WEC Energy Announces Project to Demonstrate Long-Duration Organic Flow Battery Storage

WEC Energy Group announced that the company will lead a pilot project at its Valley Power Plant in Milwaukee to test a new form of long-duration energy storage.

WEC Energy Group is collaborating with EPRI, an independent, nonprofit energy research and development institute, and CMBlu Energy, the developer and manufacturer of the long-duration battery based in California and Germany.

This 1-to-2-megawatt-hour pilot project will be one of the first to test this type of energy storage system on the U.S. electric grid.

"One of our most important goals is to help shape the future of clean energy — testing technologies that could be true game changers," said Gale Klappa, executive chairman — WEC Energy Group. "On-demand energy storage is clearly a key component to an energy transition that is affordable, reliable and clean."

"The results of the pilot will provide key insights on how this innovation can be applied around the country," said Neva Espinzoa, EPRI vice president — energy supply and low-carbon resources. "We look forward to collaborating with WEC Energy Group and CMBlu Energy to help provide solutions to enable additional resilience through the energy transition."

"CMBlu Energy appreciates WEC Energy Group's commitment to guide the future of long duration energy storage for its customers and the electric power industry," said Ben Kaun, president — CMBlu Energy Inc. "This demonstration supports our roadmap of tailored products and manufacturing of Organic SolidFlow batteries in the United States."
