    Southern Alberta Transmission Reinforcement

    The AESO is responsible for the safe, reliable and economic planning and operation of the Alberta Interconnected Electric System. As such, we have identified current and future proposals for a significant increase in power generation projects throughout southern Alberta, including substantial wind power development. The AESO is currently investigating the need to reinforce the transmission system so that these generation projects can be connected reliably to the provincial grid.

    The Southern Alberta Transmission Reinforcement (SATR) Needs Identification Document (NID) was approved by the Alberta Utilities Commission (AUC) on September 8, 2009. The NID, including all appendices, engagement material and amendments approved by the AUC are located on the Archived Material page. Active projects, including amendments currently under construction or before the AUC, can be found on the Current Projects page.
