Notice to Our Members in the Sequoyah and Foyil Areas:
Recent increased load on the Feeder out of the Sequoyah Substation that feeds the Foyil and Blue Creek area have necessitated an immediate upgrade to the line. A contractor for VVEC began work on the line the beginning of June. Since that time we have incurred a few unexpected outages that we are working hard to alleviate. The 1st phase of the work is scheduled to be completed around the 4th of July. This is the most difficult section of the line as much of it is not near any roads making access difficult.
When upgrading a live line certain precautions have to be taken to protect the line workers . That means changing the fault current protection schemes, so if there is an accident the line is de-energized rapidly. However, the downside to these new settings is the line is now susceptible to rapid de-energization from line events that would not have affected the line before. An event that would have flickered or maybe a slight dim (not even noticeable to the eye) may cause the breaker to open, thus causing a crew to have to be dispatched to the area to restore.
The morning of the 9th the transmission line that serves the Sequoyah substation blinked causing the breaker to open because of the protective scheme. Later in the same day the contract crew doing the upgrade work had a line slip that contacted another line and knocked the line back out. On Saturday the 12th the protective scheme was set to normal since there were no crews working, however, two of the lines on a temporary arm got together and caused the line to go back out. The line was in the area where access is difficult so it took longer than they expected to get it restored. Then Monday the 14th we get another blink on the substation transmission line that opens the breaker again because of the protective scheme. We are talking with our power supplier to get answers on the transmission line blinks.
We know the loss of power is aggravating, especially when the weather is hot. We absolutely do not want your power off (ever) and are doing all we can to get these power interruptions stopped.
Thank you for your patience!
