    Section 502.11

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

    Notice

    In November 2018, the AESO initiated consultation on the proposed development of an ISO rule that would set out the minimum technical requirements for the design, construction, and operation of transmission substations that are directly connected to the Alberta transmission system. That proposed development has been 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 when it determines that it is appropriate to move forward with this initiative.

    Purpose

    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.
