Excelsior Energy Capital, a leading renewable energy infrastructure investor, announced a multiyear, 7.5 GWh reservation agreement with LG Energy Solution Vertech, a global leader in energy storage system integration. Through the multiyear agreement, LG Energy Solution Vertech will provide Excelsior with a reliable supply of domestically manufactured, high-quality battery energy storage systems (BESS) to support its growing portfolio of standalone and hybrid energy storage projects across the United States.
Under the partnership, which begins in 2026, the battery systems will be manufactured at LG Energy Solution’s advanced production facilities in the U.S., providing a more certain and secure supply chain for Excelsior’s projects. These products will be complemented by LG Energy Solution Vertech’s integration and lifecycle services.
This shared commitment provides Excelsior with enhanced protection from trade-related uncertainties and supply chain risk, offers price and availability assurances, and advances the company’s commitment to fostering American clean energy jobs and manufacturing.
“Excelsior and LG Energy Solution Vertech share a common vision to build battery energy storage systems and projects that stand the test of time – both in the quality of manufacturing and operations of the systems and through our ongoing work in providing reliable and safe sources of on-demand power to the U.S. grid,” said Anne Marie Denman, Co-Founder and Partner of Excelsior. “As one of LG Energy Solution Vertech’s customers for its domestic supply of BESS, we have secured access to a reliable and diversified supply chain, steady pricing, and leading-edge technology. This allows us to continue to serve as a reliable partner to our project stakeholders, delivering project execution certainty by nearshoring the largest portion of the capital expenditure for our battery projects.”
