The NOGRR245 deadline to submit extension or exception requests was moved to April 15, 2025.
Existing units must complete maximization by December 31, 2025.
Different deadlines for frequency and voltage ride-through extensions: frequency by December 31, 2027, and voltage by December 31, 2028, depending on ERCOT granting the extension.
ERCOT is currently validating and reviewing submitted data and will develop a scope for the exception process by July-August 2025.
NOGRR245 exception studies are planned for September-October, with notifications in November-December 2025.
The exemption process timeline might adjust based on rulemaking from the PUC and the number of submissions received.
Incomplete submissions must be addressed within ten business days upon notification from ERCOT.
ERCOT's decision on extension requests to come within 180 days, with options to notify of extended review timelines if necessary.
Participants can appeal ERCOT's decisions to the PUC.
Approximately 500 resources intended for maximization by December 31, 2025, with various extension and exemption requests noted.
Obligations for resources not submitting exception/extensions by April 15 include meeting frequency and voltage ride-through requirements by December 31, 2025, or synchronization/operation dates.
Clarification that requirements apply only to transmission connected resources, not distribution connections.
Discussion on the importance of submitting a proposed modification request before changing field settings, following ERCOT's Planning Guide 5.5(6).
Introduction of the updated dynamic model template, due for submissions starting June 1, 2025.
Focus on issues with interconnecting entities selecting power plant controllers late in the process, causing problems if the controller does not pass MQT tests.
Announcement that starting next week, entities must declare their power plant controller when submitting a model.
Clarification that models submitted and accepted without declaring a power plant controller won't need updates, but any new submissions must include this information.
Emphasis on the potential need for restudy if declared models differ significantly from earlier submissions.
Discussion on the importance of ensuring the power plant controller can pass all required tests and matching the declared performance in later stages.
Concerns raised on communication delays affecting the dynamic reactive response of power plant controllers.
Highlighting the need for accurate PSCAD modeling accounting for data measurement and command update constraints.
Consideration of disallowing generic models in PSCAD due to their limitations in accurately reflecting site-specific constraints.
Encouragement of accurate submissions taking into control speeds and communication lags.
May 1 QSA deadline: All requirements must be met by May 1, 2025. The 45-day deadline for projects is March 17.
EPS meter design proposal needs to be submitted before ERCOT approves full registration data. This affects projects aiming for future production load dates.
New EIA reporting requirement: ERCOT must submit EIA-930A, detailing generator inventory. Three new EIA fields will be added to RIOO-IS and RIOO-RS starting April 24, 2025.
EIA fields: Recommended completion before full registration data approval for projects without approved production load dates. Proposing mandatory inclusion in registration glossary revision.
Clarification on procedures: EPS meter design proposal must be submitted 90 days before production workday, not just prior to PLD.
Discussion on EIA-860 form: Completion depends on certain criteria, such as SGIA assigned notice to proceed.
NPRR1272: Update on voltage support and private use network revision request.
Commissioning requests for parts 1-3 must be submitted to the designated commissioning request inbox.
There are over 2,000 generation interconnection requests totaling about 405 gigawatts. Small generation consists of 26 non-model ready and 50 model-ready projects.
