The wind farm, developed by Emerging Energies of Wisconsin, project is estimated to generate nearly 64 GWh of electricity annually.

The N100s are the latest generation in the Nordex family of 2.5 MW N80/N90 wind turbines. Designed specifically for low to moderate wind speeds, the N100s are said to be ideal for numerous sites across the USA.

The N100 wind turbines have a hub height and rotor diameter of 100 m, with a rotor sweep of 7823 m2. This translates into an increase in power yield by up to 20% at average wind speeds of around 7.5 m/sec, compared to the N90 wind turbine, Nordex USA says.

For the project, called the Shirley Wind Farm, Nordex will supply cold climate models of the N100 wind turbines, upgraded to operate in temperatures as low as -20°F (~ -29°C).

Nordex will deliver and install the wind turbines in the third quarter of 2010, with project completion slated for the fourth quarter. The order also includes maintenance and technical operation under a 10-year service contract. The project carries a 20-year power purchase agreement contract with Wisconsin Public Service Corporation.

Nordex USA is currently building a manufacturing plant in Jonesboro, Arkansas, which will produce N90/N100 wind turbines for the US market beginning in September 2010.
