Wisconsin coal-fired plant to install emission-control system

A coal-fired power plant near Wausau, Wisconsin will be the first in the country to use a new emission-control system.

A coal-fired power plant near Wausau, Wisconsin, will be the first in the country to use a new emission-control system. The Journal Sentinel reported the Wisconsin Public Service Corp. received approval from state utility regulators March 20 to install the system at its Weston 3 boiler.

The system, known as regenerative activated coke technology, will cost $275 million to build, the article stated. It will reduce sulfur dioxide emissions by 90 percent and nitrogen oxide emission by as much as 60 percent, the Sentinel reported. The system is less expensive for the utility's customers than other emission controls.

Construction of the new system is expected to begin in 2014 and be completed in 2017, according to the article.

The Weston coal-fired power plant has four electric-generating units, according to Wisconsin Public Service. The fourth unit is the newest, coming online in June 2008. The unit generates 525 megawatts of energy. The utility said the plant is one of the cleanest of its kind in the country.
