MidAmerican Energy Co. is building a 340 megawatt, $500 million wind farm in Poweshiek County, Iowa, making it the third site in the state selected as part of the utility’s Wind XI project.

The North English wind farm is scheduled for completion in December 2018 and could employ up to 15 people when it enters service. It will include up to 170 Vestas 2.0 MW wind turbines built across 36,000 acres. The turbines will interconnect to the existing Montezuma 345 kilovolt substation.

Construction on other projects in the Wind XI project will start in 2018 and 2019. Altogether, the $3.6 billion initiative will consist of up to 1,000 wind turbines and 2,000 MW of wind generation capacity in Iowa when complete in December 2019.

MidAmerican Energy Company is an energy provider serving 760,000 electric customers and 742,000 natural gas customers in Iowa, Illinois, Nebraska and South Dakota. Tradewind Energy is selling the Iowa-based North English Wind Project to MidAmerican Energy Company.

MidAmerican bought the project from Kansas City-based Tradewind Energy.
