Long Duration Energy Storage Program | California Energy Commission Long Duration Energy Storage Program The Long Duration Energy Storage (LDES) program invests in projects that accelerate the implementation of long duration energy storage solutions to increase the resiliency and reliability of our energy infrastructure and meet the state's energy and climate goals.
The Long Duration Energy Storage (LDES) program has been allocated over $247 million to invest in the demonstration and deployment of non-lithium-ion long duration energy storage technologies across California, paving the way for opportunities to foster a diverse portfolio of energy storage technologies that will contribute to a safe and reliable future grid.
The LDES program, in part, leverages funding made available through the California Climate Investments initiative, and is aligned with its goals of prioritizing disadvantaged communities and providing energy savings, direct economic benefits, emission reductions, and supporting grid resiliency. LDES technologies play an important role in achieving California's zero carbon goals.
As the deployment of intermittent renewable energy sources accelerates and the frequency of extreme weather events increases due to climate change, there is a growing need for storage technologies with extended energy-duration capabilities to maintain grid reliability. The LDES program prioritizes projects that will benefit Justice Communities and maintains a strong focus on projects that benefit Native American tribes in California.
Valley Children’s Hospital In 2025, the CEC awarded Charge Bliss, Inc. a $28 million grant award to deploy an LDES system to support a microgrid serving the Valley Children’s Hospital in Madera, CA. The project will provide energy resiliency in a region that is increasingly at-risk for significant and prolonged power outages.
Additionally, it will provide a roadmap for deploying clean backup power systems at acute care facilities, and demonstrate the performance, safety, and reliability of LDES as a viable alternative to fossil fuel-based resources. The system is expected to be commissioned in 2029.
In 2025, the CEC awarded Pacific Steel Group a $14 million grant to deploy a 4 MW/32 MWh zinc hybrid cathode battery LDES system to support the Mojave Micro Mill project in Mojave, California. The first-of-a-kind Mojave Micro Mill innovative clean energy project will support a $630 million zero carbon emission electrified rebar steel mill plant.
The LDES system will be integrated with the plant’s on-site microgrid and solar PV system to provide clean electricity, reliable backup power, optimize renewable energy use, and support the energy-intensive, rapidly fluctuating demands typical of steel mill operations. The system is expected to be commissioned in 2027. In 2024, the CEC awarded Eos Energy Storage, LLC.
an $8 million grant to deploy a 1 MW/8 MWh zinc hybrid cathode battery LDES system at Naval Base San Diego as part of a microgrid project. The Navy has committed $3. 9 million in funding toward constructing the microgrid with 300 kW of solar PV to support its critical facilities.
The LDES system will help meet the Base’s 14-day backup power requirement for critical operations while enhancing the reliability and resilience of its energy infrastructure. The system is expected to be commissioned in 2027. Marine Corps Base Camp Pendleton, San Diego County In 2024, the CEC awarded International Electric Power, LLC.
a $42 million grant to deploy and operate a 48 MWh zinc hybrid cathode LDES system at the Haybarn Energy Resiliency Center at Marine Corps Base Camp Pendleton. The LDES system will be operated as a part of a microgrid that will power the Base’s critical operations during outages and periods of peak demand.
The LDES system will participate in energy markets during normal grid operations and provide backup power to the Base during outages, demonstrating LDES technology’s ability to deliver wholesale market revenue while providing reliability and resiliency. Successful deployment of this system may lead to expansion of the LDES system onsite to a size of 50 MW/400 MWh. The system is expected to be commissioned in 2027.
Rapid Integration and Commercialization Unit In 2020, the CEC awarded a $5 million Electric Program Investment Charge (EPIC) program grant award to Indian Energy to demonstrate the utility of deploying multiple LDES systems to maximize a microgrid system’s load and response capabilities. The resulting Rapid Integration and Commercialization Unit (RICU) is located aboard the Marine Corps Air Station Miramar (MCAS Miramar) in San Diego.
The RICU consists of a microgrid system connected to a solar array with multiple points for energy storage installations. Following the success of the RICU EPIC project, the CEC awarded an additional $4. 85 million grant for the RICU in June 2024 to execute a second phase of demonstration and research.
The RICU has been recognized as a valuable testing facility capable of evaluating the performance and safety of energy storage technologies and aiding in the establishment of safety guidelines addressing potential safety incidents involving LDES technologies for emergency first responders.
The insights gained from the RICU project have the potential to play a key role in California’s energy future by facilitating the large-scale adoption of LDES for grid reliability and renewable energy integration. Paskenta Band of Nomlaki Indians In 2023, the CEC awarded Charge Bliss Inc. a $32.
7 million grant to demonstrate a 5 MW solar photovoltaic and 15 MWh LDES system to support the Paskenta Band of the Nomlaki Indians located in Corning, California. The project will deploy non-lithium-ion battery technology capable of supplying power for approximately 18 hours. The system will consist of a microgrid that will support local grid resiliency and meet the tribe’s energy needs, ultimately enhancing their energy sovereignty.
The system is scheduled to be operational by 2027. In 2023, the CEC awarded Form Energy Inc. a $30 million grant to install a 5 MW/500 MWh iron-air energy storage system on Pacific Gas & Electric Company’s (PG&E) substation at Redwood Valley, Mendocino County, California. In 2025, the energy storage system capacity was changed to 1.
5MW/150 MWh to accommodate charging restrictions at PG&E’s Mendocino substation, with CEC funding reduced to $25 million and Form’s match funding increased to $25 million. Form Energy’s storage system supports grid reliability and resilience by supplying up to an unprecedented 100 hours of continuous power during extreme weather conditions and grid outages. The system is expected to be commissioned in 2027.
Viejas Band of Kumeyaay Indians In 2022, the CEC awarded Indian Energy, a privately held Native American-owned microgrid developer, a $31 million grant to install a 60 MWh LDES system on Viejas Tribe of Kumeyaay Indians land in San Diego County. In 2024, the scope of the agreement was expanded by increasing the project budget $12 million and deploying an additional 10 MWh of batteries, resulting in a total system size of 70 MWh.
The vanadium flow and zinc hybrid cathode battery technologies deployed at this site are capable of providing up to 10 hours of power, providing renewable backup power to the Viejas community in the event of electricity outages and enhancing the tribe’s energy sovereignty. The full system—including the 70 MWh of storage and 15W of solar—is expected to be operational in 2026.
