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.

Uncertainty persists around the impact bankruptcy proceedings brought about at investor-owned utility Pacific Gas & Electric (PG&E) could have on renewables contracts and energy storage projects as it faces “extensive litigation” and “significant liabilities” for California wildfires.

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.

While research published this week demonstrates that the US as a whole is embracing energy storage technology, with regulator FERC’s recent wholesale market ruling likely to have a “significant impact”, the picture varies greatly when looking from state-to-state, an analyst has said.

The “devil is in the detail” when it comes to making regulatory changes in the US to open up wholesale markets for energy storage to participate in, a regional chief of regulator FERC has said.

Regulators, policymakers, experts, developers, utilities, aggregators and of course, energy storage industry participants will fill out the Victoria Park Plaza in London next week to discuss everything impacting the deployment of energy storage.

A unanimous vote taken by the US regulator FERC (Federal Energy Regulatory Commission) which would allow energy storage and other distributed energy resources to play into wholesale markets has been hailed as a “significant step” forward.

We often hear about California’s leading position in solar and latterly in energy storage. Perhaps lesser known than direct policy support for energy storage and renewable technologies is the way California’s network operator (CAISO) is starting to reconfigure how it procures demand response, with a positive impact for energy storage – and particularly behind-the-meter assets, as Ted Ko, policy director of Stem, explains.

Energy storage companies “have suffered significant and detrimental harm” from changes to rules governing the frequency regulation market in US regional transmission organisation (RTO) PJM Interconnection’s service area, the Energy Storage Association has said.
