Valley Power Plant conversion

We filed applications on April 26, 2013, with the Public Service Commission of Wisconsin for approval to convert the plant’s fuel source to natural gas and upgrade the natural gas infrastructure near the 280-megawatt facility in Milwaukee.

West Central natural gas lateral

Western Wisconsin needs additional natural gas supply to ensure reliability in the future and to meet growing customer demand. We are evaluating areas for potential natural gas distribution routes to serve the communities between Eau Claire County and the city of Tomah in Monroe County.

Pipeline replacement

As part of our ongoing system improvements, we are replacing aging natural gas lines with new pipe that is more resistant to corrosion and earth movement.

Completed projects

Oak Creek Power Plant air quality control

The air quality control project at Oak Creek Power Plant significantly upgraded existing environmental controls on the older units at the plant to further reduce SO₂ and NOx emissions in 2012.

Oak Creek Power Plant expansion

Oak Creek Power Plant expansion included construction of two, 615-megawatt coal-fueled generating units in 2010 (Unit 1) and 2011 (Unit 2). The emission-control technology makes the Oak Creek expansion units the cleanest coal-fueled units in the United States.

Pleasant Prairie Power Plant carbon capture demonstration

In 2009, Pleasant Prairie Power Plant demonstrated a chilled ammonia scrubber technology to capture 90 percent of carbon dioxide emissions from a portion of flue gas from one of the plant’s boilers. This was a first step in developing a commercial-scale technology to capture CO2 from existing coal-fueled power plants. Phase two of the research is taking place at an American Electric Power plant in West Virginia.

Blue Sky Green Field Wind Energy Center

In May 2008, Blue Sky Green Field Wind Energy Center began operating 88 wind turbines in the towns of Marshfield and Calumet in northeast Fond du Lac County. The site is designed to generate 145 megawatts of electricity and is capable of powering more than 36,000 residential homes.

Port Washington Generating Station

Port Washington Generating Station consists of two, 545-megawatt high-efficiency natural gas-fired units, which went into operation in 2005 and 2008.

Pleasant Prairie Power Plant air quality control

As part of our commitment to upgrade environmental performance, we completed a new air quality control system in 2007. A selective catalytic reduction system was put in place to reduce emissions of NOx, and a flue gas desulfurization system was constructed to reduce SO₂.

Presque Isle Power Plant mercury removal

A mercury removal demonstration project was installed at the Presque Isle plant in 2006. It reduced mercury emissions by 70 to 90 percent using the Electric Power Research Institute’s TOXECON process. The process uses a fabric filter in conjunction with sorbent injection to remove mercury and other emissions downstream of the plant’s existing particulate control device. This mercury removal project is one of the largest of its type currently treating flue gas from Western sub-bituminous coal-fired units of at least 270 megawatts.
