<ul>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">ERCOT's November 2024 unofficial peak demand was recorded at 60,170 megawatts, an increase of 3,635 megawatts from November 2023.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Three OCNs were issued in November: one for a topology change in the Panhandle IROL region, and two anticipating possible future emergency conditions.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">A new PVGR penetration record of 44.17% was set on November 20th at 14:55.</span></li>

<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">Grid Reliability and Resilience Assessment Report</span></li>
</ul>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">ERCOT will hold an EHV 765 workshop on January 27th to discuss the 765 plan.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">The new Grid Reliability and Resilience Assessment Report is a requirement from Senate Bill 1281, and ERCOT is required to perform this assessment every other year.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">The assessment studied two extreme weather scenarios:</span></li>
<ul>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">A winter peak scenario similar to the 2021 Uri storm</span></li>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">A Category 5 hurricane scenario hitting Houston</span></li>
</ul>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Findings suggest that transmission enhancements are needed to reduce load loss and prevent system cascading events.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">For the winter peak scenario, ERCOT found a need to enhance import paths to Central Texas and between South Dallas and Central Texas.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">For the hurricane scenario, substation hardening is crucial in reducing the impact on the Texas grid and consumers.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Ping Yan suggested that results could be further discussed in the January RPG meeting.</span></li>

<ul>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Fred Huang from ERCOT discussed NOGRR272 and PGRR121, focusing on large amounts of IVRs on the grid and stability challenges.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Talked about solutions for stability issues, including synchronous condensers and inverter-based resources.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Discussed the development of advanced grid support capabilities for batteries with benefit studies beginning in 2023.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Mentioned NERC's two white papers on grid forming technology and specifications for grid forming batteries.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">ERCOT is working on a testing framework with engaged electronics to adopt this technology, forming the basis for NOGRR and PGRR.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Outlined benefits of grid forming technology such as transient dynamic voltage and frequency response improvements.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">ERCOT noted no additional hardware or overload capacity is required for these requirements, fitting within planned equipment ratings.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">No energy market dispatch changes are required under the current proposals.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">NOGRR provides a high-level requirement definition, while PGRR adds modeling details.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">ERCOT is working on a DWG procedure manual update to include the testing framework, anticipating discussion in February.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">All tests are simulation-based with no envisioned physical commissioning tests.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Implementation timelines are flexible, with ERCOT working with stakeholders on reasonable dates.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Some projects in weak grid areas are adopting advanced grid support capabilities before official approval.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Fred Huang provided a global update on grid forming capabilities with examples from other system operators and manufacturers.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Discussion included procurement strategies, e.g., Hawaii's competitive RFP process for grid forming batteries.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Inertia markets were mentioned; ERCOT sees stable inertia levels, with benefits seen in weak grid scenarios.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Michael Jewell raised timelines issues comparing European and proposed ERCOT timelines.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Manufacturers will be invited to present on their advanced grid forming capabilities and related challenges.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Coordination between IBRWG and DWG was discussed with testing frameworks and procedure manual updates in progress.</span></li>
</ul>
<h3><strong>Next Steps</strong></h3>
<ul>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Continuing to discuss and refine PGRR and NOGRR requirements at IBRWG meetings.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Inviting manufacturers for discussion on January 17th on capabilities and limitations.</span></li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Coordinating a DWG and IBRWG session in February for further testing framework review.</span></li>
