Based on the images, they’re making good progress on clearing the river channel below. Also, they seem to be progressing along nicely at reinforcing the end of the remaining spillway for future use. My hope would be that they harden it sufficiently that they can use the spillway with little to no erosion. It will remain a significant tool through the thawing season.
I noticed that they were also doing work to temporarily relocate a power transmission line. I think that 1 of the 3 lines coming out of the plant powerhouse has been removed, and another relocated to the tower higher up the hill.
From an electrical standpoint, 2 lines (I think that they are 230 kV circuits ((which should make them roughly capable of 600-800 MW capacity per circuit, depending on wire size)), but not 100% sure) should be able to carry the plant’s output, but with insufficient redundancy. We always try to operate the power system to the next single contingency, and the failure of one of those two lines would limit plant output. Getting the third circuit back in service would be very helpful to add reliability to the plant’s output (purely from the electrical standpoint).
outflow now 7000 cfs at 8am local time
7080 cfs through the plant for hour ending 0900 PST. They’re ramping up. Not sure if they’re running the 3 units up to full output, or if they’ve brought a 4th unit on line.
