PacifiCorp has awarded a multi-year engineer, procure and construct contract to build its Sigurd to Red Butte transmission line in south central Utah, a key section of PacifiCorp’s Energy Gateway transmission investment to meet the current and projected needs of its electric customers.

The contract has been awarded to EC Source, a MasTec, Inc. affiliate. EC Source will provide engineering, procurement and construction services for this major transmission project. It is the second Energy Gateway segment EC Source has been awarded; the company is currently completing construction of PacifiCorp’s 100-mi Mona to Oquirrh line also in Utah.

Sigurd to Red Butte construction is scheduled to begin in 2013. When completed in 2015, it 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.

“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,” said Natalie Hocken, PacifiCorp senior vice president, transmission and system operations.

The Sigurd to Red Butte segment is approximately 169 mi in length consisting of a new single circuit 345-kV transmission line from the Sigurd substation in Sevier County to the Red Butte substation in Washington County.

“We’re pleased to begin construction of this important addition to the transmission system we all depend on,” said Richard Walje, Rocky Mountain Power president. “We look forward to completing it on time and within budget to provide the safe, reliable electric service that is essential to the economies of all the states we serve. We appreciate the efforts of federal agencies and county and city officials in working through the many extensive details of this project.”

During construction, EC Source will have multiple project facilities along the transmission line route in Utah and will utilize the local Utah labor force. Engineering and procurement activities are expected to begin in December 2012 with construction starting in April 2013 and the line placed in service summer 2015.

“We are proud of the successful Mona to Oquirrh transmission line project for PacifiCorp which is now nearing completion. On the new Sigurd to Red Butte segment, safety, environmental stewardship, technical excellence and providing industry leading labor and equipment resources again will be our primary objectives,” said Jose Mas, MasTec’s chief executive officer, MasTec “The award of this second contract will allow us to maintain key personnel in the safe and cost effective growth of EC Source’s transmission business.”
