This project is designed to reduce mercury emissions through an activated carbon injection system and baghouse to comply with Wisconsin’s mercury rule.
The project will also reduce sulfur dioxide (SO2) emissions through the installation of dry flue gas desulfurization systems.
This equipment will provide flexibility in complying with state and federal SO2 emissions requirements such as the Clean Air Interstate Rule, the EPA’s proposed Clean Air Transport Rule and the Clean Air Visibility Rule.
WPL, a subsidiary of Alliant Energy, along with co-owners Wisconsin Public Service and Madison Gas and Electric, received approval from PSCW.
WPL’s share of the entire project is expected to be $290m.
