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.

Each scenario goes through a four step process examining market availability, regional needs, resource optimization and a check on adequacy: 

The Ninth Plan will have two priority scenarios with a range of sensitivities to be explored:

1. New Resource and Transmission Risk 
   Broad scenario to explore uncertainty around resource availability, resource costs, and transmission availability

• Scope of the New Resource and Transmission Risk Scenario (and video, Feb 2025)
• Refined Scope of the New Resource and Transmission Risk Scenario (and video, Sept 2025)

2. Changing Hydro Operations
   Exploring the implication for power system needs with uncertainty around future hydro operations.

• Scope of the Changing Hydro Operations Scenario (and video, Aug 2025)
• Needs Assessment (and video, Oct 2025)
