The NYISO Management Committee discussed the latest Reliability Needs Assessment and a heat wave that prompted a mandatory systemwide demand response event.

FERC approved the CAISO plan to for a new market mechanism for itself and the Western EIM designed to integration of variable renewable energy resources.

FERC said it is considering changing how it evaluates market power in electric utility mergers and applications for market-based rate authority.

FERC is considering changes to its Electric Quarterly Report rules, including requiring data on ancillary services transactions and changes to how financially settled trades are reported.
