Currently, provincial systems are not completely isolated, but the level of integration is very limited. However, integration provides benefits in terms of managing variable energy resources, such as wind and solar power. Having a larger region for managing these resources is more efficient. Each province has its advantages and drawbacks. For example, in British Columbia, wind potential is slightly lower than in Alberta. Interconnection can thus benefit consumers in each province.
Integration does not necessarily have to occur under all circumstances. However, since the current level of integration is very limited, our view is that increased interconnection would be beneficial.
