ROTHSCHILD, Wis. (AP) – A new power plant that burns wood and sawdust is now producing power at Domtar Corp.’s paper mill in north-central Wisconsin. We Energies says the $268 million renewable energy project went into commercial operation on Friday. The biomass plant burns wood, waste wood and sawdust to produce up to 50 megawatts of electricity, while also supplying steam for use by the paper mill in Rothschild. In a statement, We Energies chairman and chief executive Gale Klappa says the addition of the biomass plant enables the Milwaukee-based utility to produce renewable energy on demand – something Klappa says is “simply not available with solar or wind generation.” The Milwaukee Journal Sentinel┬áreports construction of the plant began in June 2011.
