    Hanna Region Transmission Development

    On August 14, 2009, the AESO filed its Needs Identification Document (NID) for Transmission System Reinforcement in the Hanna area with the Alberta Utilities Commission (AUC).

    On April 29, 2010, the AUC approved the AESO’s NID. The AESO also filed two amendments to the NID approval in 2010, both were approved by the AUC.

    Please see the documents below for more information on the need for this development.

    AltaLink Management Ltd (AltaLink) and ATCO Electric Ltd (ATCO) are the transmission facilities owners (TFO) in the area. While the AESO is responsible for identifying that transmission system development is needed, AltaLink and ATCO are responsible for detailed siting and routing, constructing, operating and maintaining the associated transmission facilities. Stage I developments have been constructed by the TFO and are in operation. Stage 2 developments are currently on hold. Please visit AltaLink’s website at and ATCO’s website at for further information.
