Still hoping to win approval for its proposed revamp of capacity market rules, PJM asked the Federal Energy Regulatory Commission Tuesday to delay the May 11-15 Base Residual Auction.

On March 31, FERC said PJM’s Capacity Performance proposal was deficient and gave the RTO 30 days to provide additional information (ER15-623). (See FERC: PJM Capacity Performance Filing ‘Deficient.’)

PJM’s filing Tuesday asked for permission to delay the BRA until 30 to 75 days after a commission order on the merits of the proposal, but no later than the week of Aug. 10-14 (ER15-1470).

The RTO requested that the commission act on its request by April 24, with comments due by April 14.

Andy Ott, executive vice president for markets, will brief the Market Implementation Committee at about 10:30 a.m. Wednesday on the RTO’s plans for responding to the deficiency order.
