Alliant Energy to expand Riverside Energy Center by building combined-cycle natural gas facility

Riverside Energy Center

Alliant Energy’s Wisconsin utility, Wisconsin Power and Light Co. (WPL), announced plans to expand its Riverside Energy Center by building a 650-MW combined cycle, natural gas-fueled facility near Beloit, Wisconsin. The expansion would replace several older generating units in the state that are scheduled to retire in the next few years.

“An investment in new, highly efficient natural gas generation provides significant environmental benefits to Wisconsin, brings hundreds of construction jobs to the state and delivers an economic boost to the region,” said Patricia Kampling, Alliant Energy Chairman, President and CEO.

“Having access to reliable, flexible, around-the-clock power that a combined cycle energy center offers will be a direct benefit to our customers,” said John Larsen, president of WPL. “As part of our long-term planning, the Riverside Energy Center will also be evaluated for the integration of solar energy as we continue to expand our renewables portfolio.”

Alliant Energy expects to file for regulatory approval with the Public Service Commission in early 2015. Upon approval, construction is expected to begin in 2016. The facility is projected to enter operations in early 2019.

The project is estimated to cost approximately $725 to $775 million.
