EnerSys to Build $500M Defense-Focused Lithium Cell Factory in South Carolina with $150M DOE Grant





EnerSys Refines Plans for Defense Lithium Cell Manufacturing Facility

EnerSys Refines Plans for Defense-Focused Lithium Cell Manufacturing Facility with DOE Support

Key Highlights

  • Strategic Shift: EnerSys has updated its plans for a new U.S. lithium cell manufacturing facility in Greenville, South Carolina, refocusing the project on defense, aerospace, and critical industrial applications where a secure domestic supply chain is essential.
  • DOE Grant: The company has been awarded a revised grant from the U.S. Department of Energy (DOE) of approximately \$150 million, subject to final documentation and customary conditions.
  • Total Investment: EnerSys estimates the total net investment for the facility at approximately \$500 million.
  • Incentives: South Carolina and Greenville County have awarded EnerSys a comprehensive incentive package valued at about \$200 million, including short- and long-term incentives.
  • Production Capacity: The facility will have an initial production capacity of about 1 gigawatt hour (GWh), purpose-built to meet specialized defense requirements.
  • Board Approval: EnerSys’ Board of Directors has formally approved the investment and development plan.
  • Technology Partnership Change: EnerSys is transitioning away from its technology relationship with Verkor, and does not expect Verkor to be the project’s technology partner going forward.
  • Timeline: Construction is expected to begin in the first half of fiscal year 2028, with full production anticipated approximately three years after construction commences.

Investor-Relevant Details

EnerSys (NYSE: ENS), a global leader in stored energy solutions, has refined its manufacturing strategy for its planned U.S. lithium cell facility. The updated focus caters specifically to defense-critical applications, ensuring the facility meets requirements for secure, Foreign Entity of Concern (FEOC)-compliant lithium-ion cells. This move is expected to serve customers who demand U.S.-based production, and is anticipated to generate incremental demand beyond EnerSys’ current business.

Significant Funding and Incentives

The facility’s development is substantially underpinned by federal, state, and local funding:

  • DOE grant: \$150 million (subject to final documentation).
  • South Carolina and Greenville County incentives: \$200 million.
  • Total net investment: \$500 million.
  • Funding sources: Federal, state, local incentives, and operating cash flow.

Strategic and Competitive Impact

EnerSys’ Board has officially approved the investment. The company expects the facility to deliver incremental revenue opportunities, as it is designed for customers requiring domestic production for defense-related applications. This aligns with EnerSys’ EnerGize strategic framework, supporting long-term shareholder value.

Notably, EnerSys is ending its technology partnership with Verkor, opting instead to leverage longstanding relationships within its existing aerospace and defense supply base. This change is important for investors, as it reduces reliance on external technology partners and strengthens control over the facility’s specialized technology and compliance requirements.

Construction and Production Timeline

  • Construction Start: Expected in the first half of fiscal year 2028 (subject to approvals).
  • Full Production: Approximately three years after construction starts.
  • Capacity: Initially 1 GWh, tailored for defense customers.

Potential Impact on Shareholders

  • This project is a major, price-sensitive development, as it represents a significant capital investment and strategic shift into defense-focused lithium cell manufacturing.
  • The DOE grant and large incentive package reduce financial risk and support long-term profitability.
  • Incremental demand and revenue opportunities may positively affect earnings and share value.
  • The shift away from Verkor could mitigate potential risks associated with foreign technology partners, further strengthening EnerSys’ control over its supply chain.
  • Investors should monitor progress on construction, funding, and regulatory approvals, as delays or changes could materially affect outcomes.
