Decarbonization Hub

The Independent Electricity System Operator is preparing an orderly transition from natural gas generation to other forms of non-emitting supply while at the same time meeting our growing energy needs. Check back here regularly to see the latest activities and how you can get involved. 

Ontario's Energy Transition

In Canada, as in many countries around the world, governments are developing policies aimed at achieving a net-zero greenhouse gas (GHG) emissions economy by 2050, including a clean electricity system. Ontario is in a good position to make this transition, but bridging the work of today with the needs of a decarbonized world will be challenging and complex.

We're working on a collaborative approach across all sectors of the economy to decarbonize Ontario’s electricity system to maintain affordability and keeping the lights on.

 

Ontario's Electricity Future Needs

With the release of its 25 year demand forecast, this update shows the progress being made to meet Ontario's future energy needs. This includes the development of new nuclear facilities, procuring renewables and expanding Save on Energy efficiency programs.

New Clean Electricity Supply

Decarbonizing the electricity grid is essential in order to build a clean and sustainable energy future. To take the next step on Ontario’s decarbonization journey, the IESO is targeting 2,000 MW of non-emitting generation - wind, solar, bioenergy and hydro, to be online as early as 2030.

Decarbonizing Ontario

Pathways to Decarbonization

The IESO's landmark report explores possibilities for a moratorium on natural gas-fired generation in Ontario’s electricity system, and a timeframe for decarbonizing Ontario’s electricity supply mix.

Ontario's Electricity System Transformation

Ontario’s electricity system is one of the cleanest in the world and is well positioned to support the electrification of other sectors.

Electrification in the Broader Economy

With electric vehicles is on the rise, homeowners and businesses are considering a switch to electric heating, and manufacturers are beginning the transition from fossil fuel processes to electric alternatives.

Natural Gas Phase-Out Study

In this 2021 report, the IESO examined the possibility of phasing-out natural gas generation by 2030, demonstrating both the complexity and the possibilities of such a change.
