Alliant Energy Breaks Ground on Riverside Energy Center Expansion

Alliant Energy on Thursday officially broke ground on a 700-MW combined cycle power plant near Beloit, Wisconsin.

The $700 million expansion of the Riverside Energy Center will be able to produce enough electricity to power 535,000 homes, the utility said. The project also calls for the construction of an integrated, 2-MW solar facility. The project will be built next to an existing gas plant and the 2.3-MW Rock River solar facility.

The expansion, underway on the western edge of a 315-acre campus, will create 1,000 jobs during construction and will pump an estimated $250 million into the local economy, Alliant said in a press release. What’s more, the project will double the Riverside Energy Center’s output.

The new combined cycle plant is expected to begin commercial operation early in 2020. It will replace several older, less efficient coal-fired units destined for decommissioning, the utility said.

“The investment in this site will shape the energy future for our customers and our company,” said John Larsen, president of Alliant Energy-Wisconsin.
