt hours delivered at a specific point or points in a system.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Discussion referenced PGRR107, where distinctions between capital 'L' and lowercase 'l' loads were made.</span></li>

<ul>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Objective was to distinguish when 'load' should be capitalized as it relates to defined terms, and make appropriate changes.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">The recent workload had delayed progress on this task, but efforts are now underway to make updates.</span></li>
