Long-term Transmission Plan
We publish our proposed transmission development plans every two years in the AESO Long-term Transmission Plan. It explains the general timing and location of transmission facilities required for the next 20 years to meet electricity needs, operate the electricity market, and support Alberta’s economic development.
Our transmission plans are flexible, allowing for potential generation developments and changes in the provincial economy. They are guided by Alberta’s Electric Utilities Act and Transmission Regulation.
2022 Long-term Transmission Plan
The 2022 Long-term Transmission Plan (2022 LTP) identifies current and future needs for a range of possible demand and generation conditions in Alberta and sets out flexible plans to respond.
The AESO has been very focused on reducing future transmission costs using our expertise to identify creative lower-cost solutions and push investment decisions further out in time. This has resulted in between $275 million and $320 million in net present value savings to Alberta ratepayers in 2021. View Cost Management for more information.
