The Alberta Electric System Operator has ended the grid alert issued over the weekend after returning to normal market conditions.
AESO says grid alerts are only issued when the power system is under stress and the service is preparing to use emergency reserves to meet the high demand as a way to mitigate the possibility of more drastic emergency measures to balance the system.
AESO adds that temporary rotating power outages could be implemented during grid alerts to ensure the system’s reliability; however, outages are only used as a “last option.”
