  • WMECo brakestomper

    - 4 years ago - 1 comment
    Austin came across an interesting brakestomper recently, and with the name of the town and the distinctive building in the background it was fairly easy to track down: goo.gl/maps/BG2T8MLzgFZcWR4S6 Austin's picture: www.flickr.com/photos/129954339@N03/49614775583

  • A neat muni plant

    It's just a shade too far for me, and likely well out of reach of Justin and Jesse too... goo.gl/maps/MRWLo2ksjSyDDkUc6 Black River Falls, WI

  • Westy manuals!

    - 14 Nov 2017 - 1 comment
    Just found a couple manuals for Westinghouse transformers. This should help us confirm the later versions of Westinghouse transformers (Westinghouse Electric Corp. era): http://www.electricalpartmanuals.com/pdf/transformer/Westinghouse/Distribution%20Transformers/I.B.461001.pdf And fortunately, one from the Westinghouse Electric & Mfg. Co. era: http://www.electricalpartmanuals.com/part_manuals/pdf/transformer/Westinghouse/Distribution_Transformers/IB5922.pdf

  • Only a muni

    - 27 Sep 2017 - 1 comment
    www.google.com/maps/@43.3776423,-99.8584908,3a,75y,269.99h,97.77t/data=!3m6!1e1!3m4!1svlSOCYTcF54YUK2m5VppfA!2e0!7i13312!8i6656?hl=en Looks like the Winner muni forgot to take down an old 2400V-class pole. That pole may also be a remnant of Tri-State Utilities (Foshay), SD Light & Power, or Interstate Power, depending on its vintage.

  • Byllesby-style line with J-D suspensions

    - 05 Jun 2017 - 2 comments
    Matt Weldon found a line in Indiana built to the old Byllesby specifications - but with Jeffrey-Dewitt insulators. Other than the insulators, the construction is nearly a dead ringer for the now-gone Dell Rapids to Pipestone 66kV line! www.insulators.info/pictures/?id=501201796 www.insulators.info/pictures/?id=501200805 www.insulators.info/pictures/?id=501200628

    Just found this book put out by the old Federal Power Commission (now FERC). babel.hathitrust.org/cgi/pt?id=inu.30000047597764;view=1up;seq=1 An excellent source of information - lists ALL the IOUs and munis as well as those coops that were in existence as of 1940. For one, I finally verified that Central Gas & Electric Co. (aka "Cengas") and Central Electric & Telephone were one and the same.

  • Old power plants

    - 12 Mar 2014
    Justin’s article on a long-retired power plant in the Twin Cities that is due to be demolished made me think of all the early power plants I know of that I’ve seen in person - whether they are still serving their original role or not. Appleton, MN / Hering St. north of Thielke Ave Plant retired by Otter Tail; now used by city as storage Benson, MN / Pacific Ave. west of US 12 Municipal plant still in use but re-powered to run on diesel for backup. Virginia, MN / 6th Ave. S & 1st St. S…

  • Minnesota historical info

    - 15 Jan 2014 - 4 comments
    babel.hathitrust.org/cgi/pt?id=wu.89097421655;view=1up;seq=1 Thought this was VERY interesting. There was a LOT of GOOD info in there as to which companies were serving which towns in Minnesota and there were some surprises in there such as finding out East Grand Forks was evidently served by NSP at one time (they must have torn up the franchise and went muni in the '30s).

  • Utility conditions

    While reading Northwestern Energy's Distribution System Infrastructure Plan (addressing needed upgrades to their electric and gas systems in MT), this paragraph on the last page was interesting - "NWE is in a somewhat favorable position – for now. It may already be too late for some utilities for whom the status of disrepair, the costs of catch up and the logistics of widespread infrastructure investment are unmanageable. Others are at the edge, where costly programs and extensive new constru…
