    Energy Conservation

    Different factors contribute to tight supply conditions and the use emergency reserves to meet demand, including:

    • Extreme temperatures that increase demand for heating or cooling
    • Time of day or wind conditions impacting solar or wind generation
    • Unplanned transmission disruption or generation facility outages
    • Uncontrollable events like severe weather or downed power lines

    During grid condition changes, AESO System Controllers and industry partners take action to maintain reliability that may include:

    • Using emergency reserves
    • Reducing or suspending exports or energy sales
    • Cancelling transmission maintenance
    • Implementing voluntary curtailment programs, where participants reduce energy use to predetermined levels
    • Requesting emergency imports
    • Initiating temporary rotating power outages as a last resort

    Energy Conservation Tips

    • Summer

      Summer Peak Hours (5:00 - 9:30 p.m.)

      • Delay running energy-intensive appliances (e.g., washers, dryers) until off-peak hours
      • Postpone charging electric vehicles
      • Use a microwave, air fryer or slow cooker instead of an electric stove
      • Turn off unnecessary lights, ventilation fans and appliances
      • Reduce air conditioning

      Small actions add up, regardless of the time of day:

      • Wash clothes with cold water and full loads
      • Use a laptop instead of a desktop for improved efficiency
      • Opt for motion-sensor lights in garages or outdoor areas
      • Unplug devices when not in use or use power bars to shut off multiple devices
      • Use ceiling fans to maintain consistent temperature
      • Adjust curtains or blinds to block sunlight in summer
      • Perform regular maintenance on HVAC systems and clean filters
      • Seal gaps around doors and windows to prevent air leaks
    • Winter

      Winter Peak Hours (4:00 - 7:00 p.m.)

      • Delay running energy-intensive appliances (e.g., washers, dryers) until off-peak hours
      • Postpone charging electric vehicles or plugging in block heaters
      • Use a microwave, air fryer or slow cooker instead of an electric stove
      • Turn off unnecessary lights, ventilation fans and appliances
      • Lower the thermostat
