Danish wind OEM Vestas has received a firm order from Berkshire Hathaway's MidEmerican Energy for 100 of its V110-2.0MW machines as part of the 2GW Wind XI project in Iowa.

The 174MW order includes previously purchased PTC-qualifying components.

"The historic Wind XI project will harness low-cost wind energy for MidAmerican Energy's customers, all while enhancing the reliability and resiliency of the grid," says Chris Brown, president of Vestas' sales and service division in the US and Canada.
