Hawaii’s electricity regulator and main utility have recognised that customer-sited distributed energy resources (DERs), including rooftop PV and energy storage, can provide essential grid services and better visbility for network operators, the VP of Stem Inc’s Hawaii operations has told Energy Storage News.

The organisation responsible for overseeing California’s bulk electric power system has approved proposals to accommodate more distributed energy resources, including rooftop solar, energy storage, advanced inverters and demand response, onto the state’s grid.

A US company which analyses Big Data for energy applications has claimed a world first with its involvement in a Dutch project to integrate multiple distributed energy resources into a single system.

Production of stationary storage systems has already begun at Tesla’s facilities in Fremont California, while the company’s Gigafactory is “on track” and could even be expanded beyond original plans, company executives said yesterday.
