Hydro One 2026 Transmission Revenue Requirement (EB-2025-0159)
Official title: 2026 electricity transmission revenue requirement annual update
Hydro One is asking the Ontario Energy Board to approve how much money it can collect from electricity customers in 2026 to maintain and operate the province's transmission grid. This is an annual update under an incentive-based rate framework. The OEB has already issued a decision and order on this application.
Why This Matters
Pay an electricity bill in Ontario? Part of what you pay goes to Hydro One for moving power across the province. This decision affects that portion of your bill. While individual impacts are small, transmission costs add up across millions of customers.
What Could Change
The OEB has approved Hydro One's 2026 transmission revenue requirement. This sets how much the company can charge for moving electricity across Ontario's high-voltage grid. The approved rates will appear on electricity bills starting in 2026.
Key Issues
- What revenue should Hydro One be allowed to collect for transmission services in 2026?
- Are the proposed charge determinants and rate pools appropriate?
How to Participate
- Review the Decision and Order to see the OEB's ruling on this application.
- Review the Notice for information about the proceeding and how to participate in future OEB cases.
What Happened
The Ontario Energy Board issued a Decision and Order on October 7, 2025, concluding this proceeding.
