Double Black Diamond is the largest U.S. solar project east of the Mississippi River, and the largest solar project in MISO. The scale means that it can provide enough emissions-free energy each year to power more than 100,000 households.
Over the lifespan of Double Black Diamond Solar, Sangamon and Morgan Counties in Illinois are set to receive $100 million in tax revenue. Additionally Swift Current will provide $10 million in community benefits funds to the Sangamon Growth Alliance, Auburn School District, City of Chicago, and Cook County.
“We are proud to be home to one of the largest clean energy projects in the nation. The Double Black Diamond Solar project brings significant economic benefits to our community, contributing $100 million in tax revenue and supporting hundreds of jobs.”
