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.

According to the latest GTM Research figures, energy storage is coming into its own and is no longer confined to a handful of US states. 21 states now have 20MW of storage projects proposed, in construction or deployed. Further, 10 states have pipelines of more than 100MW.

An energy trade association which includes Apple, energy storage maker AES and solar giants SunPower and First Solar in its leadership has welcomed the proposal by US energy regulator, FERC, to remove barriers to participation in wholesale markets for energy storage and distributed energy resources (DERs).

There is a significant opportunity for energy storage under the Trump administration, the US Energy Storage Association has said.

Energy storage should be properly valued and supported at federal level in the United States, according to a government document analysing and evaluating energy policy released by officials of the outgoing Obama administration.

US energy storage had a fairly quiet period in the third quarter of this year deploying just 16.4MW/31.4MWh but enjoyed a record quarterly sum of US$660 million of corporate investment.

The US energy regulator has opened a consultation process on the integration of energy storage into a competitive market structure.

Energy storage in the US is being propelled forward by falling costs and increasingly favourable markets and policy. But for the full value of storage to be realised, numerous regulatory and fiscal barriers must still be surmounted, writes Matt Roberts.

Operators of transmission infrastructure and wholesale markets in the US have supplied their views on energy storage to the Federal Energy Regulatory Commission (FERC), with industry and other stakeholders expected to follow. Energy-Storage.News’ Andy Colthorpe spoke with Energy Storage Association policy expert Jason Burwen on what he describes as a “systematic review” that could have a transformative effect on the market and drivers for storage.
