SMA Solar Technology AG—Press Release SMA Battery Inverter Sunny Central Storage Secures Grid Stability in California Niestetal/ Rocklin, November 15, 2017— SMA Solar Technology AG (SMA) is delivering 13 Sunny Central Storage battery inverters for the Los Angeles Department of Water and Power’s (LADWP) Beacon Energy Storage System, providing comprehensive grid management services and thus ensuring grid stability. The 20 megawatt battery storage project, located in the Mojave Desert in California, integrates solar power into the grid and will help LADWP to meet its target of 178 MW of new energy storage by 2021. The storage project mitigates the volatile energy production of 600 MW of solar power and 135 MW of wind power generated by several utility-scale renewable energy projects in neighboring Kern County. SMA’s Sunny Central Storage 2750-EV-US battery inverter, which is compatible with different types of battery technology, will provide comprehensive grid management services to allow the integration of renewable energy into the grid while ensuring maximum grid stability. “We’re so happy this project could be realized with Sunny Central Storage battery inverters,” said Volker Wachenfeld, Executive Vice President Business Unit Offgrid and Storage at SMA. “Global demand for storage technologies is rising and the seamless integration of renewable energies will become one of the major challenges for the energy supply of the future.
