MidAmerican Energy has made a firm order for 153MW worth of Vestas V110-2.0 wind turbines as part of the 2GW Wind XI order by the subsidiary of Warren Buffet’s Berkshire Hathaway.

The turbines will be manufactured at Vestas’ Colorado factories with expected delivery in 2017. The order includes a five-year service agreement.

"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 US and Canada.
