    An informed look ahead

    The AESO publishes a Long-term Outlook (LTO) every two years with updates as necessary. It is our forecast for electricity demand and generation in the province looking out 20 years. We use it to inform our long-term transmission plans and regulatory filings.

    Using a variety of inputs including third-party forecasts and the most up-to-date data available, our outlook provides:

    • Expected growth in electricity demand, and timing
    • Anticipated demand for generation capacity
    • Potential types and locations of new generation

    Long-Term Outlook

    In January 2023, the AESO kicked off the 2024 LTO engagement process. Visit the Forecasting Insights page on AESO Engage for more information and opportunities to participate in this consultation.

    AESO Net-Zero Report

    On June 27, 2022, the AESO published a detailed analysis of the opportunities and challenges involved in eliminating greenhouse gas emissions from Alberta’s power system. The AESO Net-Zero Emissions Pathways report is the first in-depth analysis of the potential implications of a net-zero future to focus specifically on electricity in Alberta. The net-zero pathways analysis will inform and influence future long-term outlooks. Visit the Net-Zero Emissions Pathways Report page for information on this consultation.
