Furnaces and heaters working overtime thanks to the extreme cold weather across the province have caused a near record-breaking demand for power, according to the Alberta Electric System Operator.
As an extreme cold warning issued by Environment Canada remains in effect across the province, the cold snap has affected the operations of some generation facilities and low wind across the province prompted the AESO to active an Energy Emergency Alert (EEA) protocol Monday evening.
An EEA is based on a 0-3 tiered alert system with protocols and processes to balance supply and demand for power. Zero is normal conditions.
At 5:18 p.m. Monday, AESO declared an EEA 1 followed by an EEA 2 at 7:15 p.m. While both alerts were issued, power needs continued to be met across the province but AESO had to dip into reserves, AESO said in a release Tuesday.
If AESO has to declare an EEA3, it’s anticipated power would be lost in parts of the province until generation returns to the grid or power usage is reduced to a point where supply and demand can be balanced.
However, AESO did not specify what areas could be affected if a level three is declared.
As the extreme cold weather — with Environment Canada warning the coldest wind chill values will be between minus 45 and minus 50 — continues into the week, AESO said they are closely monitoring the system and will notify Albertans if the grid conditions worsen.
Energy-saving tips
Energy conservation tips include:
- Turn off unnecessary lights and electrical appliances
- Minimize the use of air conditioning/space heaters
- Delay the use of major power-consuming appliances such as washers, dryers and dishwashers until after the peak hours of 5 p.m. — 7 p.m.
- Use cold water for washing clothes — most of the energy used goes to heating the water. Only running full loads helps, too
- Cook with your microwave, crockpot or toaster oven instead of the stove
- Limit the use of kitchen or bathroom ventilation fans
- Use motion-detector lights in storage areas, garages, and outdoors when possible
- Work on a laptop instead of a desktop computer — laptops are more energy-efficient than desktop units
Air quality
Edmonton’s air quality health index was sitting at a 3, or low risk, on Tuesday but is expected to climb to a 4, or moderate risk, on Wednesday.
For those brave enough to do outdoor activities, it’s recommended to adjust appropriately by reducing intensity, duration and more frequent rest periods.
The city is also asking residents to look out for those in need during the cold snap. Call 911 for someone in serious distress or 211 for non-emergency support. Donations can also be made to one of Edmonton’s social agencies.
