The Council is developing its next power plan. Throughout the process, we’ll keep you informed on important milestones, the methods and analysis, and other work as it becomes available.

Scenario analysis

Scenario analysis is one way to account for uncertainty in the power planning landscape by evaluating the potential impacts of changing key assumptions. The Ninth Plan will have two priority scenarios with a range of sensitivities to be explored:

1. New Resource and Transmission Risk (and video, Feb 2025)
   Broad scenario to explore uncertainty around resource availability, resource costs, and transmission availability

2. Changing Hydro Operations (and video, Aug 2025)
   Exploring the implication for power system needs with uncertainty around future hydro operations.

Methodology primers

These primers summarize planned methodologies for developing the Ninth Plan.

• Load Forecast (and video, Aug 2024)
  The Council is required to develop a 20-year demand forecast as part of its plan. This presentation walks through the updated approach for the Ninth Plan.
• New Resource Options – These presentations describe the Council’s approach to developing new resource options to be considered in the plan:
  • Conservation (and video, July 2024)
  • Demand Response (and video, Sep 2024)
  • Distributed Solar (and video, Aug 2024)
  • Generating Resources (and video, Aug 2024)
