Project Descriptions

Each of the projects in our updated Future-Focused Portfolio are critical to meeting the growing need for renewable electricity in Yukon. Projects proposed in this plan are the best mix of projects because they:

  • promote energy conservation;
  • maximize the amount of renewable power generated at existing hydro facilities;
  • connect new sources of First Nation-owned renewables to the grid;
  • store and use excess renewable power generated in the summer to decrease dependency on fossil fuels during the winter;
  • open new markets for surplus renewable electricity generated during the summer; and
  • ensure enough back-up liquefied natural gas and diesel resources are available to provide electricity when renewables are not available.

Existing Resources

All current assets except for three diesel engines set to retire before 2030.

Projects Under Development

Project Name Project Description

Whitehorse Hydro #2 Uprate

Upgrades to key pieces of equipment that allow more electricity to be generated using the same amount of water.
Battery Storage Our battery storage project that received federal funding in 2019.

Electricity purchases from Independent Power Producers

Community-based, renewable electricity projects, primarily owned by First Nations governments and development corporations.

Can produce up to a combined total of 40 gigawatt hours of electricity exported to the grid.

Micro-Generation Program Renewable technologies up to 50 kW each used by residents or businesses for their own consumption, with surplus electricity exported to the grid.

Planned Projects (Based on approvals)

Project Name Project Description
Whitehorse Hydro #4 Uprate

Upgrades to key pieces of equipment that allow more electricity to be generated using the same amount of water.

Incremental Diesel Replacement

Replace retired diesel generators at existing sites.

Southern Lakes and Mayo Enhanced Storage Projects

Expanding the range of water that is allowed to be used in each of these reservoirs.  

Demand Side Management Programs

Programs to help individuals and businesses reduce their electricity use and shift use to off-peak hours.

Potential Future Projects

Project Name Project Description

Moon Lake Pumped Storage

A reversible hydroelectric facility where water is pumped uphill into a reservoir.

Water flowing back down the hill is harnessed to generate electricity in the same way as a conventional hydro plant when needed.

Adds much needed capacity that is required to meet demand during the winter and in emergencies.

Provides a way to store excess renewable electricity in the summer to decrease dependency on fossil fuels during the winter.

Electricity Purchases from the Atlin Hydro Expansion

Sourcing renewable energy from the planned expansion of the Atlin hydro facility owned by Taku River Tlingit First Nation.

Capitalizes on an already existing project.

Presents a near-term opportunity to make more dependable, renewable electricity available in Yukon.

Its close proximity to existing transmission infrastructure keeps project costs reasonable.

Southern Lakes Transmission Network

An upgraded transmission line between Whitehorse and Tutshi–Moon to deliver excess renewable power to the pumped storage facility in the summer and make that power available on the Yukon grid during the winter.

An upgraded transmission line to Jakes Corners allows the Atlin hydro plant to connect to the Yukon grid.

Enables the connection of future community-based renewable projects in southern Yukon to the grid.

Creates the opportunity for future sales of surplus renewable electricity to Skagway.
