Danish wind turbine manufacturer Vestas Wind Systems A/S (VWS.KO) said Thursday it has received an unconditional order for 55 v100-1.8 megawatt wind turbines for a U.S. wind farm project.

The order, which comprises a total of 99 megawatts in production capacity, an Active Output Management 4000 maintenance program and a five-year service and maintenance agreement, has been placed by E.On Climate and Renewables North America, a U.S.-based unit of German energy group E.On AG (EON.XE).

The turbines will be erected at the Anacacho wind-energy project in Texas, Vestas said. The contract is a supply-only contract, and delivery is scheduled for mid-2012, commissioning for late 2012.
