“Solar-charged batteries” can help solve California’s energy shortage, with energy storage already playing a small but active role in mitigating the struggle to meet peak energy demand, according to the leadership of two trade associations based in the US state.

The UKs largest council-owned battery storage site, the 30MW Fideoak Mill site, is now fully operational and able to participate in delivering multiple revenue-generating services.

Peer-to-peer (P2P) energy trading using distributed battery storage in Japanese households could be a scalable business once prohibitive rules change in a couple of years’ time, a provider of renewable energy equipment in the country has said.

AES Corporation reaffirmed its 2020 financial guidance in presenting its latest quarterly results, which showed a total backlog of renewables and energy storage contracts of 6.2GW, while the company said it will reduce generation from coal to less than 30% of its total capacity by the end of this year.

California investor-owned utility (IOU) Pacific Gas & Electric has begun work constructing a 182.5MW / 730MWh battery energy storage system (BESS) project at a substation in California.

Long duration energy storage is “essential” to help accelerate renewable deployment, according to the US Department of Energy’s Dr Imre Gyuk, who moderates this panel discussion with Matt Harper from flow battery provider Invinity Energy Systems and Russ Weed from gravity energy storage company ARES.

The 20MW / 80MWh Pomona battery energy storage facility, in operation in California since a fast-track process brought it online in partial response to the 2015 Aliso Canyon gas leak, has been bought by Ormat Technologies.

Tesla CEO Elon Musk and fellow executives talked up the potential for Tesla Energy to reach “roughly the same size” as the company’s automotive business in an earnings call with analysts held yesterday.

Transmission and distribution network operator Hokkaido Electric Power has contracted Sumitomo Electric Industries to supply a grid-scale flow battery energy storage system for a wind farm in northern Japan.

While lithium-ion batteries continue to take the dominant share of new installations by some distance, there are a variety of other technologies looking to complement, combine or even compete. Panellists at the Energy Storage Digital Series looked at the questions of which energy storage technologies are the likeliest contenders for that future.
