Fluence Energy and Excelsior Energy Capital have announced plans to deploy 2.2 GWh of battery storage projects across US starting in 2025. These projects will feature batteries, modules, and supporting systems manufactured domestically. Under the agreement, Fluence’s Gridstack Pro product line will be deployed by Excelsior to deliver firm capacity and flexible power to enhance the resilience of the U.S. electricity grid.
Furthermore, the projects are expected to strengthen a domestic supply chain for crucial clean tech manufacturing in the US and directly support American jobs while expanding battery storage production capacity. Battery cells for projects exceeding 2 GWh will primarily be manufactured in Tennessee and battery modules will be manufactured by Fluence in Utah.
In April 2024, Excelsior Energy Capital secured a multiyear deal to purchase 2 GW of solar modules from Heliene, with most panels to be produced at Heliene’s Mountain Iron, Minnesota facility and a new plant near Minneapolis-St. Paul, US. This agreement aims to mitigate supply chain risks for Excelsior and marks a significant expansion for Heliene, which is focussed on U.S. growth.
