Introduction
Indiana has just landed its largest single investment in history: a $3.5 billion joint venture between General Motors and Samsung SDI to build a state-of-the-art EV battery plant. Located on a 680-acre site in New Carlisle, St. Joseph County, this project will create more than 1,600 high-quality manufacturing jobs and produce enough battery cells to power hundreds of thousands of electric vehicles by 2027. As the auto industry races toward electric transportation, Indiana’s bold commitment signals a new era of clean-energy manufacturing in the Midwest. Read on to explore how this record-breaking investment came together, what it will mean for Hoosiers, and why it matters for America’s EV future.
The Genesis of the Joint Venture
In April 2023, Michigan-based GM and Korea-based Samsung SDI announced they would partner to form a joint venture focused on producing advanced battery cells and modules for electric vehicles. That agreement laid the groundwork for what has become Indiana’s largest economic investment ever businessfacilities.com. GM brings decades of auto-manufacturing expertise and a growing lineup of electric models, while Samsung SDI contributes leading battery-technology know-how under its premium PRiMX brand greaterkokomo.com. Together, the two companies aim to secure the supply chain for EV batteries in North America and accelerate the shift away from fossil-fuel vehicles.
Why Indiana?
State and local leaders worked for more than a year to attract the project. Key factors that tipped the scales in Indiana’s favor included:
- Strategic Location: New Carlisle lies within driving distance of GM’s existing assembly plants in Michigan and Ohio, reducing transport costs.
- Available Land: A 680-acre megasite offered ample space for the 2.5 million-square-foot facility and future expansions.
- Infrastructure: Proximity to major highways, rail lines, and a skilled manufacturing workforce made Indiana a natural choice.
- Incentives: The Indiana Economic Development Corporation (IEDC) and St. Joseph County provided a performance-based incentive package, including tax abatements and workforce grants, to support construction and job creation businessfacilities.com.
Governor Eric J. Holcomb hailed the deal as “the most significant single EV investment in the State of Indiana and the largest project investment in St. Joseph County in the past 75 years” sbrchamber.com.
The Scale of the Investment
At $3.5 billion, this joint venture eclipses all prior private-sector investments in Indiana. The funds will cover:
- Land Acquisition and Site Preparation: Clearing and grading the 680-acre plot near Larrison Boulevard and Indiana 2.
- Factory Construction: Building the main production halls, quality labs, and support facilities.
- Equipment and Machinery: Installing cutting-edge production lines capable of manufacturing nickel-rich prismatic and cylindrical cells.
- Workforce Development: Training and certifying more than 1,600 new employees in specialized battery-manufacturing roles.
Operations are slated to begin in 2026, with full production capacity expected by 2027 at 27 GWh annually—enough to supply batteries for roughly 500,000 EVs per year samsungsdi.comtheverge.com. Subsequent expansions could push capacity up to 36 GWh.
Job Creation and Economic Impact
This project promises to transform the local economy:
- Direct Jobs: Over 1,600 manufacturing positions, including cell technicians, quality-control analysts, and maintenance engineers.
- Indirect Jobs: Estimates suggest each direct job will support 2–3 additional roles in construction, logistics, and local services.
- Wage Growth: Average factory wages in the region are projected to rise as the plant attracts skilled talent.
- Small-Business Boost: Local suppliers of parts, tooling, and maintenance services will see new contracts.
By anchoring such a large-scale employer, St. Joseph County expects long-term tax revenue growth and increased consumer spending at nearby businesses, from restaurants to retail shops.
Technology and Capacity
The New Carlisle plant will adopt Samsung SDI’s PRiMX battery technology—a nickel-rich chemistry known for higher energy density and longer cycle life greaterkokomo.com. Key production details include:
- Initial Capacity: 27 GWh per year, scaling to 36 GWh with future expansions.
- Cell Types: A mix of prismatic and cylindrical cells to support GM’s diverse EV lineup.
- Automation: Advanced robotics for electrode coating, cell assembly, and quality inspection.
- Sustainability: Closed-loop water systems and energy-efficient processes to reduce environmental impact.
This focus on cutting-edge technology underscores GM’s and Samsung SDI’s commitment to leading the EV market in North America.
Incentives and Local Commitments
To secure the investment, Indiana offered an attractive incentive package:
- Tax Abatement: A decade-long, 100 percent property tax break on the plant’s value.
- Infrastructure Fee: A negotiated $4.5 million annual fee paid by GM to support local roads, sewers, and water systems.
- Workforce Grants: State and county funding for apprenticeship programs and technical training at nearby Ivy Tech Community College.
These measures strike a balance between reducing upfront costs for the companies and ensuring that the local community benefits from improved infrastructure and workforce readiness theverge.com.
Comparison to Other EV Investments
Indiana’s deal follows a wave of major EV investments in the U.S.:
- Stellantis & Samsung SDI in Kokomo: A $2.5 billion gigafactory announced in 2022, backed by a $7.54 billion DOE loan, to supply batteries for Jeep & Ram EVs apnews.com.
- Ford’s BlueOval City in Tennessee: A $5.6 billion megasite combining F-150 Lightning assembly and battery production, the largest investment in Tennessee history en.wikipedia.org.
- GM Ultium Cells in Ohio & Michigan: GM’s own battery plants under the Ultium joint venture with LG Energy Solution, totaling over $7 billion across both states.
Indiana’s $3.5 billion project cements the Midwest’s role as America’s EV battery hub, joining these high-profile facilities that together aim to meet automakers’ ambitious electrification goals.
Challenges and Opportunities
While the investment promises major benefits, it also brings challenges:
- Workforce Recruitment: Filling 1,600 specialized roles requires aggressive outreach, visa sponsorship, and training programs.
- Supply Chain Security: Ensuring reliable access to nickel, cobalt, and other raw materials amid global demand pressures.
- Market Timing: Aligning plant ramp-up with EV adoption rates, which have faced headwinds due to high vehicle prices and charging infrastructure gaps barrons.com.
Yet these challenges also open opportunities for:
- Education Partnerships: Expanding curricula at local colleges to include battery-manufacturing and materials science.
- Supplier Development: Encouraging local firms to specialize in battery components, from separators to anode materials.
- Public-Private Collaboration: Leveraging state and federal grants for clean-energy innovation and infrastructure improvements.
Indiana’s Clean-Energy Future
The New Carlisle battery plant aligns with broader goals to reduce carbon emissions and expand U.S. EV production. By hosting one of the largest EV battery facilities in the country, Indiana:
- Strengthens National Security: Domestic battery production reduces dependence on foreign supply chains.
- Advances Climate Goals: Supporting automakers’ targets for zero-emission vehicle sales.
- Promotes Economic Resilience: Diversifying the state’s manufacturing base beyond traditional automotive parts.
With President Biden’s Inflation Reduction Act and infrastructure funding, states that secure battery plants stand to gain from tax credits and grants that lower project costs and accelerate clean-energy deployment.
What Comes Next?
As ground breaks later in 2025, stakeholders will watch:
- Construction Timeline: Completion of civil work, building shell, and installation of production lines.
- Hiring Milestones: First waves of technicians, engineers, and support staff joining training programs.
- Production Kickoff: Initial cell production slated for 2026, with full-rate manufacturing in 2027.
- Community Engagement: Ongoing dialogue with local residents on traffic, housing, and environmental monitoring.
Successful execution will set a template for future EV investments in the heartland and beyond.
