In 2023, two of the six diesel engines in downtown Dawson City will reach their end-of-life. The combined capacity of these two engines is 2.5 megawatts. We will replace the two end-of-life engines with one new 2.5 megawatt diesel engine. The new engine will be installed at our substation in…
Learn moreten years in the making The proposed Southern Lakes Enhanced Storage Project would see us storing more water in Marsh, Tagish and Bennett lakes in the fall and early winter each year. to generate more renewable electricity later in the winter, when it’s needed most. After ten years of research, public engagement and…
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 2020, 86 per cent 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 grid…
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 moreFall 2022 update: In February 2022, the Mayo Lake Enhanced Storage Project was rescoped to include only the removal of remnants of an old coffer dam at the outlet of Mayo Lake. A decision was also made to put the project on hold and to include it as part of…
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 moreConstruction has begun on the new grid-scale battery storage system on Robert Service Way near the Alaska Highway. The new battery will help Yukon Energy meet peak demands for electricity during the winter, burn less diesel fuel and improve the reliability of the Yukon grid. The battery site is located on Kwanlin…
Learn moreThis project was completed in December 2021 on budget and COVID-free. It was needed to improve power quality and reliability, improve public safety and enable future growth around Mayo and Keno. The Mayo to McQuesten Transmission Project consisted of replacing the 65-year-old transmission line between Mayo and the McQuesten substation and adding system…
Learn moreConstruction is underway We will be installing the substation's transformer between November 9 and November 12, 2022. Part of this work will require us to operate machinery for a continuous, 48-hour period. During this time, the sound you will hear will be equivalent to the sound of a truck idling. If you…
Learn moreBuying power from the Atlin Hydro Expansion project is one of three key potential projects outlined in our 10-Year Renewable Electricity Plan. When complete, the Atlin Hydro Expansion project will increase the amount of dependable renewable hydroelectricity available in Yukon to meet winter peaks for power and growing demands for clean…
Learn more2021 flooding in the Southern Lakes led to boat lock damage. Last year’s high-water levels and flood conditions in the Southern Lakes caused significant damage to the Lewes River Control Structure boat lock and island. The Lewes River Control Structure is a critical piece of energy infrastructure that helps us…
Learn moreRenewing our thermal permit In 2023, we’ll be submitting a proposal to renew our existing air emissions permit in Whitehorse. We need an air emissions permit to run our diesel and liquified natural gas (LNG) generators at the Whitehorse Rapids Generating Station on Robert Service Way. We use these generators…
