The MYM-513 line provides power to rural customers within a 40 km radius, with limited backup feed options. Approximately 1 km of the line was submerged in a slough, and with spring ice breakup expected in six months, the reliability risks were increasing. The project scope was divided into three phases, prioritizing risk mitigation, as completing the entire 33 km, $2.4 million project in six months was impractical.
- Phase 1: Installing screw piles along the new route during winter, as required by environmental regulations. This would give SaskPower the option to expedite Phase 2 if spring ice damaged the line.
- Phase 2: Construct the first 20 km of the line along the new, dry land route.
- Phase 3: Replace 13 km of aging #2 Sparrow line to create backup feed options.
The three project phases took place over multiple years with different team members involved. To manage the project, an initial planning map and a three-column scope of work description were created and saved in the project directory. After addressing the immediate reliability concerns, the project was designed to add more stakeholder value:
- Deferred capital costs at Rosthern by offloading 750 kVA from its overloaded substation
- Replaced approximately 15 km of poles nearing the end of their lifecycle
- Improved reliability and safety by eliminating an abnormal protection scheme
- Reduced the number of overhead highway crossings on Highway 40
- Saved $80-100k for customers needing to upgrade from single-phase to three-phase service
- Collaborated with the RM to develop an all-weather road servicing the town well and the new power line
