Congestion Management Working Group - 12/6/2024 Meeting Update JANUARY 8, 2025 ALEXANDRA MILLER, CHAIR
CRR Technology Update oUpdate provided in response to requests for more details on hardware improvements happening in parallel with auction parameter adjustments oHardware changes in April 2024: Increased Server CPUs from 16 to 28 and tuned parameters resulted in 20% performance improvement. oNo additional benefit beyond 28 CPUs with DDR4 memory due to saturation of RAM and limited multi-threading due to sequential and interlinked nature of the constraints in the problem oFuture upgrade to DDR5 memory configuration may provide another 30% improvement oProject: ERCOT Cloud Foundations establishes robust Cloud Foundation and connections ensuring secure, compliant, and optimized cloud services Expected to complete Q2 2025 oProject: CRR Tech Refresh: Upgrade Oracle DB, OS, and software; containerize CRR Apps; look at options to run LTA in Cloud with advanced hardware Start Q1 2026
CRR Long Term Auction Solution Time, Transaction Limits oGraph showing solution times across auctions with peak to unacceptable times, and recent improvements and impact of Transaction Adjustment Periods oMarket Redesign: removing multi-month product oContinuing to study impact of removing multi-month product results show best improvement in Seq 3-5 oDraft NPRR reviewed strikes multi-month strip references oPricing report to curb participation for price discovery oStaff continued working with vendor to explore pricing report concept oDraft NPRR reviewed adds pricing report for all biddable combinations and sets a 1 MW Bid Minimum (with 0.1 increments) oReminder, all CRRs in baseload are priced in each auction, report is in the CRR MUI and posted with auction results on MIS public oNew TOU super peak obligation to avoid some option bidding oCMWG will have discussion in Jan on super peak TOU concept
NTE Update Operational Concerns Related to IRR Telemetry and Curtailment Logic oMore IRRs are receiving signals to hold their basepoint due to NTE rollout. This has illuminated issues with telemetry and curtailment causing control problems oSome resources have inaccurate telemetry with incorrect Real-Time Power Potential calculations leading to manual operator actions oExamples were shared showing unrealistic HSL changes and poor curtailment logic across regions and resource type oERCOT is sending RFIs to all generators with issues. While some implemented corrective actions quickly, a majority have a lengthy expectation of time to resolution, and a few did not respond. oERCOT is asking generators to confirm accurate RTPP calculations across fleets. oDespite these issues, NTE is overall providing operational benefit.
NPRR 1214 Reliability Deployment Price Adder Fix to Provide Locational Price Signals, Reduce Uplift and Risk oERCOT staff and sponsors continuing to work on language revisions, and reviewed Draft comments are posted to the meeting page oMain changes include: oAdditional sections to fully incorporate locational adder in settlement protocols oName and variable updates to avoid conflicts in system, with subscripts added oPrice added can be both positive and negative oHub prices will be derived from the locational prices oCorrection to restore one inadvertent change made during previous edits to move implementation to post-RTC oCMWG did not have immediate concerns with this version of the draft, which is continuing to undergo ERCOT internal review
