  • ENMAX Power 69kV - Calgary, AB

    Surprised this hasn't been yukked yet! Most of the 69kV grid was either yukked with post insulators within the last few decades or been upgraded to 138kV standards.

  • ENMAX Power Substation No. 27

    There are some goodies in this substation, such as those circuit breakers! Both 69kV/13.8kV transformers were manufactured by Westinghouse.

  • ENMAX Power Substation No. 27

    This substation steps 69kV down to 13.8kV.


  • ENMAX Power Substation No. 27

    This is the last substation of it's kind left in Calgary. The other three 69kV substations have been yukked out.

  • ENMAX Power 69kV - Calgary, AB

    Circuit 16.61L terminating at Substation No. 27 in the back.

  • ENMAX Power 69kV & 13.8kV - Calgary, AB

    I'm curious to know if ENMAX plans to up their distribution voltages from 13.8kV to 34.5kV as they have been putting up larger strains and insulators recently. This is also the section of the 69kV system that was yukked out this past March.

  • ENMAX Power 138kV, 69kV & 13.8kV - Calgary, AB

    Circuit 13.60L passes under 11.81L near the intersection of Edmonton Trail.

  • ENMAX Power 69kV & 13.8kV - Calgary, AB

    This section of line was yukked a few years back.


  • ENMAX Power 138kV - Calgary, AB

    This new transmission link in the Bonnybrook area was installed in 2014 as replaced another section of the Calgary 69kV system.

  • ENMAX Power 13.8kV - Calgary, AB

    Here's a good example of the larger strains ENMAX has been using this past year.

  • ENMAX Power 69kV & 13.8kV - Calgary, AB

    It surprises me this line hasn't been completely yukked yet since ENMAX seems to love to give the fiber glass and polymer treatment to lines barely a decade old...


  • BC Hydro 24.9kV - Golden, BC


  • BC Hydro 24.9kV - Columbia-Shuswap A, BC

    The long haul distribution line from Golden to Field gorge crossing.

  • TransAlta Cascade Hydro Plant

    I managed to get a shot of part of the step-up transformer and switchgear in the back of the plant. Power is stepped up to 138kV and sent into Altalink's 138kV system.


  • TransAlta Cascade Hydro Plant

    Just behind those trees is the Cascade plant. This plant was brought online in 1942 and generates 36 megawatts from the Cascade River. The Cascade plant is part of the Bow River Electric System and generates an average of 52,000 megawatt hours each year.

  • TransAlta Cascade Hydro Plant

    That is the single surge tank tower for the Cascade plant. A surge tank is a storage reservoir at the downstream end of a closed aqueduct, feeder, dam, barrage pipe to absorb sudden rises of pressure, as well as to quickly provide extra water during a bri…

  • Fortis Alberta 24.9kV - Canmore, AB

    The recloser from the line has been moved to a point here along the main road.
