Settlement Point retirement process Oklaunion Auction impacts Monthly auctions: OKLA_OKLA_G1 will be biddable in all monthly auctions through the 2022.JUN.Monthly.Auction But, OKLA_OKLA_G1 will be non-biddable in all subsequent monthly auctions beginning with the 2022.JUL.Monthly.Auction Long-term auctions: OKLA_OKLA_G1 will be biddable in all long-term auctions covering 2020, 2021, and the 1st half of 2022 The last biddable auction will be the 2022.1st6.AnnualAuction.Seq1, which won t take place until October 2021 But, OKLA_OKLA_G1 will be non-biddable for all long-term auctions covering the 2nd half of 2022 and beyond No CRRs will be sold on this point with an effective date after June 2022 4 PUBLIC
Settlement Point retirement process Oklaunion CRR team process Approved Network Operations Model Change Requests (NOMCRs) are applied to the associated CRR Network Models automatically through the model building tools But, the NOMCRs can only be submitted for review within 1 year of the effective date of the change As a result, the CRR team can t submit a NOMCR to retire OKLA_OKLA_G1 until July 2021 Until the submitted NOMCR is automatically picked up by the model building tools, the CRR model builder must manually make OKLA_OKLA_G1 non- biddable for the appropriate future long-term auctions The CRR team is typically tracking 5 10 retiring Settlement Points for which manual processes must be completed during the model build 5 PUBLIC
Settlement Point retirement process Oklaunion Process improvements from NPRR1017 The 6-month timeframe for retiring Resource Nodes proposed in NPRR1017 would allow the CRR team to submit the NOMCR to retire the Settlement Point immediately after the retirement date has been verified This would eliminate the manual process of making a retiring Settlement Point non-biddable for future long-term auctions This would also help the ERCOT Network Modeling team coordinate with Resource Entities (REs) and Transmission Service Providers (TSPs) on the removal of equipment associated with retiring Settlement Points And, all ERCOT market models would remove the Settlement Point and all associated equipment quicker and would be able to better align with what is really active at that location This would remove the concerns of ERCOT Operations that unnecessary action may be taken to address equipment that is modeled but isn t actually active 6 PUBLIC
