Overview
The Mira Loma Energy Storage Facility is a 20 MW pumped hydro storage plant in California, owned by Southern California Edison Co. It supports grid stability and peak shaving in the region.
The Mira Loma Energy Storage Facility is a pumped hydro storage plant located in California, United States. Owned by Southern California Edison Co, the facility has a capacity of 20 MW, positioning it as a small-to-medium scale energy storage asset within the state's diverse energy portfolio. The plant is operational and plays a role in the local grid infrastructure. As a pumped hydro storage facility, it utilizes two water reservoirs at different elevations to store and generate electricity. The 20 MW capacity allows for rapid response to grid demands, providing services such as peak shaving and frequency regulation. In the context of California's ambitious renewable energy targets, such storage facilities are critical for integrating variable solar and wind power. Environmentally, pumped hydro storage has a relatively low operational footprint but requires significant land and water resources. The facility's location in California subjects it to state regulations on water use and environmental impact. It contributes to reducing reliance on fossil fuel peaker plants, thereby supporting the state's greenhouse gas reduction goals.
Environmental context
Pumped hydro storage facilities like Mira Loma rely on water reservoirs, which can affect local aquatic ecosystems and water availability. In California, drought conditions and water rights are key environmental considerations. The facility's operation must comply with state environmental regulations, including those governing water use and habitat protection. Additionally, the plant's role in grid stabilization helps reduce emissions by enabling higher penetration of renewable energy sources.
