ERCOT stakeholders have endorsed changes to the grid operator's ancillary services methodology as part of the annual process to determine the minimum amount of products that will be procured in 2025.

Texas RE staff said their upcoming risk assessment will identify multiple ongoing challenges to grid reliability.

The PJM Markets and Reliability Committee discussed soak time modeling, primary frequency response, and the RTO's work to update its credit rules.

A summary of the issues scheduled to be brought to a vote at the PJM Markets and Reliability and Members committee meetings Jan. 23, 2020.

PJM’s Operating Committee put manual revisions for its gas contingency rules on the fast track to endorsement after approving the changes on the first read.

PJM’s Darlene Phillips will take over the Operating Committee after current Chair Dave Souder starts his role as executive director of systems operations.

The number of generators providing primary frequency response in 2018 fell short of PJM’s expectations, according to the RTO’s most-recently analyzed data.

ERCOT stakeholders moved to address the Texas grid’s growing pains by tweaking the system’s ancillary service offerings, which predate 2010.

PJM will spend only $162,000 to test the winter capabilities of 21 generators totaling 477 MW in 2018, RTO officials told the Operating Committee.

ERCOT members voted down the ISO’s attempt to salvage a revision request that would have replaced several ancillary services with new products.
