Concept Potential Effects and Mitigations Future-Focused Portfolio Research Information Sessions We're committed to renewables. Yukoners have told us they are, too. Each winter, when demand for electricity is the highest, Yukon Energy must use liquefied natural gas (LNG) and diesel to meet peak demands for power because enough water isn't available to…
Learn moreIn summer 2019, we asked for Yukoners' feedback on a proposed new 20 MW thermal generation facility, a project aimed to provide safe and reliabe electricity quickly during loss of hydro generation, peak hours of consumption, low water periods, extreme low temperatures and emergencies. Thank you to everyone who provided…
Learn moreThe Whitehorse hydro plant has served Yukoners since 1958. It was developed to supply electricity to a growing Yukon population. It began with two turbines; a third one was added in 1969, and a fourth in 1985. In the summertime, our Whitehorse hydro facilities can produce 40 megawatts of power.…
Learn moreThe Aishihik hydro plant, located about 110 kilometres northwest of Whitehorse, has provided renewable electricity to Yukoners since 1975. It was built to serve the growing electrical demands of Yukoners and of a large lead-zinc mine at Faro in Central Yukon. The original plant included two hydro units that could each…
Learn moreThe Mayo A hydro facility has served Yukoners since 1951. It was developed to supply electricity to the United Keno Hill Mine at Elsa, about 45 kilometres north of Mayo. It also generates power for other Yukon communities via Yukon Energy’s transmission system. The Mayo B hydro project, completed in…
Learn moreNatural gas is a type of fuel, like gasoline or diesel, used to drive engines or heat buildings. After it is removed from the ground it can be refrigerated to minus 162°C; at that temperature it turns into liquid (referred to as LNG or liquefied natural gas) that takes up far…
Learn moreFor most of the year, we rely on hydro for our energy supply. In 2018, close to 94 percent of the electricity we generated was with hydro. However we do use backup diesel generation during power outages, to supplement our hydro in very cold weather, and during droughts. As an isolated…
Learn moreUprating involves replacing older components of generating equipment with new, more efficient components. The result is that the generator can produce more electricity with the same amount of water. Refurbishments are major overhauls of existing facilities where many pieces of equipment are reaching end of life. Upratings are one of…
Learn moreThe original reservoir at Mayo Lake was developed in the 1950s when Mayo A was built. The lake level was raised about five metres and the current operating regime of 2.59 metres was established. Yukon Energy is proposing to enhance the storage at Mayo Lake by lowering the current licensed…
Learn moreDuring the fall of 2015, Yukon Energy installed a solar energy system on the south-facing wall of our main administration building in Whitehorse. The system, that includes 40 panels of 260 watts each, can produce about 10 kW of renewable energy. It is providing power for at least five percent of our load…
Learn moreWind is another potential option in our "energy tool box". It is renewable and scalable. Most of our wind research to date has focussed on two areas: 1) Tehcho (formerly Ferry Hill) near Stewart Crossing in Central Yukon; and 2) Mount Sumanik near Whitehorse, although as part of our 2016 Resource Planning…
Learn moreElectrical storage systems allow energy generated at one time to be held for use at another time. There are many types of storage, including compressed air, flywheels, hydrogen cells, and capacitors. As an isolated grid, one of the largest challenges we face is meeting peak demands for power during winter…
Learn moreHydroelectricity generation uses the force of falling or fast-moving water to produce power. Small-scale hydro in Yukon would either be a traditional plant with a dam and reservoir to store water, or a run-of-river plant. Run-of-river operations use the natural flow of a river, with little – if any –…
Learn moreThe Yukon government, through the Yukon Development Corporation, has provided Yukon Energy with funding to plan for improvements to the transmission infrastructure in Central Yukon between Stewart Crossing and Keno City. This money has resulted in a shovel-ready project. The section of the transmission line between Mayo and Keno City is…
