Toronto Hydro-Electric System Limited has applied to the Ontario Energy Board with a plan to set the amount it charges for electricity distribution in each of the five years beginning on January 1, 2025 and ending on December 31, 2029. Toronto Hydro-Electric System Limited is also applying to clear several deferral and variance accounts by rate riders in each of these years. As part of this application, Toronto Hydro-Electric System Limited has proposed a rate-setting formula and related elements that would set its distribution rates over this period. In subsequent rate applications, this formula would adjust the distribution rates for 2026 to 2029 period according to inflation and the other elements of that formula. If the application is approved as filed, the amount Toronto Hydro-Electric System Limited charges for the typical residential customer using 750 kWh per month and for the typical General Service <50kW customer using 2000 kWh per month would increase in these years by the following amounts:
| Year | 2025 | 2026 | 2027 | 2028 | 2029 |
|---|---|---|---|---|---|
| Residential Bill Impact (per month) | $3.24 | $3.40 | $3.72 | $3.97 | $2.86 |
| General Service < 50kW Bill Impact (per month) | $14.18 | $9.24 | $9.61 | $10.67 | $7.29 |
Other customers, including businesses, are also affected. It is important to review the application carefully to determine whether you may be affected by these changes.

Submit a letter of comment
You can submit a letter of comment that will be considered by the panel deciding the application. Unless the notice states otherwise, your letter of comment will be accepted until the record of the proceeding is closed (which usually occurs with the filing of the applicant’s final reply argument). However, you are encouraged to submit your letter as early in the process as you can. Depending on timing of receipt of letters of comment, the applicant will typically provide a respond to the issues raised in those letters. Your letter will be provided directly to the panel of Commissioners who will be deciding whether the application is approved. The panel will consider your comments in reaching their decision. The panel will only be able to consider comments which relate to issues which are within the authority of the OEB and relevant to the issues being considered by the panel.
