Alliant Energy's Iowa utility has issued a Full Notice to Proceed (FNTP) to KBR for engineering, procurement and construction of a combined-cycle, natural gas-fueled Marshalltown Generating Station (MGS).

Construction has begun in Marshalltown, Iowa, US on the 650MW natural gas-fueled MGS, which is expected to power more than 500,000 homes when commercially operable.

KBR Infrastructure, Government and Power Group president Andy Summers said: "We are thrilled to bring our integrated engineering, procurement, construction, and commissioning skills to bear to successfully deliver a new best-in-class combined cycle generating station to the company's customers."

Located adjacent to Alliant Energy's existing generating site in Marshalltown, the Marshalltown Generating Station will feature two combustion turbines, two heat recovery steam generators, and one steam turbine, which is known as a 2x1 combined-cycle configuration.

Alliant Energy Generation senior vice-president John Larsen said the MGS construction is a key part of the company's long-term energy resource plan that further balances energy supply while reducing emissions.

"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," said Larsen.

"The MGS construction is a key part of the company's long-term energy resource plan."

Expected to power more than 500,000 homes when commercially operable, the 650MW MGS is scheduled start commercial operation in the second quarter of 2017.

Alliant Energy's Iowa utility president Doug Kopp said: "The MGS project has significant economic development and long-term environmental benefits."

In November 2013, Alliant Energy received the project's regulatory approval from the Iowa Utilities Board (IUB), with the condition that necessary pre-construction permits are received.

The company then received an unconditional generating certificate from the IUB in May 2014 upon receiving air permits from the Iowa Department of Natural Resources (IDNR) in April 2014.
