NYISO announced that the state broke its hourly wind generation record Sunday, generating 1,939 MW from 28 wind power facilities.

The PJM Market Implementation Committee endorsed the creation of a fifth cost of new entry area for the Commonwealth Edison zone, as well as two proposals aiming to limit the prospective performance impact of implementing multi-schedule modeling in the market clearing engine.

MISO said it will push back a contentious filing for a new, marginal approach to capacity accreditation into early next year.

Market Monitors Joe Bowring and David Patton have doubts about the wisdom of large-scale transmission expansions, warning they may crowd out market solutions.

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.

FERC reaffirmed its support for NYISO’s 17-year amortization period in its installed capacity market, rejecting protests from state regulators and consumers.  

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.
