News Summary

A recent survey reveals that most of Ontario’s electricity utilities have not conducted studies on how climate change could threaten components of the power grid. Despite some progress in making the grid more resilient to extreme weather events, the Ontario Energy Board plans to implement policies requiring utilities to assess their vulnerability to climate-related impacts starting in 2026. The survey, conducted by consulting firm ICF, highlights the need for proactive measures to reduce damage costs and improve grid resilience. Currently, only a fraction of utilities perform climate vulnerability assessments, which integrate historical data with climate model projections to identify vulnerable parts of the grid. The provincial government, in response, emphasizes the importance of strengthening grid infrastructure against climate-related challenges. The Electricity Distributors Association supports these initiatives, acknowledging the need for a more resilient distribution grid across Ontario.
