Flexible, Customizable Solutions
In the energy storage world, one size does not fit all


ESS Tech, Inc.’s (ESS’) solutions are configurable and assembled from the same proven, innovative core technology to meet the needs of utilities, independent power producers, AI data centers and other large energy users.
Energy Base™
Built on a modular platform, the Energy Base solution offers durations of 8-22 hours up to gigawatt-hour scale delivering the LDES capacity needed for a clean, resilient and reliable energy system.
Energy Center™
Created for utility-scale applications, this solution delivers eight hours of energy storage with a turnkey, containerized solutions.
The ESS advantage
Unlimited cycling
Most lithium-ion batteries are only designed for one cycle per day. ESS technology can be cycled continuously without limitation, as validated by extensive testing by the U.S. Department of Energy.
Zero degradation
Our batteries do not degrade with use and do not require augmentation, even when cycled continuously.
Wide range of operating temperatures
Our solutions operate in ambient temperatures from about -15°C to 50°C.
Lowest cost of service
ESS solutions offer the lowest overall cost of service for long-duration or multi-cycling requirements, especially in heavy use applications.
Made in America
ESS solutions are manufactured in Wilsonville, Oregon leveraging a largely domestic supply chain.
Long asset life
ESS core technologies have a design life of 25 years and have been extensively tested with the U.S. Department of Energy. Advanced cycle testing simulating over 4 decades of use demonstrated no degradation in performance.
Safe and sustainable
ESS systems are safe and sustainable, facilitating permitting and simplifying requirements for containment, handling and disposal.
