Millikan BESS - 2 MW Battery Energy Storage in Irvine, California

Millikan BESS is a battery energy storage facility located in Irvine, California, United States. With a capacity of 2 MW, it is a small-scale system designed to provide grid services such as peak shaving and frequency regulation. The facility is owned and operated by esVolta LP, a developer of energy storage projects across North America. The facility operates under the regulatory framework of the United States, which includes safety standards such as NFPA 855 for energy storage systems and UL 9540/9540A for battery safety testing. California's aggressive renewable energy targets and grid modernization efforts create a favorable environment for battery storage, with the state leading in installed capacity. The 2 MW scale is typical for behind-the-meter or community-level storage projects. Millikan BESS contributes to local grid resilience by storing excess renewable energy during low-demand periods and discharging during peak hours. This helps reduce reliance on fossil fuel peaker plants and supports California's goal of 100% clean electricity by 2045. The facility's location in a densely populated area underscores the importance of robust safety protocols to mitigate thermal runaway risks associated with lithium-ion batteries.

The facility is situated in Irvine, California, a region with a Mediterranean climate and high solar energy potential. Battery storage systems like Millikan BESS play a critical role in managing the intermittency of solar power, reducing curtailment, and displacing natural gas peaker plants. However, the use of lithium-ion chemistry introduces thermal runaway risks, which are mitigated by adherence to NFPA 855 and UL 9540 standards. Siting near residential areas requires careful planning for fire safety and noise management.
