MISO said it will push back a contentious filing for a new, marginal approach to capacity accreditation into early next year.
ERCOT expects normal grid conditions during Saturday’s solar eclipse when solar resources will see their output reduced.
ERCOT surprised market participants with an announcement that it plans to increase operating reserves by requesting an additional 3,000 MW of capacity to shore up the grid for the upcoming winter.
A call for FERC to run a technical conference on capacity accreditation ran into a mixed reception, with the ISO/RTO Council saying it is too regional of an issue for the idea to have an impact.
Doubts continue to swirl around which version of MISO’s future fleet mix is appropriate for long-range transmission planning — the Independent Market Monitor’s or the RTO’s itself.
Senior executives from all seven ISO/RTOs discussed how the changing resource mix is impacting reliability.
PJM's Board of Managers has adopted a variant of the RTO annual capacity market CIFP proposal, which includes changes to risk modeling, accreditation and capacity performance.
PJM members recommended various avenues for the RTO's Board of Managers to consider as it weighs a possible FERC filing incorporating components of proposals made during the critical issue fast path process.
