The largest solar plus battery energy storage project in the U.S. is now operational in Clark County, Nevada. Built by Primergy Solar and Quinbrook Infrastructure Partners, the Gemini project will deliver power to Las Vegas and other regional communities.

By generating up to 690 MW, the 1.8 million solar panels can power approximately 10% of Nevada’s peak power demand. The solar arrays are co-located with 380 MW of four hour battery storage to provide customers with 1,400 MWh of clean, reliable power after sundown. A DC-coupled storage configuration enables the energy storage system to charge directly from the solar panels to enhance efficiency and maximize on-site capture and storage of solar energy.

Gemini incorporates shingled bifacial Performance 5 UPP solar modules supplied by Maxeon Solar Technologies that are engineered with materials innovations that range from encapsulants to aerospace-grade conductive adhesives. These materials protect cells and minimize power loss from exposure to the extreme environmental conditions in Nevada, including arid deserts and vast daily and seasonal temperature ranges.

The newly commissioned 5,000 acre Gemini system is expected to help reduce carbon emissions by 1.5 million tons annually.
