NextStar Energy (NSE) has received its Occupancy Permit, marking the official completion of construction. This milestone brings the $5-billion NSE facility one step closer to ramping up operations for cell manufacturing this year.
NSE, a joint venture between LG Energy Solution and Stellantis, is Canada’s first large-scale battery manufacturing facility. Located in Windsor, Ontario, NextStar Energy is dedicated to the development and innovation of sustainable and efficient energy solutions, empowering the future of mobility.
“This achievement is the direct result of a shared vision, 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.”
The facility is a state-of-the-art battery manufacturing plant that is capable of an annual production capacity of up to 49.5 gigawatt hours. Core operations include electrode production, cell formation and assembly, and module assembly. NSE has hired over 950 full-time employees to date and has committed to creating 2,500 local jobs.
“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, added Mayor Dilkens, “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.”
Construction of the massive 4.23 million-square-foot site began in 2022 and progressed rapidly. More than 9,000 Canadian trades workers contributed over 8.4 million work hours to bring the project to life. Today, the site is home to 11 buildings: two main manufacturing facilities – Cell and Module – and nine support buildings, including a recycling centre and safety testing laboratory.
While minor construction activities continue in non-operational areas, the facility itself is fully approved for safe occupancy and ready for production.
