Gemini Solar + Storage, Nevada (2023)
In Clark County, Nevada, the Gemini plant combined roughly 690 MW of solar with 380 MW / 1.4 GWh of battery storage under a power purchase agreement with NV Energy. It was then one of the largest solar-plus-storage plants in the U.S.
Established a template for desert mega hybrid plants delivering power into evening hours.
Proved that pairing utility-scale solar with storage at this size pencils out economically.
Gemini used the same 1.4 GWh storage capacity as Sterling, showing the configuration already works at scale.
