DTE Energy signs 6 GWh BESS supply deal with LG for eight Michigan projects

Detroit-based energy company DTE Energy has agreed to procure 6 GWh of battery energy storage systems (BESS) from LG Energy Solution Vertech as part of a US $1.6 billion investment to support the US state of Michigan’s grid and renewable penetration.

The supply agreement covers eight projects totaling 1.5 GW / 6 GWh, and they will be delivered over a two-year period according to both companies. DTE Energy estimates the agreement will generate US $2.3 billion in total economic impact, with the projects directly supporting 1,800 jobs at LG Energy Solution’s Holland manufacturing plant, along with more than 350 additional construction and operations roles.

DTE Energy didn’t reveal the locations or scope of its BESS projects. However, the company which serves some two million customers in the US state of Michigan, has just one operational BESS, a 14 MW / 56 MWh project from 2025.

Joi Harris, president and CEO of DTE Energy, is proud of the economic impact the eight projects will have on Michigan.

“DTE is committed to building a bright future for Michigan. By working with LG Energy Solution Vertech to bring more battery storage online through their Holland, Michigan manufacturing facility, we’re keeping Michigan at the forefront of technology and economic opportunity – creating good-paying jobs in communities while driving responsible growth, improving reliability for our customers and investing in clean energy solutions.”

LG Energy Solution will supply battery cells manufactured in Michigan, and other US and Canadian facilities to support the portfolio. Jaehong Park, CEO and president of LG Energy Solution Vertech, was thrilled to partner with DTE Energy.

“Michigan is a key US manufacturing region for our company, where many of our colleagues live and work. We’re thrilled to work with DTE to bring Michigan-made energy storage to our communities,” Park said. 

DTE Energy said the investment builds on 2025’s investment efforts where it spent nearly $4 billion to improve electric reliability, as the company claimed it “led customers to experience the best reliability in nearly two decades in 2025.” In Michigan alone, it spent approximately $2.9 billion last year. Earlier in the year, LG Energy Solution Vertech signed a 5 GWh agreement with Qcells, building on a 4.8 GWh deal in 2024 and underscoring the companies’ growing long‑term supply relationship in the US storage market.
