Alliant says baghouse and scrubber now ready at Edgewater 5

Alliant (NYSE:LNT) utility Wisconsin Power and Light (WPL) said recently that it has completed construction of a new $250m baghouse and scrubber project at Unit 5 of the Edgewater power plant in Sheboygan, Wisconsin.

Unit 5 is a roughly 400-MW coal unit. The other operating unit at the plant is Edgewater 3, which is roughly 300 MW. The Edgewater plant had a capacity factor of more than 61% in 2014, according to GenerationHub data.

The environmental technology should reduce sulfur dioxide (SO2) by approximately 90%, Alliant said in a June 22 news release. The company held a ribbon-cutting ceremony that included employees, project contractors, labor leaders, and state and local officials.

The project employed up to nearly 300 workers during installation. The baghouse and scrubber system is the second major air quality improvement project built at Edgewater Unit 5. In 2012, the company installed a selective catalytic reduction (SCR) system to reduce nitrogen oxide (NOx).

Alliant is also retiring older and less efficient facilities, building the natural gas-fueled Riverside Expansion near Beloit, Wisconsin and additional renewable energy and continued investments in energy efficiency.

“This air quality improvement project furthers our transition to providing cleaner and more efficient energy to our customers,” said John Larsen, President of Alliant Energy’s Wisconsin utility. “We are working to ensure that Wisconsin has the energy it needs to grow while minimizing our impact on the environment. The strong partnership we had with labor, our contractors and the community was impressive and made this a quality and environmentally responsible project,” Larsen said.
