NOTICE DATE: April 1, 2021

NOTICE TYPE: M-F022621-03 - General

SHORT DESCRIPTION: Reminder - Implementation Details of NPRR971, NPRR986, NPRR1043, and VCMRR027

INTENDED AUDIENCE: All Market Participants

DAYS AFFECTED: April 2, 2021

LONG DESCRIPTION: On April 2, 2021, Protocol language associated with Nodal Protocol Revision Request (NPRR) 971, Replacing the Real-Time Average Incremental Energy Cost; NPRR 986, BESTF-2 Energy Storage Resource Energy Offer Curves, Pricing, Dispatch, and Mitigation; NPRR 1043, Clarification of NPRR986 Language Related to Wholesale Storage Load (WSL); and Verifiable Cost Manual language associated with Verifiable Cost Manual Revision Request (VCMRR) 027, Related to NPRR986, BESTF-2 Energy Storage Resource Energy Offer Curves, Pricing, Dispatch, and Mitigation, will be implemented.

NPRR971 introduces the following changes to the Nodal Protocols:

NPRR986 and NPRR1043 introduce the following changes to the Nodal Protocols for Energy Storage Resources (ESRs) in the combo model era:

VCMRR027 deletes Section 2.2, Exceptions for Energy Storage Resources, and Appendix 10, Procedure for Evaluating Costs and Caps for Energy Storage Resources, to align the Verifiable Cost Manual with the Nodal Protocol changes addressed in NPRR 986 that state an ESR is not allowed to submit verifiable costs and will have their MOC set to the SWCAP.
