The Lakeside power station was built in the 1930s on the edge of Lake Springfield by the City Water, Light and Power (CWLP) department of Springfield, Illinois. In the mid-1960s, there were seven coal-fired turbine-generators built. When the plant was retired in May 2009, only Units 6 and 7 were still in operation; both units had a 38 megawatt (MW) capacity. After prolonged use and stronger environmental regulations, CLWP decided to decommission the plant instead of investing into upgrading the existing units. CLWP built and began operating the new Dallman 4 Power Station, another coal-fired plant, to continue supplying the city with electricity in 2009.[1]

Pollution Concerns

In 2018, a report put together by various environmental groups, including the Environmental Integrity Project, Earthjustice, Prairie Rivers Network and the Sierra Club, showed toxic pollutants emanating from 22 of the 24 coal ash dump sites used by the Lakeside station, as well as other CWLP power plants. The groups found unsafe levels of boron, sulfate, and arsenic in the sites investigated. They also noted that CWLP's ash ponds were all unlined, resulting in potential groundwater contamination that could penetrate the city's nearby drinking water source.[2]
