Hydro Ottawa Limited (Hydro Ottawa) has applied to the Ontario Energy Board (OEB) to increase its electricity distribution rates effective January 1, 2027. Hydro Ottawa has also applied for approval of updated revenue to cost ratios, (which are used in rate-setting to allocate costs to various customer classes), including the 2027 Cost Allocation Model and related revenue-to-cost ratio adjustments for General Service > 50 to 1,499 kW, Streetlighting and Unmetered Scattered Load classes. The requested rate changes are set using an OEB-approved formula, which is tied to inflation, growth, and other factors intended to promote efficiency.
If the application is approved as filed, a typical residential customer and a typical general service customer of Hydro Ottawa would see the following increase:
| Residential (750 kWh) | $3.23 per month |
| General Service less than 50kW (2,000 kWh) | $6.56 per month |
Type: Rates

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.
