Power on the Edge: Sustaining Yukon’s Closed-Grid Energy Future
Power on the Edge: Sustaining Yukon’s Closed-Grid Energy Future
Yukon’s energy system is as unique as the territory itself. Unlike most other regions in Canada, Yukon operates on a closed energy grid, meaning it cannot import power from neighboring provinces during high-demand periods. This self-reliance presents both challenges and opportunities, especially as the territory faces growing energy demands from expanding industries and communities.
However, innovative energy projects are reshaping the territory’s future. From enhanced hydroelectric storage and cutting-edge battery technology to renewable energy and cross-border collaborations, these initiatives are critical to ensuring Yukon’s grid is ready for tomorrow’s challenges while preserving its environment.
This photo series explores the backbone of Yukon’s energy system, the ongoing projects that are transforming it, and the vision for powering the future in one of the most remote regions in Canada.
The Backbone of Yukon’s Energy – Hydro Power
Hydropower is the cornerstone of Yukon’s energy system, providing over 90% of the territory’s electricity. Yukon Energy operates three hydroelectric facilities: the Whitehorse Rapids Generating Station, the Aishihik Generating Station, and the Mayo Generating Station. Together, they form the backbone of the grid, delivering power to communities across the territory.
Whitehorse Rapids Generating Station
Situated along the Yukon River, the Whitehorse Rapids Generating Station is the largest of its kind in the territory. Operational since the 1950s, this facility has been instrumental in powering Yukon’s capital and surrounding areas. While it is the largest hydro facility in the Yukon, it's production capacity in the winter is reduced from 40 megawatts to 25 megawatts due to the reduced flows of water in the Yukon River.
Aishihik Generating Station
Located about 110 kilometers northwest of Whitehorse, the Aishihik Generating Stations been providing renewable electricity since 1975. It utilizes water from Aishihik Lake. The Aishihik facility is located 110 meters under ground. Annually Aishihik produces about 25 percent of the total energy produced by Yukon Energy. It is notable for being the territory’s only hydro plant capable of operating typically at capacity year-round, thanks to a high-elevation reservoir that stores water for consistent power generation even during winter.
Mayo Generating Station
Serving the northern region of the territory, the Mayo Generating Station started harnesses power from the Mayo River in 1950(Mayo A). In 2011 a new power house project(Mayo B) was completed downstream. This increased the hydro capacity for 5 mega watts to 15 mega watts. This facility plays a vital role in providing electricity to remote communities and supporting mining operations in the area.
Despite their reliability, these hydro stations face seasonal challenges. Winter’s high power demand coincides with low water levels, often requiring newer LNG generators and diesel generators to supplement the power grid demand.

Batteries and Backup – Innovations in Energy Storage
To address fluctuations in power supply and demand, Yukon has invested in its first large-scale battery energy storage system (BESS), located in Whitehorse. This facility acts as a safety net, storing excess energy during periods of low demand and discharging it when demand peaks.
The BESS is also critical for integrating renewable energy sources like wind and solar. By stabilizing the grid, it ensures intermittent power sources can contribute without compromising reliability. This project is a bold step toward modernizing Yukon’s energy infrastructure and could inspire similar systems in remote communities across the territory.

The Rise of Renewables – Solar and Wind Power
Renewables are gaining momentum in Yukon’s energy landscape. The Southern Lakes Wind Project is one of the most promising initiatives, harnessing the region’s consistent winds to supplement hydro and reduce reliance on diesel during low-water periods.
Similarly, solar energy has become a vital power source in remote, off-grid communities. Old Crow, for example, is leading the way with solar installations that provide clean, renewable energy to its residents. These projects not only reduce carbon emissions but also promote energy independence and cost savings.

Regional Collaboration – Atlin Hydro Expansion
Yukon’s energy future is also shaped by partnerships beyond its borders. The Atlin Hydro Expansion Project in northern British Columbia is a prime example. Led by the Taku River Tlingit First Nation, this project aims to increase hydroelectric production in Atlin, with surplus energy delivered to Yukon’s grid via a planned transmission line.
This collaboration highlights the potential for regional partnerships to strengthen Yukon’s energy system while supporting sustainable development for neighboring communities. Once operational, the Atlin project could help offset Yukon’s reliance on diesel generators during peak demand and low-water periods, contributing to the territory’s renewable energy goals.

Bridging the Gap – Industry and Grid Demand
Yukon’s growing economy places additional strain on its closed grid. Industries like mining and tourism, along with new residential developments, contribute to rising energy demands.
Mining, in particular, is a major consumer of electricity, requiring reliable power for both exploration and production. This has led to innovative collaborations between energy providers and industrial partners to implement energy-efficient practices and reduce peak demand pressures.
Projects like the Whitehorse battery system and grid-scale enhancements are helping to bridge the gap between supply and demand, ensuring businesses can thrive without overburdening the grid.

Powering the Future – What’s Next?
As energy demands grow, Yukon is charting a bold path forward. Upcoming projects include expanded renewable capacity, improved storage systems, and enhanced grid resilience. Indigenous partnerships are playing a vital role, fostering sustainable energy solutions that benefit both communities and the environment.
The vision for Yukon’s energy future is one of balance—ensuring reliable power for growing industries and communities while preserving the natural beauty that defines the territory. By leveraging innovation and collaboration, Yukon Energy is creating a system that is both self-reliant and sustainable.

Conclusion
Yukon’s closed-grid energy system is a testament to the territory’s resilience and innovation. As the landscape of energy evolves, projects like the Atlin Hydro Expansion, wind and solar developments, and battery storage systems ensure that Yukon can meet future power demands without compromising its natural heritage or self-reliance.
