Missouri Municipal Utility Commits to 216Mh of Eos Zinc-based Battery Storage in Springfield
Eos Energy Enterprises has signed a new customer agreement with City Utilities (CU) of Springfield to provide 216 MWh of zinc-based energy storage for two project sites in Missouri.
Eos by contract will provide 216 MWh, 36 MW by six-hour duration, to support City Utilities’ expansion goals and ability to maintain planning reserve margin (PRM) of over 36 percent by 2026.
The project will utilize Eos’ Z3TM technology, a grid-scale, U.S. manufactured alternative to lithium-ion, to develop CU’s energy storage capabilities, proceed with its expansion goals and strengthen reliable energy delivery to the community it serves.
The project supports Eos’ aim to deliver innovative, sustainable energy storage solutions and further expand into the municipal customer segment.
“This new agreement with City Utilities demonstrates a great partnership designed to deliver safe technology to the citizens of Springfield, while achieving key deliverables for the municipality,” said Justin Vagnozzi, Senior Vice President of Global Sales at Eos, in a statement. “Our uniquely non-flammable battery energy storage system technology will be an asset for CU as they expand their capabilities and leverage a reliable, safe U.S.-made storage system to manage rising energy demands.”
Last year, Eos Energy Enterprises announced a $500 million expansion program to scale up long-duration energy storage capacity with zinc-based components, The Project AMAZE—American Made Zinc Energy –is aiming for 8 GW by 2026 using the Eos Z3 system.
Lithium-ion chemistry dominates the battery storage market, particular in short-duration applications such as electric vehicles. Rival technology firms are exploring longer duration and less fire-risk chemistries such as zinc and, on an early research level, sodium ion.
