Green Mountain Power, a utility company in Vermont, has begun using Tesla Powerwall energy storage systems in customers’ homes as a frequency regulation resource to benefit the regional grid.

Approval has been granted — with significant conditions attached — for a large-scale standalone battery storage project designed to help the Hawaiian island of Oahu overcome energy reliability and supply concerns as a coal power plant retires.

Foresight Solar Fund, a UK-based investment company with over a gigawatt of solar PV assets in its portfolio, has made its first move into the battery storage space.

With batteries today finally reaching the size and capacity that enables renewables to replace medium-sized natural gas generators, a future ruled by solar and storage is just around the corner, writes Radoslav Stompf, CEO of FUERGY.

ENGIE has sold its 60.5% stake in stationary storage and e-mobility solutions company ENGIE EPS to Taiwan Cement Corporation (TCC).

Battery storage can be a significantly cheaper and more effective technology than natural gas in providing peaking capacity, according to a new study released by the Clean Energy Council, the industry group which represents Australia’s clean energy sector.

A 100MW battery energy storage system just announced in the UK by battery storage developer, owner and operator Zenobe Energy is the first such system to win a long-term contract from the country’s transmission system operator to directly absorb reactive power from the transmission network.

Software is rapidly becoming recognised as key to the value proposition and bankability of energy storage, which in turn lies at the heart of the energy transition. Andy Colthorpe speaks to three providers of software aimed at the energy storage industry.

While interconnection queues for America’s electric transmission and distribution operators are “swelling up” with growing numbers of energy storage projects, some of the big challenges ahead include enabling fair market participation for both standalone storage and storage paired with generation.

A lithium-ion battery energy storage system that has been switched on in Rani Bagh, Delhi, will serve multiple applications and could pave the way for adoption of smarter energy networks based on renewable energy across India.
