2024 LTO Preliminary Update & Request for Feedback | Nov. 15 - Dec. 6, 2023


The AESO is continuing the development of the 2024 Long-term Outlook (LTO) to support the AESO’s mandate to provide for the safe, reliable, and economic operation of the Alberta electricity system. At its core, the 2024 LTO will focus on market fundamentals including demographics and employment, existing industrial energy needs, electrification of different economic sectors, utilization of existing resource mix and economic additions based on decarbonization-oriented policies. The 2024 LTO is the AESO’s forecast of Alberta load and generation requirements over the next 20 years and is used as one of many inputs to guide transmission system planning, market evaluations, system reliability including resource adequacy.


On January 3, 2023, and June 6, 2023, the AESO provided notice and sought written feedback from interested stakeholders on their perspectives regarding the scope and input assumptions of the proposed long-term outlook analysis. The AESO received responses from various stakeholders and is grateful for the insightful perspectives shared. The primary intent when soliciting stakeholder feedback was to enhance modeling that the AESO will complete for the outlook. The AESO posed several questions seeking stakeholder perspectives regarding government policy, economic prospects, electric load, and generation supply that may guide the 2024 LTO.

The intent of the November 15, 2023, information release is to present the updated preliminary modelling results to stakeholders for input and discussion. The feedback request is intended as a follow-up and seeks any additional stakeholder insights and comments that the AESO will consider prior to the completion of our analysis and final publication of a report in the second quarter of 2024. Stakeholder feedback received will similarly be compiled and posted and the AESO will subsequently provide a summary directional update.
