Mammoth Solar
Mammoth Solar is a 1,600–megawatt (MWDC) solar photovoltaic power project in Pulaski and Starke Counties, Indiana, United States. The plant is being constructed in three phases and will be the largest photovoltaic power station in the United States and western hemisphere when complete. The first section of 480 MW came online in July 2024. The project is being developed by Doral Renewables, a subsidiary of Israeli company Doral Energy, and is expected to cost US$1.5 billion. It will produce enough electricity to power 250,000 homes.
Doral Energy has contracts with about 60 landowners to use approximately 13,000 acres (53 km2) of land for the project, though excluding setbacks, forests, and wetlands, the 2.85 million solar panels will cover only about 2,500 acres (10 km2). Most of the farmland is used for corn ethanol production; powering gasoline cars with bioethanol consumes around 70 times more land than powering electric vehicles with solar power. Doral is working with landowners to support dual uses of the project land as agrivoltaics to allow for grazing of 2,000 sheep, alpacas and donkeys and farming of various crops around the solar panels, including research on plant growth under panels. Operations will be managed by NovaSource.
The phases will use three points of interconnection on a 345 kV power line to deliver power into the PJM Interconnection. American Electric Power has power purchase agreements for electricity produced in phases one and two and half of phase three. Constellation Energy has a power purchase agreements on the other half of the power in phase three, passed on to four corporations.
Pulaski and Starke Counties will each see US$1 to 2 million per year in additional property tax revenue for the life of the project, about a fifth of their budgets. The project is also making economic development payments to Pulaski County totaling $375,200 in 2024. Pulaski County also designated the project an Economic Revitalization Area, granting it a tax abatement; the Indiana Court of Appeals rejected a lawsuit challenging the designation. Local landowners are paid about US$600–1,000 per acre leased.
The project's name references mastodon fossils that were unearthed in the region of the solar project, now on display at the National Museum of Natural History.
NIMBY groups have organized against the project and filed suit against Pulaski County's zoning approval.
Doral is considering additional phases of the project, with up to 900 MW called Mammoth Grazing Lands and Pastures.
SOLV Energy is the project's EPC contractor.
