Construction on Rocky Mountain Power’s 100-mile Mona-to-Oquirrh transmission line remains on schedule, and should be completed by May 2013, according to RMP spokesperson Margaret Oler.
The last of the 467 required poles were completed earlier this month, leaving seven segments of line, each about four to five miles in length, to be strung before the final stages of construction and testing can begin. Construction crews will resume work on those segments beginning January 7, Oler said.
The unfinished work is located between Faust Road and the Clover substation, an area that was scheduled for late completion because winter construction will be easier to complete in those locations than in other areas.
Each segment will take a few days to complete, and they will be completed sequentially. Some winter weather-related delays are expected, but once the remaining line is in place, the finishing touches — miscellaneous bits such as jumpers and communications hardware — can be added.
As construction comes to a close, Oler said the project will enter a testing phase before the line will be energized and begin serving customers. Some environmental remediation will also be necessary, but because such work requires warmer weather, remediation may continue after the expected completion date.
Even with the possibility of winter delays, Oler said the line should go into service in May 2013, just before the peak use period next summer.
“Summertime is peak demand for electricity for this area,” Oler said. “We wanted to be sure we would have it in place for the summer season, and we’re very confident that we will be able to meet that set date.”
Once completed, the transmission line should increase capacity and reliability for RMP customers throughout Utah, Oler said.
