$1 Billion Solar+Storage Project Moving Forward

Solar energy storage.

The Gemini Project, a solar plus storage project commissioned by Nevada-based NV Energy will be the largest solar farm in the United States and possibly the world.

The project, which includes 690 megawatts (MW) of solar and 380 MW of four-hour lithium-ion battery storage, will exceed the solar farm in California that currently holds the record for the nation’s largest by over 100 MW.

The Nevada’s Public Utilities Commission gave the project a green light in December then the Bureau of Land Management released its final Environmental Impact Statement in early January, which started a 30-day public protest period.

The site is planned to be on 7,100 acres of federal land several miles outside of Las Vegas, and the White House has signaled that it will approve the siting, which will be the third time the current White House has approved solar siting on federal lands.

The Gemini Project is actually one of three new solar plus storage planned by NV Energy, the other two being Southern Bighorn (300 MW of solar with 135 MW of battery storage) and Arrow Canyon (200 MW of solar with 75 MW of battery storage). In all, the three projects will provide 1,190 MW of solar and 590 MW of storage, enough to power 230,000 homes.

According to David Scaysbrook, co-founder and managing partner of Quinbrook Infrastructure Partners, which will develop and build the Gemini Project along with Arevia Power, “Gemini plans to showcase at scale one of the most promising technological advances in renewable power. The project will demonstrate the ability to couple solar PV technology with battery storage to capture Nevada’s renewable solar resource to deliver low-cost power to NV Energy’s customers and keep the lights on long after the sun has set.”

When the Gemini Project is completed its power will be sold to NV Energy by a 25-year power purchase agreement at an anticipated cost of $38.44 per megawatt-hour. The project itself is estimated to cost slightly over $1 billion.
