The turbines will be destined for US wind-energy projects starting construction in 2013 to secure federal production tariff credits.

The scope of the contract includes the supply of its V100-2.0 MW model turbines for each project as well as Active Output Management (AOM) 4000 maintenance program which guarantees turbine availability.

The program maximizes uptime and performance and covers periods up to 10 years, suitable for customers who want the traditional time-based availability guarantee of up to 97%.

RES Americas president and CEO Susan Reilly said that the company has awarded 60MW wind turbine order to Vestas as part of its agreements for up to 610MW.

"This is a great example of how the ‘start-of-construction’ language in the current production tax credit for wind energy is generating increased spending and creating U.S. manufacturing jobs," Reilly added.
