The Alberta Electric System Operator (AESO) has issued a Grid Alert.

The organization says the alert was issued due to tight supply.

"AESO issues a Grid Alert when the power system is under stress and we’re preparing to use emergency reserves to meet demand and maintain system reliability," AESO states on its website.

Locals are advised to limit their electricity use so more serious emergency measures aren't taken to balance the system, including rotating power outages.

The alert was issued just before 7 a.m. and expected to be lifted around 10 a.m.

AESO added that grid alerts can happen for a variety of reasons, including, extremely cold or hot weather, which drives increased use of heating or air conditioning systems, time of day and wind conditions, which impact the availability of solar and wind-generated energy, as well as unplanned generation facility outages.
