MidAmerican Energy is upgrading more than 700 of its wind turbines at three wind farms spread across six Iowa counties. Adam Jacobi (jah-COE-bee), spokesman for the Des Moines-based utility, says work is underway at the company’s Century Wind Farm in north-central Iowa’s Hamilton and Wright counties.
The process involves upgrading the turbines with improved technology and putting longer blades on the existing towers to produce more power.
Jacobi says most of the turbines that are being upgraded were installed in 2004 and ’05, so they’ve been in place well over a decade already. The “repowering” will bring a sizeable boost to the power-generating abilities of each tower.
MidAmerican has entered into agreements with General Electric to complete the upgrades at the three wind farms.
