The wind farm consists of four sections and covers an area of 400 km², twice the size of a city like Düsseldorf, in Germany.

The wind turbines were manufactured by Mitsubishi, General Electric and Siemens.

Frank Mastiaux, CEO of E.ON Climate & Renewables, says: “With large-scale projects like Roscoe we are helping renewables to achieve a faster breakthrough in economic and technological terms. For this purpose we will invest €8 billion worldwide up to 2011. Our aim is to reach a capacity of 10,000 MW in 2015. North America is one of the most attractive markets for renewables worldwide, especially for onshore wind plants.”
