Riding Mountain National Park Transmission Line Widening

The 230-kilovolt and the 115-kV transmission lines were constructed in 1964 in a 34 km long right-of-way through Riding Mountain National Park. For the past 50 years, the transmission lines have provided service to customers outside of the park area.

This project involves:

  • widening the right-of-way to meet new reliability standards;
  • redevelopment of the Moon Lake access trail;
  • ongoing operation and maintenance activities;
  • further development of long-term integrated vegetation management plan.


A detailed Environmental Impact Analysis (PDF, 25 MB) has been submitted to Parks Canada as part of the regulatory review process.
