ESS becomes first non-lithium long-duration storage provider to receive major certification

March 27, 2024

Long-duration energy storage system manufacturer ESS Tech, Inc has become the first non-lithium LDES provider to be awarded the highest level of IEEE 693 certification, a widely accepted seismic rating for energy infrastructure.

ESS received the rating for its ‘Energy Center’ product line. The standard provides assurance that the Energy Center product line qualifies for deployment as critical infrastructure across the US.

Testing was conducted by the Pacific Earthquake Engineering Research Center at the University of California, Berkeley, and included a shake table test of ESS battery module assemblies and an evaluation of Energy Center design.

“We are committed to providing resilient, high-quality energy storage solutions that customers can rely on when they need them most, especially during extreme weather or natural disasters,” said ESS chief technology officer Dr. Julia Song. “Achieving IEEE 693 certification for the Energy Center follows rigorous testing and demonstrates the key role for ESS technology in the critical infrastructure powering the clean energy future.”

ESS CEO Eric Dresselhuys added: “Thanks to our engineering team’s efforts, we are continuing to develop, deploy and validate cutting edge long-duration energy storage solutions that provide the secure, resilient power that our customers require. Achievement of IEEE 693 follows rigorous testing and is an attestation to the quality and reliability of ESS solutions.”
