Tetra Tech, a provider of consulting, engineering and technical services, has bagged three wind energy projects valued at more than $69 million.

The company has been awarded two engineering, procurement, and construction (EPC) projects and one balance of plant (BOP) construction project for wind farms.

In aggregate, these wind farms will generate 218.2 MW of clean energy—enough to power more than 55,000 homes.

Details are as follows:

·          For Oklahoma Gas & Electric Company, Tetra Tech will provide EPC services for the OU Spirit Wind Farm, which shall consist of 44 Siemens 2.3-MW turbines near Woodward, Oklahoma.

·          Tetra Tech was also awarded a project to provide BOP services for the High Sheldon Wind Farm in Wyoming County, New York. This Invenergy LLC project will have a maximum electrical generating capacity of 112.5 MW. Tetra Tech is constructing roads and foundations to support the installation of 75 wind turbines on predominantly active agricultural lands.

·          Finally, Tetra Tech will provide EPC services for Kodiak Electric Association's Pillar Mountain Wind Project on Kodiak Island, Alaska. This project includes the installation of three General Electric turbines capable of generating 4.5 MW of power. Work on the project began in late May and is expected to be complete by July 2009.
