Proposed Marshalltown Coal-Fired Power Plant

Iowa Office of Consumer Advocate
Completed April 2008

Synapse evaluated the economics of the proposed coal plant in Iowa. Synapse found that Alliant Energy had not prudently considered the potential for further increases in the cost of building the plant or the costs of likely federal regulation of greenhouse gas emissions. Synapse also found that a portfolio of energy efficiency, wind resources, and natural gas capacity was a lower cost option.
