Subaru of Indiana Automotive (SIA), a recognized industry leader in environmental stewardship, has energized a 204-kilowatt rooftop solar project atop its new building expansion in Lafayette, Indiana.
The system went into service in August 2025 and represents the latest step in SIA’s multi-decade effort to reduce its carbon footprint while strengthening Indiana’s clean energy economy.
The solar installation produces more than three times the energy currently consumed by the expansion, meaning the solar installation generates a net surplus of clean power. That surplus is fed back into the company’s operations, creating both long-term energy cost containment and measurable carbon reduction benefits.
The project is expected to offset more than 250 metric tons of carbon dioxide annually, the equivalent of supplying the electricity needs of 43 homes. Over its 30-year operating life, the system will deliver millions of kilowatt-hours of clean electricity, helping Subaru advance its corporate sustainability goals while reducing operating costs of the expansion at its Lafayette facility.
Building on a legacy of environmental leadership
SIA has long been recognized for its leadership in environmental practices. It was the first U.S. auto assembly plant to achieve zero-landfill status and has consistently invested in technologies that reduce waste, conserve natural resources and lower greenhouse gas emissions.
The new solar project builds on that legacy, demonstrating how one of Indiana’s largest manufacturers is using renewable energy as both a cost-containment strategy and a core component of its environmental vision.
Scott Brand, President and Chief Operating Officer of Subaru of Indiana Automotive, said, “The expansion rooftop project completed by Emergent Solar Energy further demonstrates an ongoing commitment to reduce our environmental impact. By expanding the use of renewable energy at our facility, we continue to embrace sustainable technology to help offset our carbon footprint.”
Partnership with Emergent Solar Energy
SIA selected Emergent Solar Energy, a commercial and industrial solar EPC headquartered in the Purdue Research Park of West Lafayette, as its partner for the design and construction of the project. Emergent specializes in turnkey solar and energy storage solutions for large manufacturers and agricultural operations across the state.
