Mammoth Central Solar
Mammoth Central Solar is the third and final phase of the Mammoth Solar project, one of the largest solar projects in the US. Mammoth Central, also the largest phase of the project, is estimated to generate 600 MW of energy. Because of its size, the Mammoth Central project will be constructed in 2 phases, Mammoth Central 1 and Mammoth Central 2. This project is expected to generate enough clean energy for approximately 135,000 households.

About Mammoth Central Solar
Mammoth Central is currently under construction in Pulaski County, Indiana. Both of its phases, together with the Mammoth South project, all constructed simultaneously, is employing approximately 1,200 workers, 93% of which are Hoosiers. Doral Renewables has secured a power purchase agreement for all 600 MW of the Mammoth Central project. 300 MW of the electricity produced by the Mammoth Central 1 phase would be sold to Bank of America, PNC Bank, CVS Health and Dietz and Watson, all via Constellation. The additional 300 MW would be sold to AEP Energy.

Project History
The project has achieved financial closing and begun substantial construction in May 2025. It is expected to become operational during 2027. Mammoth Central is expected to have a significant agrivoltaics practices incorporated in it, including livestock grazing serving as vegetation management, pollinator habitats for various species and crop production. These practices would be led by local farmers, allowing them to return to heritage farming practices, continue farm operations, maximize land use and diversify and expend their revenue stream.
Project Outcome
The Mammoth Solar project in its entirety is expected to generate 1.3 GW of energy, that will power approximately 275,000 households annually and is located across Starke and Pulaski counties in Northwest Indiana. The project was named “Mammoth” because of ancient mammoth bones discovered in fields where it would be built and because of the growing size and scope of the mammoth project. The Mammoth Solar project started in 2019 as grassroots effort in the homes and barns of local farmers. Today, Mammoth Solar has over 65 families, who lease their land to Doral Renewables as part of this project. Upon the decommissioning of the project, the landowners receive their land back and can utilize it as they see fit.
