• NextStar Energy facility is officially complete after receiving Occupancy Permit.
• The company prepares to begin cell production.

In its latest milestone, NextStar Energy, a joint venture between LG Energy Solution and Stellantis, has received its Occupancy Permit for its Windsor, Ontario facility, marking the official completion of construction. The company now shifts its focus to final preparations ahead of launching full-scale operations later this year.

Since breaking ground on its 392,980㎡ (4,230,000 ft²) facility in 2022, construction has advanced at an unprecedented pace. More than 9,000 Canadian trades workers have contributed 8.4 million work hours to complete the build — a testament to collaboration across government, industry, and community partners.

The site’s 11 buildings include two main manufacturing plants for cell and module production, and nine ancillary facilities ranging from a recycling center to a safety testing laboratory. While minor construction activities continue in non-operational areas, the facility is now fully approved for safe occupancy and ready for the next phase – production.

With construction now officially complete, the Windsor facility is poised to strengthen both its operations and the broader Canadian battery ecosystem and economy. Having already hired over 1,000 full-time employees, the company is delivering on its promise to power a new era of clean energy manufacturing in Ontario, Canada.

“This achievement is the direct result of a shared goal, effective partnership, and incredible hard work of everyone involved,” said Danies Lee, CEO of NextStar Energy. “As we transition from construction to operations, I am deeply grateful for the collaboration between our partner companies LG Energy Solution and Stellantis, our construction partner Alberici-Barton Malow, the City of Windsor, the provincial and federal governments, and all who have supported our project to be completed safely and on schedule.”

“Completion of construction and the granting of the Occupancy Permit marks a major milestone for the game-changing NextStar Energy battery manufacturing facility in Windsor,” said Windsor Mayor Drew Dilkens. “The $5-billion investment has placed us at the forefront of electrification, and our collective commitment to collaboration, land development, infrastructure, and job creation continues to drive new investments and build the foundation of future growth and development for Windsor and Essex County. Windsor has been identified as one of the fastest growing communities to watch in Ontario and Canada. NextStar Energy is a major component of our unprecedented growth and evolution. Despite economic uncertainties posed by U.S. tariffs, everyone connected to this project has remained focused on the long game and supporting the positive momentum this build has caused, as well as the incredible spinoff impacts for the supply chain that is growing in lockstep with the plant. Together, we are Building Windsor’s Future with a focus on investment, growth, and sustainability. Congratulations to the teams powering this build on this significant progress.”
