Bipole III Transmission Reliability Project

 

Approximately 75 percent of Manitoba’s generating capacity is delivered to southern Manitoba via the existing high-voltage direct current (HVDC) Interlake corridor, which is shared by the Bipole I and II transmission lines.

In order to enhance the overall system reliability and dependability of Manitoba Hydro’s power grid, WSP provided professional geomatics services for the construction of 400 kilometers of a 500 kilovolt HVDC transmission line spanning Split Lake to The Pas in northern Manitoba.

  • WSP established 255 kilometers of a project control network of GPS base station locations relative to the Canadian Active Control System and Passive Control Network maintained by Natural Resources Canada.
  • The control network was established in a remote setting, utilizing helicopter, snowmobile, and truck transportation where access allowed.
  • Ongoing field surveys for this project involved the coordination and checking of the right-of-way clearing limits, topographic survey of access and crossings, and final structure construction layout calculation and staking.
  • Project deliverables included control network adjustment and analysis, control sheets for the established monuments, and final structure staking coordinates.
