In a significant development for North America’s clean-energy industry, LG Energy Solutions Canadian arm has hit the milestone of producing one million battery cells at its Windsor, Ontario facility, only three months after commencing full-scale production — a testament to rapid operational scaling and rising momentum in regional battery manufacturing.
The milestone was reached through high levels of automation and strict, multi-step quality control measures that ensure each cell meets performance and reliability standards. These cells, based on lithium iron phosphate (LFP) chemistry, are primarily designed for energy storage systems (ESS) — a market that is growing alongside traditional electric vehicle (EV) battery demand.
NextStar Energy, the Canadian production unit that achieved this output, has secured key international certifications including ISO 14001 for environmental management, ISO 45001 for occupational health and safety, and IATF 16949 for automotive quality standards — underlining its commitment to global manufacturing excellence.
The Windsor facility, which has received over CAD 5 billion in investments and employs more than 1,300 workers so far, is integral to Canada’s growing role in North America’s EV and clean energy supply chains. It represents the first large-scale battery manufacturing plant in the country, a project that has been central to broader efforts to build domestic capabilities in battery production.
In parallel with this production achievement, LG Energy Solution recently announced plans to acquire full ownership of NextStar Energy by purchasing the remaining stake formerly held by Stellantis. This transition — subject to regulatory approvals — is intended to give LG greater flexibility to expand its customer base and respond to shifts in market demand, especially in the ESS sector.
Under the new ownership structure, Stellantis will remain a committed customer, continuing to source batteries from the Windsor facility even as LG Energy Solution positions the plant as a key strategic hub for both ESS and future EV battery production in North America.
