Power Data

Year-end Data Now Available

The mild and wet weather conditions in 2017 led to lower peak days and reduced total demand in Ontario. The data also shows that Ontario’s clean and diverse power supply continues to reliably meet the province’s energy needs, while increased participation in conservation programs, growth of demand response and added generation in distribution networks is changing the shape of demand patterns and helping to evolve Ontario’s electricity landscape.
