Iowa’s energy regulator has approved two projects from NextEra Energy Resources including a 300MWh co-located battery energy storage system (BESS) while utility Alliant has turned on a 5MW unit in the state.
Developer Black Mountain Energy Storage (BMES) has sold 700MW of development-stage projects to UBS Asset Management, its third substantial sale in the Texas, ERCOT market in two months.
Some 5GWh of utility-scale battery energy storage was deployed in the first half of 2022, up one third while wind and solar fell 50-70%, according to American Clean Power (ACP).
