LG Energy Solution's U.S. subsidiary, LG Energy Solution Vertech, has signed a $1.8 billion supply agreement with DTE Energy to develop Michigan-made battery energy storage systems (ESS) across the state, in a deal covering 6 gigawatt-hours (GWh) of storage capacity, the company said Thursday.

Under the agreement, LG Energy Solution Vertech will supply battery energy storage systems for eight projects over the next two years. The projects will provide a combined 1.5 gigawatts, or 6 gigawatt-hours, of battery storage capacity aimed at enhancing grid reliability and supporting clean energy deployment.

The systems will store electricity during periods of excess generation and supply power during peak demand, helping reduce strain on the grid and improving operational efficiency.

“Michigan is a key U.S. manufacturing region for our company, where many of our colleagues live and work,” said Park Jae-hong, CEO and president of LG Energy Solution Vertech. “We’re thrilled to work with DTE to bring Michigan-made energy storage to local communities.”
