Report Debunks Illinois Coal Claims, Makes The Case For Wind And Solar


A new report is challenging Dynegy-Vistra’s claim that shuttering Illinois coal plants would lead to disastrous power outages.

According to findings from the Natural Resources Defense Council (NRDC) and the Sierra Club, all of Dynegy-Vistra’s coal plants in central and southern Illinois could retire by 2025, and there would still be enough electricity to keep the lights on. Because Dynegy-Vistra’s coal plants are costlier to run than almost any other energy resource, the groups claim, replacing the plants with wind and solar power could help lead to lower electricity costs (relative to 2017) – in turn, saving customers between $12 billion and $14 billion between 2018 and 2030.

Based in Texas, Dynegy-Vistra – a recent merger of Dynegy Inc. and Vistra Energy Corp. – owns eight coal plants in southern and central Illinois. The coal plants analyzed in the report are the Baldwin Energy Station, Coffeen Power Station, Duck Creek Station, E. D. Edwards Generation Plant, Havana Power Station, Hennepin Power Station, Joppa Steam Plant, and Newton Power Station. Together, they have a nameplate capacity of 5,862 MW.

The report, prepared by Vibrant Clean Energy (VCE), analyzed the electricity, customer bill and pollution impacts of closing Dynegy-Vistra’s eight facilities. The report contradicts Dynegy-Vistra’s claim that shuttering its Illinois coal fleet would have negative impacts on the state’s power grid that would lead to power outages and, consequently, require a bailout from the state.

“Illinois doesn’t have to waste money on propping up old coal plants owned by a Texas-based energy company,” states Toba Pearlman, staff attorney and clean energy advocate at NRDC. “There is clearly no need to bail out plants that simply can’t compete against cleaner and cheaper energy resources.”

While the costs to build wind and solar projects are plummeting, the Dynegy-Vistra coal fleet is becoming increasingly inefficient and costly to maintain – due in part to an average plant age of 53 years old, according to the groups. The report notes that it is now cheaper to build a new wind project than it is to keep operating an existing coal plant – a trend seen across the Midwest.

The report explains that replacing the coal plants with “newer, more efficient and cheaper generation reduces electricity production costs and delivers power to customers at lower prices.” The low operating costs of wind and solar result in “electricity production cost-savings that outweigh the initial construction (capital) cost of the renewable capacity and translate into lower electricity prices for Illinoisans over time.”

“Dynegy-Vistra has spent a lot of time and effort promoting a false narrative in which its aging coal-burning power plants are critical to Illinois’s energy future,” says Greg Wannier, staff attorney at the Sierra Club. “This report proves that narrative to be false and outlines one possible vision of a cleaner and more affordable energy future for Illinois.”

The report also shows that phasing out coal would significantly reduce emissions of particulate matter and other harmful pollutants such as nitrogen oxides and sulfur dioxide.
