FERC had said neither ISO-NE’s nor the New England Power Pool’s proposals in themselves addressed performance adequacy, but the commission adopted elements of both.

New England politicians' urge to “do something” to combat high winter power prices risks undermining ISO-NE’s power market just as it has begun adding new generation, the head of NEPGA said.

NEPOOL joined ISO-NE in asking FERC to reject a request by generators to force the RTO to develop a zonal sloped demand curve design for FCA 10 in February.

NEPGA says ISO-NE should adhere to a planned change to a sloped demand curve in the next Forward Capacity Auction.

FERC backtracked from its January order directing ISO-NE to develop a market-based approach for its winter reliability program later this year.

ISO-NE must find a market-based solution for ensuring adequate generation by next winter, the FERC said last week in a clarification of a previous order.

FERC approved rule changes allowing ISO-NE grid operators to fully integrate demand response into their wholesale markets.

ISO-NE generators, including NEPGA, asked FERC to change the New Entry Pricing Rule and the Peak Energy Rent Adjustment ahead of February’s FCA 9.

U.S. Solicitor General Donald Verrilli said he will ask the Supreme Court to review an appellate court ruling voiding the FERC’s authority over DR in wholesale energy markets.
