Here's a closer look at the 27.6kV riser and the small substation.

On the small dam sites Minnesota Power has, the generators in the power stations are all original (1900s), so they put out 2400V delta (or so I was told) which is stepped up to 34.5 kV in a small substation outside each dam. 6600 or 6900V is another old school generator voltage as well.

It would appear that there is a metal enclosed switchgear to the left which probably houses a fused load interrupter switch, and a unit type step up transformer on the right.

I was thinking this was a step-up sub for the dam. I'll have to get a close look at it some day to see what voltage it's stepping up to 27.6kV. It's most likely 2.4kV, but I've seen some dams that put out 4.4/4.6/4.8kV as well.

I bet the old dam from the Connecticut Power Company in Falls Village may still put out 6.6kV. The subtransmission grid in that area originally ran at 6.6kV, but the voltage was doubled to 13.2kV in the 1910's. The 13.2kV grid still stands to this day, as far as I know.
