.

The five wind projects, with an anticipated total generating capacity of 2,015MW, are located in New York, Texas, and South Dakota. Under the long-term supply agreement, BP has secured a mix of firm and contingent orders of up to 2,250MW of additional Clipper turbines in its global wind portfolio.

The Clipper/BP Alternative Energy joint development portfolio will be developed over a five-year period. Each project will deploy Clipper’s Liberty wind turbines. The projects will be jointly owned by the two companies with Clipper serving as the project operator in two projects and BP Alternative Energy serving as the project operator in the other three.

As part of the long-term turbine supply agreement, BP Alternative Energy has committed to the purchase of 100MW of Liberty turbines in 2007 and 200MW in 2008 which it will use on other projects in BP’s global wind business. These orders represent the initial firm deliveries under the long-term supply agreement for up to 900 Liberty turbines over the next five years
