PJM staff outlined recommendations it developed to address a mysterious frequency drop on July 10.

FERC clarified that Order 842 did not imply that existing generators are entitled to compensation for providing primary frequency response.

Calpine and AEP are offering alternatives to plans for complying with FERC Order 842, which requires some generators to provide primary frequency response.

Although FERC has required almost all new generating units to provide primary frequency response (PFR), PJM stakeholders are strongly opposing any move by the RTO to require existing units to follow suit.

PJM debated stakeholders over whether existing units should be under the same obligation to provide primary frequency response that FERC ordered for new units.

PJM will hold its spring restoration drill May 15-16, staff told attendees at last week’s Operating Committee meeting.

New generators seeking interconnections must be equipped to provide primary frequency response, FERC ruled.
