Alberta issues second “grid alert” in one day, the third in 24 hours, and fifth in three weeks, and sets another demand record

As Alberta’s internal electrical load creeps up again to close to record levels at supper time on Wednesday, Dec. 21, the Alberta Electric System Operator (AESO) issued its second “grid alert” in one day, its third in 24 hours across two days, and its fifth in three weeks. It did this as the grid’s internal load set another record, exceeding the previous record set two days before.
