The next 90.8MW phase of MidAmerican Energy Company's $3.6bn Wind XI project in the US state of Iowa will utilize Siemens Gamesa Renewable Energy turbines, the utility said.

A MidAmerican spokeswoman told Recharge that 30 of the 35 turbines to be utilized in the 90.8MW Ivester wind farm in west-central Grundy County will come from an order that was awarded to SGRE in April.
