Washington Group International Inc. (Nasdaq: WGII) announced today it has been awarded a contract by Salt River Project, the largest municipal provider of electricity to the greater Phoenix metropolitan area, to provide architectural, engineering, and procurement support services for a new 400-megawatt, coal-fired generating unit at the Springerville Generating Station in eastern Arizona.

This will be the fourth electric generating unit at the site and will increase the availability of coal-fired power in Arizona and the Southwest.

"Adding a new unit to the Springerville facility will help meet the future growth load of the region while allowing consumers in Arizona to benefit from stabilized power costs and a more diverse power generation source."
