Lovell-to-Yellowtail transmission line rebuild Phase 2 update

Insulation is being used to isolate the wire in the air from the equipment on the ground, as part of Phase II of the Lovell-to-Yellowtail transmission line rebuild project, March 26, 2013

Contractors continue rebuilding two 115-kilovolt transmission lines as part of Phase II of the Lovell-to-Yellowtail project. With work in the Big Horn Canyon National Recreation Area complete in fall 2012, the construction contractor started removing the No. 2 line south of the NRA in Wyoming, March 25, 2013.

Crews have about 10 miles of the No. 2 line down and are working on setting new structures in cultivated fields before irrigation of farm land begins.

While crews work on the No. 2 line, the Lovell-to-Yellowtail No. 1 transmission line continues to deliver power from Yellowtail Dam.

The upgrades to the Lovell-to-Yellowtail transmission lines No. 1 and 2 are needed to replace the original lines built by the Bureau of Reclamation in 1956 and 1966.

T-line construction continues even in winter

When you think of Wyoming and Montana in the winter, you might think “cold”—cold enough that you wouldn’t want to be outdoors working on the construction of a transmission line. But that’s exactly what Western crews will be doing this winter.

Crews recently wrapped up rebuilding the Lovell-to Yellowtail No. 1 and No. 2 115-kilovolt transmission lines in the Big Horn Canyon National Recreation Area in Wyoming and Montana. They expect to begin reclamation of unneeded access roads soon. In Feb. 2013, they will begin rebuilding the sections of the lines north and south of the NRA.

The Lovell-to-Yellowtail transmission lines are located between Lovell, Wyo., and Yellowtail Dam, Mont., and help provide the reliable transmission of Yellowtail Dam’s generation.

Linemen de-energize line for safety of Corps construction, part of American River Common Features project

Western’s linemen keep the agencies transmission lines and structures maintained so the system can reliably deliver electricity to cities and towns throughout the West. Sometimes this job requires Western to de-energize a line for maintenance of the line or working going on below the transmission line.

U.S. Army Corps of Engineers’ Todd Plain snapped this photo of Western linemen de-energizing the high-voltage power line at dusk for the safety of the workers below. Construction crews worked during the night constructing the seepage cutoff wall (part of the American River levees) underneath the line. This is part of the Corps American River Common Features project, a joint flood risk reduction effort between the Corps, the state’s Central Valley Flood Protection Board/Department of Water Resources and the Sacramento Area Flood Control Agency.

Enbridge takes up MATL line construction

Taking another step toward bringing renewable energy to market, this month contractors got back to work on the Montana Alberta Tie Limited project.

After receiving a notice to proceed on construction Jan. 10, Renewable Energy Systems Americas employees, hired by Enbridge, got boots on the ground quickly and began remediation work on some existing structures and line near Sweetgrass, Mont.

With 60 percent of the transmission line and substations already completed, Enbridge and RES are continuing to make progress on the line north of Marias River.

Funded partially through Western Area Power Administration’s Transmission Infrastructure Program, Enbridge expects to complete the 214-mile, 230-kilovolt line in 2012.

“Enbridge is committed to quality construction of the line and timely completion of the project,” said Vi Michaelis, Western’s project manager for MATL. “We are very encouraged by the construction restart.”

Once completed, MATL will interconnect the 189-megawatt Rim Rock wind power project, which announced its notice to proceed on construction Jan. 9.
