The Iowa Utilities Board has approved a plan from the state's largest utility company to install hundreds of wind turbines by the end of 2015.
Gov. Terry Branstad said Monday that the board had approved the $1.9 billion project from the MidAmerican Energy Company.
Branstad says construction will begin in September and the turbines will be located in five Iowa counties — Grundy, Madison, Marshall, O'Brien and Webster. When the company announced the expansion in May, they did not announce locations.
Customers won't see new rate increases because federal tax credits are expected to offset the project's cost over the next 30 years.
MidAmerican is Iowa's largest energy company, bringing electricity to 734,000 customers and natural gas to 714,000 customers in Iowa, Illinois, Nebraska and South Dakota.
