Gemini is located thirty minutes outside of Las Vegas and with its 1.8 million solar panels, will power about 10% of Nevada’s peak power demand.
Primergy and Quinbrook Infrastructure Partners announced that the Gemini solar-plus-storage project outside of Las Vegas, Nevada is now operational.
The 1.8 million solar panels are expected to generate up to 690 MW and they’re co-located with 380 MW of 4-hour battery energy storage (1,400 MWh). Using a DC-coupled storage configuration enables the batteries to be charged directly by solar, thus increasing efficiency.
In April 2022 the two companies announced that they had closed on a landmark deal of $1.9 billion in debt and tax equity financing project. The debt financing consists of $1.3 billion in credit facilities and $532 million in tax equity commitments, with the tax equity commitments provided by Truist Bank and Bank of America.
In constructing the project, which is on federal land, Primergy reports that it “created and implemented an unprecedented framework for ecosystem management” by leaving vegetation in place and using a tracker system that follows the natural undulations of the ground. The company estimates that it was able to reduce the project’s land footprint by over 20%.
During construction the project reportedly created approximately 1,300 union and prevailing wage jobs and contributed approximately $463 million to Nevada’s economy.
“Gemini creates a blueprint for holistic and innovative clean energy development at mega scale, and we are proud to have brought this milestone project to life and to have delivered so many positive impacts across job creation, environmental stewardship, and local community engagement,” said David Scaysbrook, co-founder and managing partner of Quinbrook.
The project uses Maxeon Solar Technologies’ solar modules that use bifacial mono-PERC solar cells made on large format 8-inch G12 wafers. Maxeon reports that these modules offer efficiency of over 21%, enhanced shade tolerance, and power ratings of up to 625 watts. The modules are mounted on trackers from Array and Ojjo, which are specifically designed to withstand harsh desert environments and high wind speeds with a patented wind-mitigation system.
Primergy selected Kiewit Power Constructors Co. as Gemini’s engineering, procurement and construction (EPC) partner and IHI Terrasun Solutions as the integrator for the project’s 380 MW/1,520 MWh lithium-ion battery.
NV Energy signed a 25-year power purchase agreement for the energy produced by the Gemini plant. It is expected to meet 10% of Nevada’s peak energy needs.
Primergy Solar is a developer, owner and operator specializing in utility-scale solar PV and battery storage projects across the U.S. Quinbrook Infrastructure Partners is an investment manager focused on the infrastructure needed to drive the energy transition in the UK, U.S., and Australia.
