The NYPSC had argued that it had sole jurisdiction over the rates and terms of an RSSA it had ordered between Exelon’s troubled R.E. Ginna nuclear plant and Rochester Gas & Electric.

Efforts to keep the Ginna nuclear plant operating has spurred a turf war between federal and state regulators who are conducting independent reviews.

The NYPSC says the FERC’s recent order on reliability-must-run agreements “interferes” with state authority as it tries to address generation shortages in the state.

FERC last week ordered hearing and settlement procedures in a dispute over the costs of keeping NRG’s Dunkirk generating plant online for reliability.

NYISO must amend its Tariff to establish uniform rules for identifying and compensating reliability-must-run (RMR) generators, FERC ruled Thursday.

PJM says critics of its requests to safeguard capacity for the 2015/16 delivery year ignored the context of its filings with FERC.

PJM wants a one-time waiver to avoid releasing 2,000 MW of capacity for the 2015/16 delivery year, when the RTO fears it may run short of resources due to retirements of coal-fired generation.

PJM officials are seeking to postpone generation retirements — or accelerate planned new generation — to help the RTO ride through potential shortages next winter.
