NOTICE DATE: September 30, 2022
NOTICE TYPE: M-C093022-01 NPRR
SHORT DESCRIPTION: Notice regarding provision of Non-Spinning Reserve Service from ESRs and Implementation of NPRR1096
INTENDED AUDIENCE: Market Participants
DAYS AFFECTED: October 4, 2022
LONG DESCRIPTION: Nodal Protocol Revision Request (NPRR) 1096 requires Resources that provide ERCOT Contingency Reserve Service (ECRS) to limit their responsibility to a quantity of capacity that is capable of being sustained for two consecutive hours and Resources that provide Non-Spinning Reserve Service (Non-Spin) to limit their responsibility to a quantity of capacity that is capable of being sustained for four consecutive hours. ERCOT is in the process of implementing the Non-Spin- related NPRR1096 changes as part of the December 2022-R6 release, which is scheduled between December 6 and 8, 2022. Specifically, changes in Nodal Protocol Sections 2.1, 3.17.3, and 126.96.36.199 will be implemented as a part of the R6 release.
ERCOT is concerned that, until these Non-Spin-related changes take effect, allowing Energy Storage Resources (ESRs) to carry Non-Spin could present a reliability risk because, if committed and deployed, they may lack the capability to provide the needed power output for a sufficient duration. Given ERCOT's duty to ensure system reliability under Texas Utilities Code § 39.151(a)(2) and 16 Texas Admin. Code § 25.361(b), ERCOT has determined that it must prohibit all ESRs from providing Non-Spin until the system and procedure changes associated with the provision of Non-Spin under NPRR1096 are developed and implemented later this year. Consequently, effective Operating Day October 4, 2022, the qualification of ESRs to provide Non-Spin will be terminated.
To provide Non-Spin after NPRR1096 implementation, an ESR--including any ESR currently qualified to provide Non-Spin--will need to be qualified to provide Non-Spin under updated criteria based on NPRR1096's requirements. Effective immediately, ERCOT is accepting requests from ESRs to qualify for Non-Spin per NPRR1096 criteria.
ACTION REQUIRED: Any QSE that wishes to qualify Resources to provide Non-Spin, including ESRs, may submit a request for qualification by contacting its Account Manager.
