CSU Long Beach Pumped Hydro Storage Facility, Long Beach, California

CSU Long Beach is a pumped hydro storage facility located in Long Beach, California, United States. With a capacity of 2.5 MW, it is a small-scale energy storage plant that plays a role in local grid management and renewable energy support. The facility is owned by Advanced Microgrid Solutions and is currently operational. The plant utilizes pumped hydro storage technology, which stores energy by pumping water to an elevated reservoir and releasing it through turbines to generate electricity when needed. The 2.5 MW capacity indicates a focus on short-duration grid services like frequency regulation or peak shaving. In the United States, pumped hydro storage facilities are subject to safety and performance standards, including NFPA 855 for energy storage systems and UL 9540 for safety. Located in the Los Angeles metropolitan area, the facility contributes to the region's energy resilience and supports the integration of variable renewable sources like solar and wind. Its proximity to urban infrastructure underscores the importance of siting and safety considerations, including thermal runaway risk management and adherence to local fire codes. The plant's role in the microgrid context highlights its value for campus or community energy independence.

Pumped hydro storage facilities like CSU Long Beach operate with low direct emissions but require careful siting due to water usage and ecological impacts. In urban areas, safety concerns include potential flooding from reservoir failure and noise during operation. The facility's location near populated areas necessitates compliance with fire codes and risk mitigation for thermal runaway, though pumped hydro is inherently less prone to such risks compared to lithium-ion batteries. Grid interconnection allows for peak shaving and frequency response, reducing reliance on fossil fuel peaker plants.
