MARSHALLTOWN, Iowa, June 4, 2014 /PRNewswire/ -- Alliant Energy's Iowa utility is ready to move dirt and sink steel.

Alliant Energy's Iowa utility has received all of the necessary regulatory approvals and permits to issue a Full Notice to Proceed (FNTP) for construction of MGS. As a result, construction of the company's approximate 650 megawatt, combined-cycle, natural gas-fueled Marshalltown Generating Station (MGS) is underway. MGS, located in Marshalltown, Iowa, is expected to power more than 500,000 homes when commercially operable.

In addition to issuing the FNTP, the company also announced that KBR has been selected as the project's engineering, procurement and construction contractor. Alliant Energy's Iowa utility expects the MGS to begin commercial operation in the second quarter of 2017.

"KBR is a recognized world leader in the engineering, procurement and construction of large, complex projects," added Larsen. "We are pleased to have KBR on board as a partner in this project as they construct a facility that will provide safe, efficient and reliable energy to our current and future generations of customers."

  • Construction of MGS
