With the windchill plunging into the -40 C range and with limited daylight hours, Alberta set three records in a row for electricity consumption.

The Alberta Electric System Operator (AESO) said the province used a record hourly average amount of electricity between 5 and 6 p.m. on Dec. 8, reaching 11,442 megawatts (MW).

That number surpassed the Dec. 7 record of 11,404 MW and the Dec. 5 record of 11,400 MW.

The AESO said the uptick in demand was due to “cold weather, reduced daylight hours and the convergence of Christmas lighting load at homes, businesses, malls and buildings across the province. Tweet This

“Another factor that contributed was the low market price for electricity – this prevented price sensitive industrial facilities from going offline during peak hours.”

AESO said the average wholesale price for electricity during that peak hour was about $30 per megawatt hour. The agency also said it was not concerned about grid reliability during that time.
