The U.S. Now Has The World’s Largest Solar And Battery Energy Storage Project

The Edwards Sanborn Solar and Energy Storage project, spreading across 4,600 acres in California, represents a great monumental and revolutionary leap in renewable energy infrastructure. With its remarkable capacity to generate a whopping of 875 megawatts of solar power and store 3.3 gigawatt-hours of energy, it significantly contributes to the reduction of carbon emissions. This amounts to 320,000 tons annually and can supply and run power to approximately 238,000 homes.

All this has been made possible by the deployment of 1.9 million solar panels and 120,720 batteries sourced from companies like First Solar, LG Chem, Samsung, and BYD. The project’s scale is further highlighted by the extensive wiring, totaling 98 miles of medium voltage and 361 miles of direct current wiring.

Situated partly on the Edwards Air Force Base, the project is emblematic of large-scale solar initiatives in the United States and stands as the largest public-private partnership in the history of the US Department of Defense. The construction which is led by Mortenson, has involved over 1,000 workers and culminated in over a million hours of injury-free labor. The project commenced in early 2021, reached its operational status by February 2023 and achieved its full capacity in January 2024.

Notably, the Edwards Sanborn project eclipses its predecessors, including the Vistra Moss Landing project, to become the largest energy storage site in the US and globally. It also competes with colossal solar farms worldwide, such as China’s Golmud Solar Park and India’s Bhadla Solar Park.

While hailed as a cornerstone in the transition to renewable energy, solar power confronts challenges. Its intermittency necessitates robust storage solutions, predominantly reliant on batteries containing rare metals like lithium and cobalt, sourced from environmentally taxing mining processes. Moreover, the expansive land requirements for solar infrastructure, exemplified by the transformation of California’s Mojave Desert, encroach upon sacred territories of Native American tribes and endanger local wildlife.

Despite these challenges, the Edwards Sanborn Solar and Energy Storage project exemplifies the vital role solar power plays in mitigating climate change and steering towards sustainable energy sources. Its magnitude underscores the transformative potential of renewable energy initiatives on both national and global scales.
