Yukon Energy will build two new thermal power centres and one new substation in the Whitehorse area to meet electricity needs until 2040.
Demands for electricity in the Yukon are increasing faster than firm sources of renewable electricity can be built. The Yukon’s population is growing and, with it, the demand for electricity. As Yukoners continue to transition away from fossil fuels for heating and transportation, that demand will only rise.
In the next five years, Yukon Energy will focus on increasing the supply of dependable winter power to meet growing demands and build a stronger, more resilient power system. To do this, we know that thermal capacity, new substations and more transmission and distribution assets are required to meet the needs of Yukoners. While it might seem counterintuitive, thermal resources will play a crucial role in providing the stability needed to safely integrate more community solar and wind resources to the Yukon grid.
On our path to 2050, we want the flexibility to be able to respond to our electricity needs and integrate emerging technologies as they become available. If we reach a point where these thermal assets are no longer required, we will be able to sell or move them, given their modular set-up.
The new Whitehorse Power Centres will serve three main purposes:
Yukon Energy will build two new thermal power centres and one new substation in the Whitehorse area to meet electricity needs until 2040. A site for a potential third thermal power centre, to be used as contingency, will also be assessed through the Yukon Environmental and Socio-economic Assessment Act (YESAA). Collectively, these four sites and each of their respective transmission connections to the Yukon grid make up the scope of this project. The power centres will provide up to 105 megawatts of winter capacity and nearly double the size of the Yukon’s winter power system.
This work will be carried out in phases, starting with the YESAA assessment process in 2025.
Completion phase | Description | Expected in-service date |
---|---|---|
South Power Centre Build | Construct south power centre with 15 MW of capacity. | Winter 2027 |
North Power Centre Build |
|
Winter 2030 |
Expand Power Centres | Add incremental capacity to the north power centre as needed and/or construct second north power centre if expansion of existing north power centre built in Phase 2 is not feasible or demand for power is expected to exceed capacity limits at the north site. | Winter 2035 |
All sites for the Whitehorse Power Centres are located within the Traditional Territories of Kwanlin Dün First Nation and Ta’an Kwäch’än Council, and the Municipality of Whitehorse or within rural areas directly adjacent to Whitehorse municipal boundaries. Yukon Energy has identified ten potential sites for the three generation centres and one site for the substation. These sites will be narrowed down prior to submitting our Project Proposal to the Yukon Environmental and Socio-economic Assessment Board.
