    Central East Transfer-out Transmission Development

    The existing transmission system in the central east area of the province is reaching its capability limits. The AESO has identified the need to enable additional renewable generation integration capability, and to enhance transmission system reliability.

    Two transmission facility owners (TFOs), AltaLink Management Ltd. (AltaLink) and ATCO Electric Ltd. (ATCO), own, operate and maintain the transmission system in the Central East Transfer-out Transmission Development (CETO) project area. While the AESO is responsible for identifying the need for transmission development and the proposed transmission development to meet that need, AltaLink and ATCO are responsible for detailed siting and routing, constructing, operating and maintaining the associated transmission facilities within their service territories. 

    On August 12, 2020 the AESO filed its Needs Identification Document (NID) for the CETO Transmission Development with the Alberta Utilities Commission (AUC).

    Please see the document(s) below for more information on the need for this development.
