    Section 502.11

    New Section 502.11 of the ISO rules, Substation Technical and Operating Requirements

    Recently Posted Materials 


    The AESO began consultation on Section 502.11 of the ISO rules in 2015. In 2019, the proposed development was put on hold due to other priorities. The AESO continues to assess the priority of the development of an ISO rule related to technical requirements for substations and will re-engage with stakeholders in a new consultation when it determines that it is appropriate to move forward with this initiative.

    The AESO appreciates the participation of stakeholders in the consultation process. 


    Proposed new Section 502.11 will define the minimum technical requirements for the design, construction and operation of transmission substations and will apply to only to new transmission substations or new equipment installed at existing transmission substations undergoing substantial modifications.
