Bechtel, a global leader in engineering and construction, has officially entered the full construction phase of the Mammoth Solar facility in Indiana. This landmark project, in partnership with Doral Renewables, represents a major leap forward for clean energy in the U.S., set to power around 200,000 Midwest homes once complete.
Bechtel received Full Notice to Proceed (FNTP) from Doral Renewables, enabling the company to start permanent construction activities on three major phases: Mammoth South, Mammoth Central I, and Mammoth Central II. Combined, these phases will deliver 900 megawatts of solar energy as part of the 1.3 gigawattAC Mammoth Solar facility—one of the largest of its kind in the United States.
A Boost for U.S. Solar Capacity and Local Economy
This initiative is expected to increase Indiana’s solar capacity by more than 20%, further cementing the state’s commitment to clean energy. It’s not just an energy project—it’s a jobs engine. Bechtel estimates that the project will create over 1,200 construction jobs, including at least 15% allocated to apprenticeships, helping young professionals gain hands-on industry experience.
“Bechtel is proud to partner with Doral to deliver one of the nation’s largest solar projects,” said Scott Austin, Bechtel’s General Manager of Renewables & Clean Power. “We’re working closely with local trades, creating high-quality jobs, and helping ensure a cleaner energy future.”
Smart Construction with Sustainability in Focus
Bechtel is leading the engineering, procurement, construction, commissioning, and overall project management of Mammoth Solar. The company is also applying digital delivery tools and autonomous technology to speed up construction and boost safety and quality.
Notably, the site will feature agrivoltaics—a dual-use strategy that combines solar power generation with agriculture. Local farmers will be able to graze livestock and grow crops around the solar panels, maximizing land use while supporting the local economy.
A Sustainable Partnership
Doral Renewables, the project’s owner and developer, is known for its 18 GW clean energy pipeline across the U.S. The company emphasizes community engagement, environmental stewardship, and innovative solutions like agrivoltaics in all its projects.
“Thanks to careful planning and teamwork, we are now entering the construction phase with confidence,” said Amit Nadkarni, SVP at Doral Renewables. “This project reflects our values—clean energy, community support, and long-term sustainability.”
Looking Ahead On Mammoth Solar project
By 2027, the Mammoth Solar project will not only contribute significantly to America’s clean energy goals but also set a precedent for community-first renewable energy development. With 1 million solar panels made in the U.S., it’s a true symbol of innovation, sustainability, and economic opportunity.
