Distributed energy resources (DERs) will be able to participate in US wholesale energy markets following a “landmark” new ruling from the Federal Energy Regulatory Commission (FERC).

Approval has been given to the compliance plans of two more US RTOs and ISOs to be filed under FERC Order 841, the ruling set by the US Federal Energy Regulatory Commission (FERC) designed to open up regional grid operators’ wholesale markets to electricity storage.

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.

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.
