Arizona utility Salt River Project (SRP) and renewables developer NextEra Energy Resources have commissioned a 1GWh battery energy storage system (BESS) in Buckeye, Arizona, US.

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).

Power company AES Corporation is investigating the cause of what has been described as a thermal runaway incident at a 10MW battery energy storage system (BESS) site it owns and operates in Chandler, Arizona.

Salt River Project is to build the largest solar-plus-storage project in Arizona, just as an historic coal plant is put to rest.

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.

NextEra Energy Resources will build a 10MW lithium-ion battery storage system paired with a 20MW PV installation for Arizona utility Salt River Project, with another battery system on the way.
