Ontario's Supply Mix
A clean, reliable and affordable supply of electricity requires a diverse range of generation sources. As Ontario ends the use of coal as a source of electricity generation, renewables, nuclear and natural gas will make up the province's energy supply mix. In 2013, forecast electricity production in Ontario is: 59 per cent nuclear power, 28 per cent renewable sources, 11 per cent natural gas and 2 per cent coal. The 2025 forecast for Ontario's energy mix is 42 per cent nuclear, 46 per cent renewables and 12 per cent natural gas. None of Ontario's electricity will come from coal.
- Ontario will phase in wind, solar and bioenergy over a longer time period, with 10,700 megawatts online by 2021.
- Ontario will increase the province's hydroelectric portfolio to 9,300 megawatts by 2025.
- A new, competitive procurement process for future renewable energy projects larger than 500 kilowatts will be developed. It will consider local needs and opportunities for Aboriginal participation.
- By 2025, it is expected that 20,000 megawatts of renewable energy will be online - representing nearly half of Ontario's installed capacity.
- Bioenergy facilities can provide flexible power supply and support local jobs in forestry and agriculture. Ontario will include opportunities to procure additional bioenergy as part of the new competitive process.
- Nuclear refurbishment will begin at the Darlington and Bruce Generating Stations in 2016.
- 9,000 additional people would be employed during the refurbishment period, bringing the total number of people employed in Ontario's nuclear sector to approximately 25,000.
- Ontario will not proceed with the construction of two new nuclear reactors at the Darlington Generating Station. The province will continue to work with Ontario Power Generation (OPG) to consider new build in the future.
- During refurbishment, both OPG and Bruce Power will be subject to the strictest possible oversight to ensure safety, reliable supply and value for ratepayers.
- Nuclear refurbishment will follow seven principles that have been established by the government, such as minimizing risk to the government and ratepayers, and ensuring that operators and contractors are accountable for refurbishment costs and schedules.
Natural Gas and Combined Heat and Power
- Natural gas-fired generation will be used flexibly to respond to changes in supply and demand. New natural gas-fired generation is not required to supply province-wide electricity needs at this time.
- Combined Heat and Power can be an effective way to use natural gas to generate electricity while providing useable heat or steam for district heating, agri-food or other purposes. Future procurements will focus on efficiency and regional needs.
