There are almost 400 distribution stations in the province. There are 97 stations in the City of Winnipeg, 37 of which are operating beyond their technical limitations; 8 stations are more than 60 years old. We need to replace or refurbish 20 substations in Winnipeg alone, at an estimated cost of $630 million over the next 10 to 12 years.
Outside of Winnipeg, we are making a concerted effort to improve the reliability of service and enhance the capacity of our system. In many cases, we are upgrading distribution stations originally built during the Farm Electrification Program that followed World War II.
In other areas we are adding new distribution capacity to accommodate population and economic growth. This includes upgrading existing new distribution lines, building new distribution and supply lines and building new distribution supply centres.
New and refurbished distribution stations
These distribution stations are required to improve system reliability, supply the growing demand in the local area, and make plans for future growth. Built on existing Manitoba Hydro land, refurbished stations will include expansion of their station yards, new equipment, and the reconnection or relocation of feeder lines. As well, safety improvements are required with the aging equipment to protect our staff.
During construction in these areas, there will be short-term power outages as the new equipment is connected. These power outages will be planned in advance and we will attempt to contact affected customers in advance. General construction noise can be expected for the duration of the project. Some traffic delays and disruptions may also occur.
Dunraven station upgrade
This project involves upgrading power lines originating out of Dunraven Station, which is located at 25 Dunraven Avenue, from 4 kV to 24 kV.
The work will be done in 3 stages:
- New poles, conductor and underground cable will be installed starting this winter until spring 2019. The work will occur in the following streets:
- Des Meurons Street from Essex Avenue to Avondale Road;
- back lane on Clonard Avenue;
- Blenheim Avenue from Egerton Road to Overton Street;
- Dunraven Avenue.
- Once these new poles and cables are in place, electrical service will be transferred to the new 24 kV feeder in 2019. The work will occur in the following streets:
- Imperial Avenue between St. Anne’s Road and Egerton Road south to the back lanes on Avondale Road.
- In 2019, we will continue to transfer services to the 24 kV feeder for the rest of the area and remove old poles. The work will occur in the following streets:
- north of Imperial Avenue between St. Anne’s Road and Egerton Road north to the back lanes on Essex Avenue.
Panet station construction
This new distribution substation will be located on Dugald Road between Dawson Road and Panet Road. The project began August 2018 and will be ready for testing in April 2020. The project includes:
- demolition of a parking lot;
- construction of a new building and station fence;
- installation of substation equipment.
McPhillips station expansion
The project includes:
- fenced yard expansion;
- relocation of the distribution equipment to the new yard;
- replacing 2 existing transformers with 3 new transformers;
- adding a capacitor bank to reduce low voltage conditions;
- construction of a new control building;
- reconnecting feeder lines to the new equipment.
The McPhillips station contains both transmission and distribution equipment. This project will only replace the distribution equipment.
Construction work on the $47.2 million project started in 2016 and will be completed by March 2019.
Mohawk station expansion
This $19.7 million project was started in 2016 and completed in November 2018. Upgrades included yard expansion, a new transformer, a new capacitor bank, and realigning the existing 115 kV overhead line.
St. Vital station expansion
This $51.3 million project was started in 2016 and completed in November 2018. Upgrades included yard expansion, 3 new transformers, a new capacitor bank, and a new control building.
