Europe-based organic flow battery company CMBlu has won its second US project, a 5MW, 10-hour duration pilot system with Arizona utility Salt River Project (SRP).

A 250MW/1,000MWh battery energy storage system (BESS) project in Arizona will soon break ground, utility SRP and developer Plus Power said.

Arizona utility Salt River Project (SRP) has followed up the recent completion of a 10MW battery storage system at a solar farm by beginning work on its first standalone grid-scale battery energy storage project.
