The turbines will be manufactured at Vestas’ Colorado factories with expected delivery in 2017. The order includes supply and commissioning of the wind turbines as well as a five-year Active Output Management 5000 (AOM5000) service agreement: Vestas’ full-scope service package maximizing uptime and energy production.

“By employing wind energy, the Wind XI project will bring clean, domestic, low-cost energy to MidAmerican customers as well as hundreds of millions of dollars in economic benefits to Iowa communities and long-term American jobs through the manufacturing, construction, and operations of Wind XI”, said Chris Brown, President of Vestas’ sales and service division in the United States and Canada.

Wind XI follows MidAmerican’s first of its kind utility commitment to providing customers with 100 percent renewable energy generation.

MidAmerican Energy Company, a subsidiary of Berkshire Hathaway Energy, is the largest regulated utility owner of wind energy in the United States. With the investment in Wind XI, the utility will generate 85 percent of its retail load from wind.

Potential future order intake under the 2,000 MW Wind XI project is expected to occur as partial deliveries under the master agreement and will be announced firm and unconditional consistent with Vestas’ order announcement policy.
