DES MOINES, Iowa (AP) – MidAmerican Energy has announced it has completed the installation of 13 wind turbines near Pomeroy as part of the company’s plan to expand  wind energy production across Iowa. In a news release issued Wednesday, MidAmerican says the turbines are the first of 258 the company is erecting at three wind energy projects in Iowa this year.

The turbines, which are supplied by Siemens Energy Inc., will add more than 590 megawatts to MidAmerican’s energy generation portfolio. That’s enough to power about 190,000 homes. The Pomeroy project is in Pocahontas and Calhoun counties. The remaining turbines will be erected in Cass, Adams, Adair and Marshall counties by the end of the year.
