Wisconsin cogeneration plant now operational

By Staff | December 30, 2013

WE Energies placed its 50-MW biomass cogeneration plant in Rothschild, Wis., into service in November. The plant, which has been under development the past four years, is located on the site of Domtar Corp.’s century-old paper mill. 

The plant will take in approximately 500,000 tons per year of biomass feedstock, including wood, waste wood and sawdust. The feedstock will come ready-to-burn from Domtar’s fuel yard or will be shredded or chipped offsite by suppliers. 

Steam produced at the facility is supplied to the paper mill, supporting Domtar’s sustainable papermaking operations. 

"The addition of the biomass plant enables us to produce renewable energy on demand," said Gale Klappa, WE Energies chairman, president and CEO. "That benefit is simply not available with solar or wind generation."

Vendors for the project include Metso, which supplied the circulating fluidize bed boiler, and General Electric, which supplied the steam and turbine generator. Appleton, Wis.-based Boldt Construction was the project manager.
