First Solar and Arevon have teamed up to develop the largest solar-plus-storage project in the United States, featuring a capacity of 758MW of solar energy generation. The project is located at the Eland solar facility in California, with construction already underway as of March 18, 2025.
This initiative is poised to become the largest solar and storage project in the United States, integrating Megapack storage systems with a total capacity of 300MW / 1.2GWh to support the 758MW solar project. Currently, the project has already installed 172 Megapack units and 136,000 solar panels. According to the developers, these solar panels will meet the annual energy needs of approximately 20,000 households.
Furthermore, First Solar has indicated that the project will enhance grid stability through the deployment of power control systems, ensuring a stable output of electricity to the grid. The goal is to achieve 100% renewable energy supply by 2035.
As per the information provided, the energy storage component is expected to be operational by December 2024, with an initial capacity of 150MW / 600MWh. The project will later expand its storage capacity to 300MW / 1.2GWh, with a total investment projected to exceed $20 billion.
In summary, the collaboration between First Solar and Arevon marks a significant step towards large-scale renewable energy solutions in the United States, contributing to the country’s transition to sustainable energy.
