ESS Inc. Contracts With Enel Green Power España to Deliver 17 Energy Warehouse™ Long-Duration Iron Flow Battery Systems
WILSONVILLE, Ore., Sept. 23, 2021 (GLOBE NEWSWIRE) -- ESS Tech, Inc. (“ESS Inc.”, “ESS” or the “Company”), a manufacturer of long-duration iron flow batteries for commercial and utility-scale energy storage applications, announced that it has closed an order with Enel Green Power España to deliver 17 ESS Energy Warehouse™ iron flow battery systems.
The long-duration batteries will be used to support a solar farm in Spain as a part of a broader EU-wide engagement, providing resilience for the local power grid. With a combined capacity of 8.5 MWh, the ESS systems will be among the largest battery storage resources in Spain.
“We are 100% committed to energy storage as an essential complement to our expanding portfolio of renewable energy projects,” said Pasquale Salza, Head of Long-Duration Storage and Hybrid Systems for Enel Green Power. “With this project, we’re going to assess and validate the ESS flow batteries, which we selected due to their right combination of long-duration capacity, long-life performance, environmental sustainability and safe operation.”
“Our systems passed a 6-month technology and company readiness assessment – meeting Enel Green Power España stringent performance, durability and cost requirements to become an Officially Qualified Global Vendor. Another key factor in their decision is that our batteries are covered by a comprehensive insurance plan underwritten by Munich Re, the world’s largest reinsurance company,” said Eric Dresselhuys, CEO of ESS Inc.
ESS is collaborating with several key partners on this project, including Loccioni, a global systems integrator with projects in over 45 countries. The Company is also working with Enertis, a global consulting and engineering firm headquartered in Spain.
