    Ancillary Services procurement

    Ancillary services are essential for providing Albertans with safe, secure and reliable electricity. These services include Operating Reserve, Transmission Must-Run, Black Start services, and Load Shed Service for imports.

    We are committed to using a fair and transparent competitive procurement process for ancillary services whenever possible, as outlined in the AESO Procurement Process.
