New technologies are transforming the way we produce and use electricity. The IESO is at the forefront of this change, driving and guiding the electricity sector’s evolution. See how Ontario’s power system is transforming.
Governments, communities and business are exploring ways to shift away from fossil fuel-based energy, and looking to clean electricity systems to power the transformation. With one of the cleanest supply mixes in North America, Ontario has an advantage that will help drive broad emissions reductions in the system as other sectors of the economy decarbonize.
The Pathways to Decarbonization report explores the many elements involved in achieving these goals in responding to the Minister of Energy’s request to evaluate a moratorium on new natural gas generation in Ontario, and to develop an achievable pathway to decarbonization in the electricity system.
The scenarios presented in the report identify potential opportunities and challenges to consider, particularly as demand for electricity grows and Ontario’s resource mix evolves. While not plans for the future, they were developed using the tools, methodologies and expertise of the electricity system operator, and they provide valuable insights into the sheer scope and magnitude of the effort that will be required.
Included in this report:
Two scenarios describing the potential results of a 2027 moratorium on natural gas generation in Ontario’s electricity sector, and the resources and timelines needed to decarbonize Ontario’s electricity system.
A summary of the dependencies, risks and opportunities involved in the transition to decarbonization.
Actions to help ensure Ontario can both manage uncertainty and seize new opportunities as they emerge.
