A new partnership between renewable investor Excelsior Energy Capital and battery manufacturer LG Energy Solution Vertech highlights the U.S. energy storage industry’s commitment to prioritizing a domestic supply chain.
The companies have entered into a multi-year agreement that will provide 7.5 GWh of fully integrated lithium-ion energy storage from LG Energy Solution’s energy storage division. LG Energy Solution Vertech for Excelsior’s standalone and hybrid energy storage projects in the United States.
Notably, the companies report that the projects will meet domestic U.S. content requirements and are expected to be delivered in April 2026.
The global energy storage systems (ESS) market is on the cusp of remarkable expansion, driven by a push for innovative, sustainable energy policies. For example, Wood Mackenzie predicts that the North American ESS market will grow from just 12 GWh in 2022 to 103 GWh in 2030.
The energy storage projects will utilize LG Energy’s containerized lithium-ion battery systems, which will be equipped with lithium iron phosphate (LFP) long cells designed to optimize energy efficiency and increase safety. The company said in September that it sees lithium iron phosphate (LFP) technology as one of four strategies to expand its business in the US market.
In October, LG launched Energy said it would start production of ESS batteries in the United States so that it could “maximize the benefits of policies supporting local production.”
