The IESO is responsible for planning the reliability of Ontario’s electricity grid, ensuring that everyone in Ontario has access to the electricity they need, when and where they need it. As an essential component to the electricity system, the IESO recognizes the importance of improving long-term high-voltage transmission system planning to better account for the impacts of climate change on the security and reliability of the interconnected grid. Planning decisions must consider both the increasing importance of transmission expansion as an enabler of decarbonization, and the possible impacts of climate change-driven extreme weather events on the future transmission system.
Through this RFP, it is the intent of the IESO to enter into an agreement with a service provider that will support the integration of climate change adaptation and resiliency considerations into the transmission planning process, which includes the processes of identifying transmission system needs and/or opportunities to enhance the transmission system, and evaluating options to address identified needs/opportunities. This work will culminate in a report that describes strategic actions that the IESO should consider taking to better understand and incorporate the impacts of climate change driven extreme weather into its long-term transmission system plans.
