Sited just outside Las Vegas, the $1.2-billion Gemini project is billed as the largest of its kind currently under construction in the US. When completed and operational in 2023, Gemini would boast a 690 MW solar array paired with 1,416 MWh of energy storage. That would enable it to power over 400,000 households during peak periods, avoiding some 1.5 million tons of CO2 annually. That's noticeably larger than similar projects like the Manatee Energy Storage Center in Florida completed at the end of 2021, which has 409 MW of generation capacity and 900 MWh of energy storage capacity. Specifically, CATL would supply the Gemini project with its EnerOne modular outdoor liquid cooling battery energy storage systems. Less than a month ago, the Chinese battery supplier also grabbed a Master Supply Agreement to provide North Carolina’s FlexGen with 10 GWh of its EnerC battery systems over a three-year period.
