US outgoing President Joe Biden has signed a bi-partisan bill into law allowing Arizona utility Salt River Project (SRP) to move forward with a pumped hydro energy storage project.

Canadian-headquartered developer-operator Aypa Power announced successful close of a US$398 million financing package for the 250MW/1,000MWh Pediment BESS project.

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.

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.
