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.

San Diego Gas & Electric (SDG&E), one of California’s three main investor-owned utilities (IOUs), said this week that it will add resilience and backup capabilities to public sector buildings through the procurement of “up to 166MW” of energy storage.

Kicking off with an unprecedented wave of policy commitments, 2018 promises to be an exciting year for energy storage in New York State. William Acker at NY-BEST explains what’s going on – and what should happen next.

AES Distributed Energy (AES DE), a subsidiary of AES Corporation, and nonprofit transmission firm Kauai Island Utility Cooperative (KIUC) have broken ground on a 28MW solar and 100MWh five-hour duration battery energy storage system in Kauai, Hawaii.

In a feature article from the latest volume of PV Tech Power, the editorial team at Energy-Storage.News canvassed the opinions of trade association chiefs from five key global regions. Here’s some ‘bonus’ content…

Microgrids ensure energy security for mission-critical loads at military bases, and reduce reliance on fuel during grid outages. While they have much in common with many of the technologies used in ‘other’ microgrids, the stringent technical requirements involved add a new layer of complexity, explain Lisa Laughner and Tony Soverns from provider Go Electric.

The addition of energy storage has made a 1MW community rooftop solar project in Massachusetts viable, after a long-term PPA was secured with a local utility.

The US’ two leading states in solar and energy storage, New York and California, have taken steps towards valuing the locational and time-of-use value of distributed energy resources and other states should follow, the Solar Energy Industries Association (SEIA) has said.
