Catamount Energy Expands Its Wind Energy Portfolio with New Investment.

RUTLAND, Vt. -- Catamount Energy Corp. (Catamount) today announced that its fourth U.S. wind project has been completed and attained full commercial operation on May 24, 2007. Sweetwater 4, located in Nolan County, Texas, is a 240.8-megawatt project using a combination of Siemens and Mitsubishi Wind turbines.

Sweetwater 4 is the fourth phase of the Sweetwater wind project, which totals 504.8 megawatts in operation today. The Sweetwater 4 wind project employs 135 Mitsubishi 1.0-megawatt turbines and 46 Siemens 2.3-megawatt turbines. Its output is being sold to San Antonio's CPS Energy, a municipally owned energy company, under a long-term purchase agreement.

Prior to commercial operation, Catamount Energy and its partner Babcock and Brown co-developed and constructed Sweetwater 4. Under the long-term ownership structure for Sweetwater 4, Catamount and Babcock will remain equity investors and co-managing members of the project. Catamount and Babcock also co-developed and constructed the prior three phases of Sweetwater, with the first phase achieving commercial operation in the summer of 2003. DKRW Energy LLC of Houston was the project originator and continues to co-develop the project. Catamount and Babcock are currently co-funding the development and construction of the 80.5-megawatt Sweetwater 5 project.

"Sweetwater is one of the largest wind energy projects in America, and it will continue to expand," said Catamount President Joe Cofelice. "We are happy to have co-developed and to own, along with our partners, this project that helps to address the need for economically and environmentally sound clean energy."

"Catamount has continued to expand its alternative energy generation business with the recently announced investment in Elemental Power Generation (a fuel cell project developer), our first consent for a wind project in the United Kingdom, and the new investments at Sweetwater," noted Catamount CEO James Moore. "We are pleased to be growing our business rapidly, but our primary focus continues to be on making sound investments and avoiding poor decisions in a sector that is attracting lots of new money and attention," concluded Moore.

Catamount is a developer, owner, and manager of alternative energy projects and has been in the business of providing clean, cost-competitive electricity in the U.S. and Europe for 14 years. More information regarding Catamount is available on its web site at www.catenergy.com.
