Houston and Austin, Texas, December 15, 2005 – Horizon Wind Energy LLC (Horizon) and RES America Developments, Inc. (RES) have agreed to build the first 200 MW phase of the Cross Timbers Wind Farm in Shackelford County, Texas. Cross Timbers Wind Farm has been developed by RES over the last several years. Under the provisions of the sale, RES will complete engineering of the project and will construct the wind farm in 2006, while Horizon will own and operate the project. The transaction is expected to close by the middle of January 2006.

The project is located approximately fifteen miles northeast of Abilene, Texas. The first phase, known as
“Mesquite” is expected to provide enough power to supply approximately 63,000 homes. The sale provisions provide an option for Horizon and RES to build a second 200 MW phase, and an anticipated third 200 MW phase could bring the Cross Timbers project total to 600 MW.

“We look forward to working with RES to complete the development and construction of Cross Timbers,”,

said Horizon’s CEO, Alec Dreyer.

"We are impressed with their development work to date and are confident that their construction expertise will ensure that the first phase of the project will readily meet its online date of January 2007. Mesquite’s excellent wind resource and transmission delivery point make it a very attractive project in the ERCOT market and we are pleased to add it to our portfolio. While we are new to Shackelford County, we will work hard to be good neighbors, and are pleased that our project will contribute to the economic development of the area."

Craig Mataczynski, President and COO of RES, said,

"We are delighted to start construction of the Cross Timbers project. It is a reflection of the positive relationship we have developed with Horizon and RES’s success in the North American market. Horizon’s capabilities make it an ideal owner and operator of the project. Its extensive experience in the wind industry, coupled with its strong financial backing, will provide the support the project needs to reach its potential to be a major contributor to the Texas wind power market.”

The project will use one hundred 2MW wind turbines. Interconnection, road and design work is already well underway for the first two phases of the project.

In October this year, Horizon and RES entered into an agreement to construct the 229MW Wild Horse wind power project near Ellensburg, Washington State. Wild Horse was developed by Horizon and will be owned by Puget Sound Energy. RES has been contracted by Horizon to construct the site infrastructure consisting of roadways, turbine foundations and the electrical collection system. Major construction began in October of this year.
