    Alberta Reliability Standards

    Alberta reliability standards (ARS) are the requirements followed by the AESO and Alberta market participants to provide for the reliable operation of the Alberta interconnected electric system (AIES).

    We recommend the adoption of ARS that are based on the reliability standards of the North American Electric Reliability Corporation (NERC), as well as other ARS that amend, supplement or replace the NERC standards. The adoption of ARS that are consistent with NERC reliability standards allows for the reliable operation of the AIES and increases reliability of the whole North American grid.

    Review and stakeholder engagement

    ARS are adopted in accordance with the Transmission Regulation. When developing a proposed ARS, we consider whether the ARS is capable of applying in Alberta and ensure, to the extent reasonable, that the ARS will not require a material change in the framework for the market for electricity.

    After developing an ARS, we engage with market participants that we consider likely to be directly affected by the ARS. We then recommend the Alberta Utilities Commission (Commission) approve the ARS. If we determine that a specific NERC reliability standard is not applicable in Alberta, we recommend the Commission reject that reliability standard.
