Natural gas and solar-powered Riverside Energy Center expansion seeks state approval

Alliant Energy’s (NYSE:LNT) Wisconsin utility is seeking approval from the Public Service Commission of Wisconsin (PSCW) to construct a combined-cycle, natural gas-fueled generating station at the company’s Riverside Energy Center near Beloit, Wis.

“We’re pleased with the support we’ve received from customers, community organizations and government officials since we announced the project last fall,” said John Larsen, President of Alliant Energy’s Wisconsin utility. “By replacing about 700 megawatts of aging generation with a highly efficient natural-gas facility, this project will play a large role in the modernization of our Wisconsin fleet and reflects our continued commitment to environmentally responsible resources.”

The proposed project location is on the site of Alliant Energy’s existing Riverside Energy Center, Beloit Operations Center and Rock River Generating Station. The company has had facilities in the Town of Beloit for over 50 years and has produced power in the region since the 1920s.

The expansion will include advanced technology to enhance performance and, as part of Alliant Energy’s plan to expand its renewable energy portfolio, the facility’s operations will be powered in part by a solar-energy installation.

“Integrating solar and natural-gas generation is a new technology application for us, and we are eager to use it as a research and learning tool, collaborating with local schools, colleges, the Electric Power Research Institute and industry partners,” said Larsen. “The solar component will give us a chance to refine our understanding of utility-scale renewables.”

The PSCW’s evaluation process will include extensive analysis and public input. If approved, the company expects to begin construction in the summer of 2016 and complete the approximately 650-megawatt facility in early 2019. The estimated project investment is $750 million, excluding transmission and AFUDC. The Riverside Energy Center expansion is capable of powering more than 500,000 homes, while creating hundreds of family-supporting jobs during its construction and additional long-term operational positions upon completion.

The project’s application for a certificate of public convenience and necessity (CPCN) can be found at under docket no. 6680-CE-176. More details regarding the proposed facility are also available at
