EDF Power Solutions North America and Masdar Sign 15-Year Power Purchase Agreements For BigBeau Solar+Storage Project In California

EDF power solutions North America and Abu Dhabi Future Energy Company – Masdar, who jointly own the BigBeau Solar+Storage Project, have recently entered into long-term agreements that further strengthen their role in supporting California’s growing clean energy demand. The two companies have signed 15-year power purchase agreements covering the full output of the 128 MWac solar facility along with its 40 MW/160 MWh battery energy storage system.

These agreements mark an important step in ensuring long-term energy delivery stability while supporting the state’s transition toward a cleaner and more resilient power system.The BigBeau project is located in Kern County, California, a region that has become a key hub for large-scale renewable energy development due to its strong solar resources and expanding transmission infrastructure.

The project has been operational since December 2022 and has already been supplying electricity to the grid. Under the new agreements, it began delivering power to Southern California Edison (SCE) from February 1, 2026, reinforcing its role in meeting utility-scale electricity demand across Southern California. The combination of solar generation and battery storage makes the BigBeau facility particularly important for grid reliability.

While the 128 MWac solar plant produces renewable electricity during daylight hours, the 40 MW/160 MWh battery storage system allows excess energy to be stored and dispatched when demand is higher or when solar generation is not available. This integration helps smooth out variability in renewable generation and supports a more stable and flexible electricity supply for the grid.

As California continues to experience rising electricity demand driven by population growth, electrification, and increased use of digital infrastructure, such hybrid renewable projects are becoming increasingly valuable. Representatives from both companies highlighted the importance of the agreement in strengthening their long-term partnership with Southern California Edison and supporting the utility’s clean energy goals.

According to Masdar, the agreement reflects its growing portfolio in the United States and its broader strategy of scaling utility-scale clean energy projects that can reliably meet increasing demand. The company emphasized its focus on investing in large renewable energy assets that contribute to energy security, sustainability, and long-term system resilience. EDF power solutions North America also reaffirmed its commitment to supporting decarbonisation efforts through integrated energy solutions.

With decades of experience in renewable energy development, the company has built a substantial portfolio of wind, solar, and storage projects across North America. Its involvement in the BigBeau project reflects its broader approach to combining generation and storage technologies in order to deliver more reliable clean energy solutions to utility customers. The company also highlighted its ongoing partnership with Southern California Edison and expressed interest in expanding similar collaborations in the future.

The BigBeau Solar+Storage Project is part of a wider partnership between EDF power solutions and Masdar, under which the two companies have agreed to jointly develop seven projects with a combined capacity of approximately 1.1 gigawatts. This partnership reflects a shared strategy of expanding large-scale renewable energy infrastructure to support the increasing demand for clean electricity across the United States.

Masdar has been active in the United States since 2019 and has steadily increased its investments in the American renewable energy sector. The company has committed several billion dollars to date and is working toward developing a portfolio of up to 25 gigawatts within the next decade. Its long-term strategy focuses on delivering clean energy solutions that enhance energy resilience, support decarbonisation goals, and contribute to the broader expansion of renewable energy capacity in key global markets.

As electricity demand continues to grow in California and across the United States, projects like BigBeau demonstrate how solar-plus-storage systems can play a critical role in meeting future energy needs. By combining renewable generation with flexible storage capabilities and long-term supply agreements, such projects help ensure that clean energy can be delivered reliably and efficiently to utilities and end users.
