Solar and battery storage project by Primergy


Southern Nevada, United States

Year acquired

Gemini, at the time of signing its Power Purchase Agreement, was believed to be the world’s largest solar PV and battery storage project announced to date.

The project features a 690MW solar array and a 380MW battery system capable of storing more than 1,400 megawatt hours of solar power. Gemini is scheduled to be constructed on federal land 25 miles (40 kilometers) north of Las Vegas by the end of 2023.

Gemini is designed to bring low-cost renewable power to Nevada and is expected to feature over 2.5 million solar modules installed on 7,100 acres of land dedicated to solar power and advanced battery storage.

The project is designed to produce low-cost renewable power for Nevada and is projected to bring over $450 million of financial stimulus to the state’s economy. All of Gemini’s output is covered by a 25 year Power Purchase Agreement with NV Energy, a subsidiary of Berkshire Hathaway.

Target Outcomes
  • Largest solar and BESS project in US history as at May 2020
  • Potential to generate power equivalent to the demand of all Las Vegas residents
  • Work closely with the local Moapa Tribes, National Park Services and US Fish and Wildlife Services
  • Provide innovative new habitat preservation plan for the Desert Tortoise, a threatened species
  • 2,200,000 MWh p.a. renewable energy production
  • 260,000 homes powered
  • 1.5 million metric tons p.a. CO2-e displaced
  • 2,500 jobs during construction
  • US$450 million regional economic impact
