Talen Energy, a US independent power producer (IPP) with a 13GW portfolio of generation assets, has contracted energy storage developer Key Capture Energy to install a battery storage system at the site of a coal power plant in Maryland.

Google is investing in battery energy storage to serve as a backup power solution at one of its data centres, in a project described as a first step in changing data centres “from climate change problems to critical components in carbon-free systems”.
