The Battle Mountain Solar field was an Engineer Procure Construct (EPC) delivery project, providing power to Sierra Pacific Power under contract for the next 25 years. The project is a 132-MWdc photovoltaic (PV) plant, which features 100MWh/25MWdc of battery energy storage for a four-hour period. The facility’s 25 megawatts of battery capacity makes it among the nation’s largest DC-coupled combined solar and battery storage systems. As part of NV Energy’s Integrated Resource Plan, Battle Mountain will bring 1,001 MW of new renewable energy projects to Nevada.
Completed with the new substation to connect to the Sierra Pacific Power grid, the project covered 700 acres with 39 divisions. Summit provided inspection and material testing for the project which included the construction of the substation pad and foundations for the poles, and utility structures. The project had one 14-acre substation, roughly 60,000 LF of electrical service trenching, 39 battery storage structures, and 15,000 LF of access road. Summit also performed water quality testing for water used on-site for dust control and operations. The site utilized the native soil as bedding by recycling the excavated material and screening it in place for large particles.
