While visiting my in-laws last week, I took a day trip down to the Garrison Dam for a tour of the hydroelectric power plant.  I wasn’t sure how much I’d really get to see, not knowing the security stance of those type of places these days.  However, I was pleasantly surprised.  Not only did we see the generator floor, but also the drive shafts below and the penstock room where the huge 24-foot diameter pipes enter the power plant from under the dam.

I also tried to set up a tour of the Great Plains Synfuels Plant near Beulah, North Dakota, but I was not able to make the scheduling work.  That will be on the to-do list for next year, I suppose.  On one of my next trips up into Wyoming I plan to tour the Laramie River Power Station, which actually serves both the east and west U.S. power grids.
