PJM on Friday filed its long-awaited Capacity Performance proposal with the Federal Energy Regulatory Commission, a two-docket, 1,275-page capacity market overhaul that it hopes will prevent a repeat of last January’s poor generator performance.

EL15-29, filed under sections 205 and 206 of the Federal Power Act, contains proposed changes to PJM’s Operating Agreement and Tariff “to correct present deficiencies in those agreements on matters of resource performance, and excuses for resource performance, in the wholesale markets administered by PJM.”

ER15-623, filed under section 205, proposes changes to the Reliability Pricing Model rules in the Tariff and Reliability Assurance Agreement.

PJM asked FERC to allow an extended, one-month comment period ending Jan. 12. PJM requested that the changes go into effect on April 1, 2015. (See What You Need to Know about PJM’s Capacity Performance Proposal.)
