Revisions aimed at enabling energy storage’s participation in wholesale markets, proposed by New England’s Independent System Operator (ISO) have been accepted by the Federal Energy Regulatory Commission (FERC), effective 1 April this year.

Solar-plus-storage systems in ordinary households will provide 20MW of energy capacity in New England, with Sunrun announcing the award of a contract from the state’s ISO (independent system operator).

Transmission system operators in the US have begun making their moves to accommodate energy storage into their wholesale markets, with New England ISO and Southwest Power Pool both making filings in the past month.
