Kathleen Substation Renewal

An investment in the Kathleen Substation to better serve our customers.

FAQ

  • Why is the Kathleen Substation being updated?
    • Kathleen is a grand old lady by industry standards—over 60 years old. The Substation went into service in the mid-to-late 1950’s, and at that time, it was “state of the art”. But technology has changed, the distribution system has new challenges, and it’s time to replace the old equipment with new.
  • What is going to be updated?
    • The updates will improve power supply stability and reliability as well as enable us to more quickly and easily reroute power in the event of an unplanned outage. The Kathleen Substation renewal coupled with a planned renewal of our Cressy Substation in 2021 will enable us to eliminate three other smaller substations in our system. Essentially, we are centralizing to these “hubs”, while also looping our 44KV power supply, building redundancy.
  • How will this renewal affect my neighbourhood?
    • After this project is complete, you and your neighbours will have a more stable, reliable power supply. You will also notice some external physical changes to the existing substation:
    • •  Overhead infrastructure on the property will be removed
    • •  Installation of safer pad-mounted equipment
    • •  The historic building will be preserved and continue to house power & control equipment
    • •  We will endeavour to maintain as much of the cedar hedge as possible
    • During the 2018 construction season, neighbours in the immediate area of the substation will notice some signage added to the existing fence, which will remain as a construction barrier. Throughout the construction period, you may see an increase in heavy truck traffic.
  • When will I notice things happening?
    • You may have noticed an increase in planned power interruptions in your area. During the summer of 2017, we started doing “prep work” for the renewal project. We will continue to plan interruptions when necessary to safely proceed with the upgrades.
    • We have already begun converting transformers in the area to 12KV, from their current 4KV configuration, and will continue to do that until they are all modified.
    • In April, we will start decommissioning the old aerial equipment and begin the civil work needed to prepare the site for the installation of the ground-level pad-mount equipment. The civil work will start late May-early June and will take about two months to complete.
  • When will the project be completed?
    • The project is expected to be completed by the end of October 2018, with all new equipment in service and functioning by that time.
  • How many customers will be affected?
    • Approximately 4600 customers will be directly affected by the Kathleen Substation Renewal Project. These are homes and businesses that receive their electricity directly from this particular substation.
    • However, just over 10,000 customers will enjoy service improvements as a result of the 4kv to 12KV conversion overall.
  • How much will the project cost?
    • Modernization of the 60+ year old Kathleen Substation is projected to cost roughly $3.85 million. This project has been incorporated into our regular annual capital budget.
