Primergy Solar, a U.S.-based utility-scale and distributed solar and storage company has entered a sole battery supply agreement with Contemporary Amperex Technology Limited (CATL) to develop a 690 MW solar and 1,416 MWh storage project called Gemini in Nevada in the United States.

Gemini will be one of the largest operational solar and storage projects in the U.S, worth a total of $1.2 billion.

Primergy, which has portfolios of over 8 GW of solar and battery energy storage projects in development, construction, and operations over 17 different states in the U.S., has completed a comprehensive procurement process and selected several globally leading equipment suppliers and construction partners for the Gemini project.

The company said it has designed an innovative direct coupling system for the project, aiming to maximize efficiency by teaming up with CATL’s storage system.

CATL will supply Primergy with EnerOne, a modular outdoor liquid cooling energy storage system with long service life, high integration, and a high degree of safety. EnerOne solutions utilize advanced lithium phosphate chemistry and hence have been selected for Gemini by Primergy for it meets the company’s requirements for safe and reliable operations at its sites.

With a cycle life of up to 10,000 cycles, the LFP (lithium ferro-phosphate) based battery product is expected to contribute to the safe and reliable operation of the Gemini project.

“CATL is a technology leader in the battery industry, and we are pleased to partner with them on the Gemini Project and showcase CATL’s advanced EnerOne storage solution,” said Ty Daul, Chief Executive Officer of Primergy Solar.

“The future of our country’s energy reliability and resiliency relies on the mass deployment of battery storage capacity that can supply consistent power back into the grid when it’s needed most,” he added.

According to a report published by Wood Mackenzie, CATL led the expansion outlook, amongst the Chinese battery manufacturers, with an operating and planned capacity of 800 GWh by 2030.

APG, a Netherlands-based pension asset manager, agreed to acquire 49% equity ownership in the Gemini project from Quinbrook Infrastructure Partners, an investment manager focused exclusively on the new infrastructure needed for the energy transition, and its portfolio company Primergy.
