One of Sweden’s DNOs Ellevio Group is investing in four new battery storage projects totalling 70MW, supplied by Alfen, the latest in a series of large-scale projects.

A 30MW battery energy storage system has been inaugurated by transmission system operator (TSO) ISA CTEEP in Brazil.

The German battery storage market continues to be dominated by the residential segment which accounted for 93% of the 1,350MWh of capacity installed last year, according to research by a group of Aachen-based institutions.
