We Energies said Nov. 11 that the biomass-fueled power plant on the site of Domtar Corp.’s Rothschild, Wisc., paper mill was placed into commercial operation on Nov. 8, after testing and commissioning activities were successfully completed.
Wood, waste wood and sawdust are being used to produce up to 50 MW. The steam provided by the plant is also 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.”
The company’s renewable energy portfolio includes the state’s two largest wind developments – the 145-MW Blue Sky Green Field Wind Energy Center in Fond du Lac County and the 162-MW Glacier Hills Wind Park in Columbia County. In total, these three renewable energy projects are capable of delivering nearly 360 MW of renewable energy, enough to supply about 120,000 homes.
More than 400 workers contributed to the construction of the biomass plant, which also will support about 150 permanent jobs in the region, including independent wood suppliers and haulers from northern and central Wisconsin who will secure needed waste wood. It is officially called the Rothschild Biomass Cogeneration Facility.
Under Wisconsin law, utilities statewide must use renewable energy to meet 10% of the electricity needs of retail customers by the year 2015. With the commercial operation of the Rothschild biomass plant, We Energies estimates that it has secured enough renewable energy to remain in compliance with the state mandate through 2022.
Domtar’s use of the steam produced by the plant will also help improve the paper mill’s energy efficiency and reduce overall emissions at the site by more than 30%.
We Energies serves more than 1.1 million electric customers in Wisconsin and Michigan’s Upper Peninsula and 1.1 million natural gas customers in Wisconsin.
