Forecasting

The AESO publishes a Long-term Outlook 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

2021 Long-term outlook scenarios

Keeping with the mandate of providing safe, reliable and economic operation of the Alberta electricity system while facilitating a fair, efficient and competitive market for electricity, the AESO is developing the 2021 Long-term Outlook (LTO).

Over the next six months, the AESO will complete a detailed forecast of the reference case and run the scenarios.

We have solicited feedback from stakeholders that are interested in the 2021 Long-term Outlook in order to understand their perspectives and insights related to the proposed scenario narratives. Their feedback is available below.
