Gas pumps freeze at Calgary gas stations [video]
A severe cold snap in Calgary, with temperatures near –40°C, is freezing gas pump hardware and straining Alberta’s already fragile power grid, prompting emergency alerts and $1,000/MWh spot prices. Commenters use the event to compare how internal combustion and electric vehicles handle extreme cold, debate the practicality of heat pumps, propane heaters and alternative battery chemistries, and question whether current grid management and energy policy can support large-scale electrification in such climates. The thread also touches on regional infrastructure choices, from nuclear and wind to home heating and backup systems, highlighting both technical and governance challenges.
Cold, Gas Pumps, and Infrastructure
- Calgary cold snap hit ~-30°C to -40°C; posters say such temperatures occur most winters and strain “everything”: people, vehicles, utilities.
- Gas pumps freezing is attributed variously to:
- Fuel issues: gasoline can become very viscous; composition and additives matter; water in fuel or filters can freeze.
- Hardware issues: pump lubrication, brittle/shrunken metal parts, frozen electronics; older fully mechanical pumps reportedly perform better.
- Some say this level of pump trouble happens briefly most years; others from similar climates don’t recall it and are puzzled, so exact causes are unclear.
- Arctic workaround: pumps enclosed in heated sheds with only hoses exposed.
EVs vs ICE in Extreme Cold
- EV behavior:
- Many reports of 30–50% range loss in deep cold, especially on highways; some models (with good battery heating/heat pumps) perform notably better.
- Batteries do not freeze but reaction rates drop; modern EVs preheat packs and cabins, often via apps.
- Some chemistries like lithium-titanate are cited as cold-robust but niche.
- ICE behavior:
- Gas/diesel engines also struggle: hard starts, thick fluids, fuel gelling, reliance on block heaters.
- Both EVs and ICE vehicles need special provisions in severe winter.
- Proposals:
- Add propane or diesel heaters to EVs for cabin/battery heat; supporters emphasize efficiency and comfort, critics highlight complexity, safety, weight, maintenance, and parking restrictions.
- Heat pumps in EVs seen as standard; debate over their usefulness below about -25°C and whether backup resistive or fuel heat is needed.
Grid Reliability and EV Adoption
- Alberta’s grid during the cold snap:
- Grid alerts, imports from neighboring provinces, and wholesale prices spiking (~$1000/MWh) cited as evidence of underinvestment and mismanagement.
- Wind output was low due to low wind speeds, not cold; some gas plants offline for unclear “cold” reasons.
- EV impact:
- One side claims widespread EV adoption would “destroy” such a fragile grid.
- Others cite analyses (e.g., UK grid) that fully electrified fleets raise total demand ~10%, manageable with smart off-peak charging and vehicle-to-grid.
- Counterpoint: grid expansion and distribution upgrades are slow (decades), and local feeders may be overloaded if many homes add 7 kW chargers; nighttime is not always low-demand in very cold regions due to heating loads.
Policy, Governance, and Alternatives
- Strong criticism of Alberta and, by some, Canada as poorly managed: high electricity bills, frequent outages, and political capture by fossil interests.
- Others reference quality-of-life and healthcare studies showing Canada compares well internationally, while conceding affordability and infrastructure issues.
- Nuclear (especially small modular reactors) proposed for Alberta and oil sands, both for electricity and process heat, as a path to a more EV-friendly, resilient grid.
- Examples from Europe, the UK, Netherlands, and Norway are used to argue that high EV penetration and grid upgrades are feasible but slow and require competent regulation.
