Dominion Power 551 Transmission Line Survey
Surveying Across Difficult Terrain
The transmission line ran across mountains, valleys, and other steep elevations, which posed difficult barriers to the line’s refurbishing.
Within two weeks’ notice, we had as many as four crews in the field to begin staking the line.
While our teams often encountered difficulty accessing points due to the challenging terrain, Dominion was able to begin power line structure construction within three weeks.

Dominion Power’s number 551 transmission line, originally completed in the late 1960s, runs across 100 miles of various terrain from the Mt. Storm substation in West Virginia, to the Doubs substation in Maryland. This 45-year-old line – the first 500 kV line energized in the U.S. – was heavily loaded, and much of its equipment was nearing the end of its useful life. Dominion tasked us with completing the surveying stakeouts under an aggressive schedule. The refurbished line will operate with an increased user capacity of 66%, making more power available to significant portions of the population.
