OPPOSITION: Sierra Club, Clean Wisconsin
BACKGROUND: In 2007 the developer proposed a 300 megawatt, $800 million coal and biomass unit at the Nelson Dewey facility in Cassville, Wisconsin. Sierra Club and others opposed the plant due to CO2 and mercury emissions and potential rate increases needed to pay for its construction. Some conservation groups favored the expansion. Initial cost estimates proved to be excessively low and by September 2008 the estimated development cost exceded $1.3 billion. In November the Wisconsin Public Service Commission unanimously rejected the proposal on the grounds that the project was too costly when compared to other alternatives, including natural gas, and too risky given litigation and regulatory uncertainty associated with coal plants.
