ESS Global Fleet Achieves Operational Milestone Surpassing 2 GWh of Transacted Energy
Additional Energy Center™ products are delivered to Florida utility and product line achieves safety and operational certifications.
ESS Tech, Inc. (ESS) (NYSE: GWH), a leading manufacturer of iron flow long-duration energy storage systems (LDES) for commercial and utility-scale applications, today announced that the company's global fleet of LDES solutions has transacted nearly 2.5 GWh of transacted energy. This operational milestone was achieved as the company continues to deliver and begin commissioning of its Energy Center™ products and earns new safety and operational certifications, underscoring the company's leadership in the LDES industry.
In December, ESS completed construction and initial testing of two Energy Center™ units for Portland General Electric and began shipment of Energy Center™ systems to a major Florida utility. Eight Energy Center™ systems have now been delivered for the Florida project. Both projects are expected to become fully operational this year.
"These milestones illustrate the value that ESS systems are delivering to our customers and our steady progress in scaling the business," said Hugh McDermott, ESS SVP of Business Development. "The Energy CenterTM is our 8+ hour product and we continue to build on the evolution of our systems. We're now looking to add 12+ hour projects with our Energy BaseTM product line while continuing to grow the overall ESS fleet to provide safe and sustainable LDES, including delivering green baseload, for decades to come."
Underscoring the safety and sustainability of the solution, the Energy Center™ product line recently earned industry-leading certifications including ETL certification to the UL 9540 standard. UL 9540 is a comprehensive safety standard for grid-connected energy storage systems which affirms the safety of the battery system and its environmental performance. The standard covers stationary energy storage systems for both outdoor and indoor installations.
To facilitate deployment and operation of ESS products, the Energy Center™ product line also recently passed the Modular Energy System Architecture (MESA) Standards Alliance's MESA-Device profile test, the first energy storage technology to demonstrate compliance, and has also received SunSpec Alliance Modbus Certification.
The Energy Center's software was rigorously assessed against the MESA-Device profile test to confirm its ability to reliably communicate and share data between systems at a project site and to enable clean, predictable command and control operation.
These new certifications are in addition to IEEE 693-High certification, which the Energy Center product line received in 2024. IEEE 693 is a widely accepted seismic rating for energy infrastructure. ESS was the first non-lithium LDES provider to receive the certification, providing assurance that the Energy Center product line qualifies for deployment as critical infrastructure in seismically active regions.
If you would like to learn more about these developments, including information about ESS' new Energy BaseTM product line, representatives from ESS will be exhibiting at Intersolar North America in San Diego from February 25-27 in booth number 2405.
