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).
