Clean Power for the Win

The growth and success of renewable energy relies heavily on the ability to store energy. That’s where we come in. Our utility-scale battery energy storage systems (ESS) store power generated by solar or wind and then dispatch the stored power to the grid when needed, such as during periods of peak electricity demand. Our ESS solution increases the grid’s resilience, reliability, and performance while helping reduce emissions and mitigate climate change.  

Let's chat about your energy storage requirements and the advantages of our ESS.

It’s true, our batteries really are that good!

Our Difference

With complete control of the design, development, and manufacturing process, we provide a battery with superior technology and no compromises. We exceed all expectations regarding key measures such as energy density, safety, cycle life, and energy retention.

Rigorously Field-Tested Technology

The battery cell and module technology used for the ESS container is built on the established performance of our lithium-ion battery solutions developed for the commercial electric vehicle (CEV) market. With more than 17 years of experience manufacturing lithium-ion batteries and more than 30,000 battery systems deployed worldwide, our battery technology has demonstrated unparalleled field-proven reliability. All our batteries go through extensive third-party testing and validation.
