Officials with the Rolling Hills wind project say the project is still scheduled to wrap up by the end of the year.

On Wednesday, representatives with MidAmerican Energy, Mortensen Construction, and Siemens Energy held a press conference to showcase the project.

A wind turbine was displayed at the conference which allowed attendees to see the turbine up close. They were allowed to sign the blade to commemorate the day’s celebration. The blade is about half the length of a football field and weighs 12 tons.

Rolling Hills is one of three MidAmerican Energy Companies that are taking place this year. The other projects are in Calhoun, Marshall, and Pocahontas counties.

Jerry Grundtner, The Vice President of Project Development for Mortenson Construction, says the foundations are about fifty percent complete, and the turbines are about twenty percent complete.

When the project is complete, the 258 wind turbine expansion project will add 593.4 megawatts of renewable energy. MidAmerican says that is enough power for about 190,000 homes.
