What was a brown, unproductive and contaminated field on Chicago's South Side a year ago is now home to more than 32,000 solar panels able to generate power for hundreds of homes each year.
"The project is a great example of the great things that when the government, private sector, non profit sector comes together. Things can change," said Chicago Mayor Richard Daley.
Exelon Corp. signed a 25-year lease with the city and built the installation for $60 million.
Nationwide, there are more than 22,000 megawatts of large-scale solar projects under development, or enough to power 4.4 million homes, the Chicago Tribune reported.
Illinois has laws that aim to double the state's solar power supply and create thousands of "green" jobs. Exelon hopes to learn from the West Pullman plant on how to better construct and operate more facilities like it in the future.
