SHORT DESCRIPTION: Partial Implementation Details of NPRR987
INTENDED AUDIENCE: All Market Participants
DAY AFFECTED: October 14, 2022
LONG DESCRIPTION: On October 14, 2022, Protocol language associated with Nodal Protocol Revision Request (NPRR) 987, BESTF-3 Energy Storage Resource Contribution to Physical Responsive Capability and Real-Time On-Line Reserve Capacity Calculations will be partially implemented. Specifically, NPRR987 related changes in Nodal Protocol Section 126.96.36.199, Ancillary Services Capacity Monitor, will be implemented.
Following the implementation of this change, the Physical Responsive Capability (PRC) calculation will account for contributions from Energy Storage Resources (ESRs). The PRC-related changes are applicable during both the current “combo model” era for ESRs (where ESRs are modeled as a combination Generation Resource and Controllable Load Resource) and the future “single model” era.
The remaining Protocol language related to NPRR987 will be implemented at a later date.
ADDITIONAL INFORMATION: Pursuant to Nodal Protocol Section 21.6, Nodal Protocol Revision Implementation, ERCOT is required to provide notice as soon as practicable, but no later than ten days prior to implementation.
NPRR987 and associated documents can be found on the ERCOT website.
