NYISO unexpectedly pulled a vote on modeling improvements for capacity accreditation from the Management Committee’s agenda, delaying further discussion until April 9.

PJM’s Markets and Reliability Committee endorsed two proposals to revise the RTO’s ELCC formula to add two new generation categories and limit the penalties resources face if their accreditation declines between auctions.

The NYISO Business Issues Committee approved, in concept, implementation of the ISO’s new firm fuel election process and requirements as part of its changes to capacity accreditation.

MISO is nearing an overhaul of its capacity accreditation methods for load-modifying resources and demand response that would be based on whether they can assist during periods of high system risk.

Among other actions, the PJM Markets and Reliability Committee and the Members Committee will consider endorsing various manual revisions.

PJM heads into 2025 with several proposals before FERC seeking to rework its capacity market and generator interconnection queue, while stakeholders work on an expedited Quadrennial Review of the market and changes to resource accreditation.

MISO said it will finalize an availability-based accreditation for nearly 12 GW of load-modifying resources over the first quarter of 2025 ahead of a filing with FERC.

Four environmental nonprofits insist MISO’s recently approved capacity accreditation is incomplete unless the RTO details how it will conduct its loss of load modeling the new approach relies upon.

FERC authorized MISO’s move to a capacity accreditation method that blends probabilistic availability with historical unit performance.

NYISO stakeholders raised concerns about the way the ISO values transmission security at the Installed Capacity Working Group.
