Airtricity Finalizes Largest Wind Project to Date.

$300,000,000 Facility Will Provide Power to TXU 

SWEETWATER, Texas -- Airtricity, Inc., a leading renewable energy company, announced the construction of its largest wind farm to date. The 209 megawatt Roscoe Wind Farm will provide power to TXU Wholesale, a subsidiary of TXU Corp., under a five-year sales contract. The project area stretches into three counties and will cover nearly 30,000 acres when it is completed.

The Roscoe Wind Farm, which is scheduled for completion by the end of the year, will annually produce enough energy to power 60,000 homes and save approximately 375,000 tons per year in greenhouse gas emissions, The project will help Texas meet its renewable energy goal of 5,000 new megawatts of its power from renewable sources by 2015. In 2006, Texas became the nation's leader in installed wind capacity.

"Airtricity is playing a leading role in helping Texas and America meet its fast-growing energy needs," said Airtricity North America CEO Declan Flanagan. "As electricity demand and natural gas prices continue to rise policymakers and businesses like TXU are seeing the benefit of tapping into Texas's vast wind energy resource."

Airtricity's third Texas project, the Roscoe Wind Farm is located on a site adjacent to the town of Roscoe, 45 miles southwest of Abilene in an area primarily used for cotton farming. The site will employ 209 1.0 megawatt Mitsubishi 1000A turbines.

Airtricity's fourth Texas wind farm, the 126 megawatt Champion project, recently commenced construction five miles from the Roscoe site. By the end of this year Airtricity will operate 550 megawatts of wind power in Texas, making it one of the leading providers of clean, native energy in the state. The company is also currently constructing a project in western New York.

"We're proud of our position as the No. 1 purchaser of wind power in the state of Texas, and this contract only solidifies that," said Mike McCall, chairman and CEO of TXU Wholesale. "We are well on our way to more than doubling our wind power purchases to 1,500 MW and increasing our investments in alternative energy, as announced as part of our merger agreement with Texas Energy Future Holdings Limited Partnership."

Texas is leading the world in harnessing clean, native wind energy and 2007 is set to be a record year with over 1,000 megawatts being installed. In addition to adding much needed tax revenues to school districts, the Texas wind industry is creating employment and opportunity in a range of disciplines, including construction, operations and maintenance. At its peak, more than 500 people will be employed in the construction of the Roscoe and Champion sites. Airtricity is renovating vacant commercial space in the town of Roscoe to act as its regional operations center. When complete the operations center will employ more than 20 workers.
