Ontario’s System-Wide Electricity Supply Mix: 2022 Data

Apr 26, 2023

Under O. Reg. 416/99 the Ministry of Energy is responsible for providing Ontario’s electricity supply mix data for electricity suppliers. The following table discloses the system-wide electricity supply mix data for 2022. This data must be used by electricity suppliers for the purposes of complying with the disclosure obligations of O. Reg. 416/99 and the Directive. This data should be considered current until further notice.

2022 Electricity Facts
Electricity Source Ontario’s Electricity Mix
Nuclear Energy 51.00%
Water Power 25.10%
Natural Gas* 10.20%
Wind 9.90%
Solar PV 2.50%
Bioenergy 0.40%
Other (non-emitting) ** 0.90%
Total 1
*  Includes Lennox, dual fuel (natual gas/bioenergy) and non-contracted emitting generation consistent with IESO.
**  Other represents a variety of non-contracted fuel types that the IESO is unable to categorize due to a lack of information from Local Distribution Companies (LDCs).
Note:
1.  Components may not sum to the total due to rounding.
2. Figures do not account for the sale and retirement of Clean Energy Credits (CECs).

 

To fulfill the requirements of the Regulation, the OEB presents the information in percentages. To support the changes the IESO has made to the presentation of their distribution-connected data, the supply mix data in the table below is also presented in Terawatt-hours (TWh).
