For most of the year, we rely on hydro for our energy supply, with small amounts of electricity being produced by wind. However we do use back-up diesel generation during power outages, to supplement our hydro in very cold weather, and during droughts.
Yukon Energy currently has diesel generators in Whitehorse, Mayo, Dawson, and Faro.
We don't like to use diesel; it's more costly and it produces greenhouse gas emissions. Because of this, we work hard to keep our use of diesel to a minimum. Close to 99 percent of the electricity we produce is from renewable sources.
That being said, as an isolated grid in one of the planet’s least-forgiving environments, a reliable backup system is crucial.
Thermal (both diesel and LNG) are being considered in the work we are doing our 2016 Resource Plan.
