Quick Takeaways
- NextStar Energy Battery Cell Production achieved a major manufacturing milestone.
- Scaling Up NextStar Energy Battery Cell Production in Windsor.
On February 12, NextStar Energy Battery Cell Production achieved a major manufacturing milestone as the company rolled out its one-millionth battery cell at the CAD 5 billion Windsor, Canada facility. This landmark underscores the accelerated industrial ramp-up at the site, which has expanded its workforce to 1,300 employees since initiating commercial operations in November 2025. The Windsor facility is increasingly recognized as a foundational asset within Canada EV battery manufacturing and a strategic node in North America?s electric vehicle battery cells supply network.
The Windsor battery gigafactory rapidly increased production volumes within months of commencing commercial manufacturing. Crossing the one-million-unit threshold reflects process stabilization, yield optimization, and synchronized capacity planning aligned with growing demand for Stellantis EV batteries and broader regional electrification initiatives. The facility?s scaling trajectory aligns with North America?s objective to strengthen domestic battery production capabilities and enhance supply chain resilience by reducing dependence on offshore sourcing.
Commercial cell manufacturing began in November 2025, followed by swift workforce expansion to 1,300 personnel. This growth illustrates the capital intensity and advanced manufacturing complexity associated with electric vehicle battery cells production. The milestone highlights the integration of high-throughput automation systems, precision quality control, and localized technical expertise, reinforcing Canada?s EV ecosystem while supporting sustainable industrial development and long-term job creation.
It was recently confirmed that LG Energy Solution will assume full ownership of NextStar Energy, with Stellantis continuing as a key customer under the revised structure. With this transition, the Windsor facility is positioned to benefit from LG Energy Solution acquisition-driven synergies, including proprietary cell chemistry innovation, vertically integrated supply chain capabilities, and global-scale battery engineering expertise. The ownership change is also expected to broaden the plant?s commercial scope beyond purely automotive applications.
Under complete ownership by LG Energy Solution, the Windsor operation will expand into ESS battery cells production alongside EV output. The facility is set to address rising demand in the energy storage system batteries segment, supporting applications such as grid reliability enhancement, renewable energy integration, and commercial-scale storage deployments. ESS battery cells production is scheduled to scale progressively through 2026, establishing the Windsor battery gigafactory as a diversified manufacturing hub serving both electric mobility and stationary energy storage markets.
Key developments at a glance:
The achievement strengthens NextStar Energy Battery Cell Production as a pivotal contributor to North America?s electrification strategy. With LG Energy Solution?s full ownership and Stellantis maintaining its role as a principal customer, the Windsor plant is positioned to advance electric vehicle battery cells manufacturing capacity while accelerating expansion into energy storage system batteries, reinforcing Canada?s competitiveness within the global battery value chain.
