Primergy Solar LLC, a developer, owner and operator of utility and distributed scale solar and storage, has entered a sole battery supply agreement with Contemporary Amperex Technology Co. Ltd. (CATL) for the $1.2 billion Gemini Solar+Storage Project outside of Las Vegas.
Once completed, Gemini will be one of the largest operational solar+storage projects in the U.S., with a 690 MW AC/966 MW DC solar array and 1,416 MWh storage capability.
Earlier this year, Primergy completed a procurement process and selected equipment suppliers and construction partners for the project.
“With Primergy’s industry-seasoned team, their in-house capability in development, construction and management of long-term assets and CATL’s innovative battery technologies,” says Tan Libin, vice president of CATL. “We believe our cooperation on the Gemini Solar Project will set a great example for large-scale electrochemical energy storage applications, thus promoting global drive towards carbon neutrality.”
Primergy designed a DC-coupled system for the project, which will maximize efficiency from the teaming of the solar array with the CATL storage system. CATL will supply Primergy Solar with EnerOne, a modular outdoor liquid cooling battery energy storage system. With a cycle life of up to 10,000 cycles, the LFP-based battery product will contribute to the operation of the Gemini project. Primergy selected the EnerOne solution for Gemini because it utilizes advanced lithium phosphate chemistry, which meets Primergy’s requirements for safe and reliable operations at its sites.
