WBEZ’s Gabriel Spitzer has a piece today on the solar plant under construction in West Pullman, which when completed will be the largest urban solar power plant in the country. When we covered the plant last May, Exelon and SunPower had just announced their plans to build it and seek federal funding. According to the WBEZ story, the two power companies received a $60 million loan guarantee from the federal government, and about one third of the solar panels have already been installed. No word yet on when the plant will go online.
