Metso Corporation’s press release on September 14, 2011 at 01:00 p.m. local time

Metso will supply a biomass boiler to the We Energies/Domtar Biomass Energy Project owned by We Energies. The biomass boiler is a key component of a major investment to build a new biomass-fueled cogeneration power plant which will be located at the Domtar Mill in Rothschild, Wisconsin, USA. The value of the order will not be disclosed.

The biomass boiler plant will utilize circulating fluidized bed (CFB) technology and will use waste wood from logging and mill activity, tree trimming and sawdust as the main fuel. The plant will produce approximately 50 megawatts of renewable electric power and provide process steam to the mill.

“We chose Metso for our biomass project based on their proven biomass experience and robust boiler design features, coupled with their strong organizational commitment to sustainable technologies. ”We fully expect to realize the project goals of cogenerating cost-effective renewable electric power and process steam , while reducing overall emissions at the Domtar Rothschild mill”, says Al Mihm, project director at We Energies.

“Metso is proud to be chosen by We Energies for such an industry-leading collaboration. This order continues to reinforce Metso’s commitment to be the pre-eminent supplier of bioenergy plants”, says Robert Deneault, General Manager Capital Sales at Metso’s Power business line in North America. ”Once built, this boiler will join a fleet of 33 Metso CFB boilers already operating in the US, and this one will be the largest and most efficient biomass-fired boiler of them all”, adds Dave King, President at Metso’s Power business line in North America.

The commercial operation of the plant is scheduled for 2013. The value of the order is included in the Energy and Environmental Technology’s second quarter 2011 orders received.
