Hydro One Networks Inc. (Hydro One Networks) and Hydro One Sault Ste. Marie LP (Hydro One Sault Ste. Marie) filed a combined application to the Ontario Energy Board (OEB) for approval of a five-year rate plan for the period January 1, 2028 to December 31, 2032.
Hydro One Networks has applied for approval of the transmission rates it charges for the use of its transmission system and the distribution rates it charges for electricity distribution in each of the five years of the rate plan.
Hydro One Sault Ste. Marie has applied for approval of its charges for using its transmission system on a final basis for 2027 and for the same five-year period.
Hydro One Networks Transmission
The OEB’s decision on the transmission portion of this application will have an effect on all electricity consumers in Ontario. The cost of transmission is reflected in the delivery charges included on customer bills.
If Hydro One Networks’ transmission portion of the application is approved as filed, a typical residential customer and a typical general service customer would see the following monthly increases:
| Customer Class | 2028 | 2029 | 2030 | 2031 | 2032 |
| Residential Medium Density (750 kWh) | $0.50 | $1.28 | $1.49 | $0.89 | $1.53 |
| General Service less than 50 kW (2,000 kWh) | $1.12 | $2.84 | $3.32 | $1.98 | $3.41 |
The changes for customers of other electricity distributors across the province may vary depending on the customer’s electricity usage and the electricity distributor that serves them. Other customers, including businesses, will also be affected.
Hydro One Networks Distribution
The OEB’s decision on the distribution portion of this application will have an effect on electricity consumers who receive electricity from Hydro One Networks’ distribution system, and those Local Distribution Companies who are embedded in Hydro One Networks’ distribution system.
If the distribution portion of the application is approved as filed, in addition to the transmission charges, approximately 60% of residential customers would see the typical monthly bill impacts below, which include the Distribution Rate Protection (DRP) Program. The DRP Program is funded by the provincial government to keep the delivery charges more affordable for year round medium and low density residential customers.
| Customer Class | 2028 | 2029 | 2030 | 2031 | 2032 |
| Residential Medium Density (750 kWh) | ($0.10) | $0.00 | $0.00 | $0.00 | $0.00 |
| Residential Low Density (750 kWh) | ($0.21) | $0.00 | $0.00 | $0.00 | $0.00 |
For a typical residential urban density and a typical general service customer (GSe) of Hydro One Networks, if the application is approved, they would see the following monthly changes that are in addition to the transmission changes:
| Customer Class | 2028 | 2029 | 2030 | 2031 | 2032 |
| Residential Urban Density (750 kW) | $10.98 | $5.88 | $4.62 | $2.17 | $2.27 |
| General Service less than 50 kW (2,000 kWh) | $49.39 | $26.34 | $20.40 | $8.44 | $8.89 |

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).
