Berkshire Hathaway Energy subsidiary MidAmerican Energy Company has placed an order to Vestas for the delivery of V110-2.0MW turbines for the 2,000MW Wind XI project in Iowa, US.

To be built at Vestas’ four factories in Colorado, the turbines  are expected to be delivered in Q2 2018.

Scheduled to be fully operational by 2020, the Wind XI project will enable MidAmerican Energy to produce an estimated 95% of its annual retail load from wind.

“The current order includes supply and commissioning of the turbines in addition to a multi-year Active Output Management 5000 (AOM5000) service agreement.”

The project comprises multiple sites in Iowa that will enter service between 2018 and 2019.

Vestas’ US and Canada sales and service division president Chris Brown said: “We are pleased to continue working with MidAmerican Energy on this next phase of the Wind XI project.

“The production, construction, and operations of the turbines for Wind XI will generate significant economic benefits for landowners, their community, and the supply chain that supports these American-made turbines.”

The current order includes supply and commissioning of the turbines in addition to a multi-year Active Output Management 5000 (AOM5000) service agreement.
