Long-term Transmission Plans

The Long-term Transmission Plan outlines the AESO’s proposed plans for the development of the electricity transmission system over the next 20 years. It describes the transmission facilities required to meet forecast load growth, ensure electricity system reliability, facilitate fair, efficient and openly competitive operation of the electricity market, and support long-term economic development in Alberta.

The AESO takes a proactive, balanced and flexible approach to transmission planning and considers Alberta’s future electricity needs, potential generation additions and relevant economic factors. AESO long-term transmission plans are compliant with all applicable legislative, regulatory and reliability requirements; specifically Section 33(1) of the Electric Utilities Act and sections 10(1) and 10(2) of the Transmission Regulation.
