The US deployed 42% megawatts more energy storage in the second quarter of this year than in the first, with residential installations overtaking utility deployments for the first time.

US utilities deployed more than 520MWh of energy storage on their networks in 2017, bringing the country’s cumulative installed capacity of grid-connected energy storage systems to over 1GWh, trade organisation Smart Electric Power Alliance (SEPA) has found.

A household just outside Berlin has become the recipient of the 100,000th grid-connected residential battery energy storage system in Germany.

In the second part of our interview with Valts Grintals, analyst at Delta-ee we discuss why behind-the-meter energy storage, including commercial and industrial (C&I) and residential installations, contributed so much to the market’s recent success.

Europe’s installed base of electrical energy storage leaped by almost 50% during 2017 but perhaps the bigger takeaway is the growing share of battery systems installed behind-the-meter, an analyst has said.

Energy storage in the US has just enjoyed its greatest quarter for megawatt-hours deployed, up almost 1000% from the equivalent period last year, installing 233.7MWh.
