    • Grid Alert Ended | Return to Normal Operating Conditions

      The Grid Alert ended as of 8:04 p.m. The AESO will closely monitor supply during maintenance on the Alberta-British Columbia intertie, which is ongoing until the end of September. The AESO issues a Grid Alert when we begin to utilize our emergency reserves to maintain a balance between supply and demand. No action was required of the public to manage the temporary supply shortfall.

    • The AESO announced a Grid Alert as of 6:54 p.m. on Monday, Sept. 8, 2025.

      Due to maintenance on the Alberta-British Columbia tie line, a generator outage, and solar dropping off with sunset, we’re currently using reserves to meet demand and maintain system reliability. We will provide an update when system conditions return to normal.
