California Energy Storage Showcase
LITHIUM-ION BATTERY SUPPORTS RENEWABLE ENERGY INTEGRATION

Using energy storage to reduce the costs of serving peak electricity demand

Sacramento Municipal Utility District (SMUD) is demonstrating a 500kW/125Wh advanced lithium-ion battery energy storage system developed by Mitsubishi Heavy Industries to evaluate the technology’s ability to support the integration of a solar photovoltaic system into the power grid. The battery will be tested for its ability to provide solar photovoltaic firming, peak electricity demand shaving, ramp rate control, and simulated frequency regulation support. If successful, SMUD will use this demonstration project as a basis for using similar battery energy storage technologies to reduce the costs of serving peak electricity demand and the integration of more renewable energy.
