Executive Summary
A quick, painless Protocol Revision Subcommittee (PRS) meeting. Troy gave his usual update on project statuses, still with no implementation date for FFR Advancement, which changes the ERCOT interface. Mark Ruane gave an update on securitization – a webpage with everything you need to know is at https://www.ercot.com/about/news/securitization . Three non-exciting NPRRs passed (NPRR1095 – Texas SET changes, NPRR1098 – DC Tie Reactive Power requirements, and NPRR1102 – ERCOT has discretion in non-IDR meter profiles) passed without significant incident, though there was concern on the Texas SET NPRR’s cost. Troy hinted that the budget for NPRRs may be significantly expanded in the coming few years. There was a very close vote on NPRR1092 (Reducing RUC offer floor and removing RUC Opt-out) with those wishing to delay carrying the day 52-48. There was concern about unintended consequences of NPRR1110 (New Blackstart Requirements), so that got referred to ROS and WMS. And a new NPRR (NPRR1111) that allows ERCOT to better manage renewable resources behind Generic Transmission (stability) constraints got sent to ROS and WMS as well.
Agenda
Notes
- Troy’s project update
- FFR advancement in second half of 2022, probably
- ECRS project starting in 2022
- ERCOT is looking into combining implementation of NPRR1091 and 1093
- ERCOT is still looking at survey responses about voltage reduction, and they will need to digest that before knowing when the price impact part of NPRR1105 will be implemented
- Securitization
- Disbursement of M funds is complete
- Initial credit estimates should be sent 12/20/21
- Initial invoices should be sent 1/11/22
- Template for new letter of credit form (for securitization credit) has been sent
- N NPRR should be published by the end of the month
- LSEs need to document their exposure by 12/22/2021
- New webpage with all the securitization information at https://www.ercot.com/about/news/securitization
- NPRR1095 (Texas SET 5.0 Changes) – there was some discussion about the cost about $2 million, which would be most of the annual NPRR project budget. Troy said that maybe we shouldn’t worry about that too much as it looks like the $3 million annual project budget will probably be expanded. It was endorsed on the combo ballot.
- NPRR1098 (DC Tie reactive power requirements) – endorsed on combo ballot
- NPRR1102 (ERCOT discretion for adjusting all non-interval data meters load profiles) – endorsed on the combo ballot
- NPRR1092 (Reduce RUC Offer floor and take away RUC Opt-out) – lots of discussion on this one. Those against had two main points; 1) The need for this might go away with commission action, and 2) Luminant had a resource that was Reliability Unit Committed when it had already self-committed, and (for some reason) that means this NPRR should not pass. Those for the NPRR said that this is a market power abuse concern and that the PUC’s actions will not affect that and 2) Luminant’s case happens when a resource commits in the time window after the RUC snapshot was taken by ERCOT, but before the RUC instructions are issued, and it is a known market behavior that your commitment at the RUC snapshot is the commitment that matters. Those in favor of delaying this NPRR won in a very close vote, 52-48.
- NPRR1110 (New Blackstart Requirements to four year contracts and onsite fuel requirements) – the meeting participants felt that these changes needed further review, so this was sent to ROS and WMS for further discussion
- NPRR1111 (Let ERCOT tell a intermittent resource to obey its basepoint if it will help manage a GTC) – In ERCOT today a wind or solar resource only has to obey its base point if it is being curtailed due to congestion, otherwise, if the wind picks up it is free to exceed its basepoint with no repercussions. This NPRR would allow ERCOT to tell it to obey its base point at all times (this is an OPTION for ERCOT). This would allow ERCOT to let Generic Transmission Constraints to be raised closer to their actual limits (right now they are lowered a good percentage below to allow for wind/solar overproducing) – referred to ROS and WMS on the combo ballot
