**MYR Group Inc. Completes Arizona's Largest Standalone Battery Storage Facility** MYR Group Inc., through its subsidiary Sturgeon Electric, has successfully completed the Sierra Estrella Battery Energy Storage and Substation project in Arizona. The facility, the largest standalone battery storage installation in the state, boasts a capacity of 250MW/1,000MWh, with 276 battery energy storage units capable of powering more than 50,000 homes for up to four hours. Sturgeon Electric handled all electrical construction and material procurement for both the BESS facility and its associated 230kV/34.5kV substation. Despite a compressed schedule and several unforeseen challenges, including supply chain disruptions and extreme summer heat, the project was completed nearly a month ahead of schedule. The project supports Arizona utilities' transition to cleaner, more reliable energy.
