PacifiCorp has awarded a multi-year engineering, procurement and construction (EPC) contract to EC Source, a MasTec Inc. affiliate, to build its Sigurd-to-Red Butte transmission line, a key section of PacifiCorp's Energy Gateway transmission expansion program.

Located in south central Utah, the Sigurd-to-Red Butte segment will be approximately 169 miles long and consist of a new single-circuit 345 kV transmission line from the Sigurd substation in Sevier County to the Red Butte substation in Washington County.

Project construction is scheduled to begin in 2013. When completed in 2015, the new line will deliver additional power to serve customers of PacifiCorp's retail operations, Rocky Mountain Power and Pacific Power. Together, these companies serve more than 1.7 million customers in six Western states.

The Sigurd-to-Red Butte project represents the second Energy Gateway segment EC Source has been contracted to build; the company is currently completing construction of PacifiCorp's 100-mile-long Mona-to-Oquirrh line, which is also in Utah.

"This segment, and our overall Energy Gateway transmission investment, is a fundamental part of PacifiCorp's plans to ensure long-term supply of reliable and affordable energy to meet the growing needs of our existing and future customers," says Natalie Hocken, PacifiCorp senior vice president of transmission and system operations.
