A new 9.1-MW solar array will help residents of Waukegan, Illinois, reduce energy bills. State incentives for low-income solar made the project possible.

Residents who subscribe to get energy from the solar farm are guaranteed to see savings on their energy bills, under a state program incentivizing solar in low-income areas. The 9.1-megawatt Yeoman Solar Project, which went online last month, can provide energy for about 1,000 households, as well as the Waukegan school district, which owns the land.

The school district bought the site in the 1950s hoping to build a new high school. But the land proved too swampy, and from 1958 to 1969 it was used as a dump for industrial and municipal waste. The highly contaminated Yeoman Creek Landfill was finally cleaned up 20 years ago, and now the district receives lease payments from CleanCapital, the national solar-investment company that owns and operates the solar farm. Such brownfields are attractive locations for solar installations.
