Electric Home Heating and EV Demand

Jul 17, 2025  Comment

In our five-year strategic plan, we shared that a single-dwelling home requires three times more electricity when it switches from propane or diesel to electric heat. And when you add an electric vehicle (EV) to the mix, that same home could use five to six times more electricity. 

That raised some good questions from the community, so we want to clear things up. 

These numbers are based on demand, not energy consumption. That means it’s not about how much electricity a home uses over time, but how much it might need at a single point in time, like during a cold winter evening when the heat is on and the EV is charging in the driveway. In those moments, the demand for power can spike to several times higher than a home with oil or propane heat and a gas-powered vehicle. 

This is an important difference. And it actually underlines why thermal resources like LNG and diesel (that can be turned on quickly) are so critical for meeting those peak times when everyone needs electricity at once.  

We're laser-focused on building dependable sources of electricity that can deliver when we need them most, especially during the winter. That’s why we're moving forward with our Whitehorse Power Centres project as a key priority. 

Our road map to 2050 outlines our vision for an even more renewable future; however, it's important to understand the unique challenges we face today with growing electricity demand and an isolated system.  

We appreciate that Yukoners are curious and engaged as we work to build a more robust and reliable grid in the years ahead.
