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 will set Hydro One's transmission rates for 2026. This determines how much the company can charge utilities—costs that get passed on to your bill. The decision has already been issued, so rates are now set.
Key Issues
- What revenue should Hydro One be allowed to collect for transmission services in 2026?
- How should deferral and variance accounts be handled in the rate calculation?
