Once all four phases are completed in mid-2009, the Roscoe wind farm will have 627 wind turbines and a total capacity of 781.5MW, enough to power 265,000 Texan homes.

The Roscoe wind farm is one of six that E.ON Climate & Renewables operates in the US, five of which are in Texas. The company has plans to expand its renewable capacity around the world at an increasing pace over the next few years.

Frank Mastiaux, CEO of E.ON Climate & Renewables, said: We have managed to grow our worldwide wind power capacity fourfold to 1,800MW in the last 15 months. Just under half of that capacity is in the US. This growth and the development of the Roscoe wind farm in particular, underscore our interest in long-term investments and high-quality renewable projects in the US.
