Sturgeon Electric Completes Arizona’s Largest Battery Storage Facility

MYR Group Inc., through its subsidiary Sturgeon Electric, has successfully completed the Sierra Estrella battery energy storage system $(BESS)$ project in Avondale, Arizona. The 250MW/1,000MWh facility, featuring 276 BESS units, is now the largest standalone battery storage installation in the state. Despite supply chain challenges and changes in suppliers, Sturgeon Electric completed the bulk of the electrical construction, including a new 230kV/34.5kV substation, in less than five months and achieved substantial completion nearly a month ahead of schedule. The project was delivered under budget with additional scope enhancements, and the system went online in April 2024.
