How Should Ontario Set Uniform Electricity Transmission Rates? (Phase 2)
Official title: Generic Hearing on Uniform Transmission Rates - Phase 2
The Ontario Energy Board is reviewing how electricity transmission costs are shared across the province. This technical proceeding examines whether the current 'uniform transmission rate' system is fair to all ratepayers. A decision and rate order was issued in November 2025, with a working group now addressing implementation details.
Why This Matters
Pay an electricity bill in Ontario? This affects you. Transmission costs are part of what you pay every month. The OEB is deciding whether large industrial users and residential customers should share these costs differently. Changes could shift costs between customer classes.
What Could Change
The OEB has already issued decisions on several issues and a rate order in November 2025. A working group is now developing implementation details. Changes to how transmission costs are allocated could affect electricity bills for different customer classes across Ontario.
Key Issues
- How should transmission costs be allocated among different customer classes?
- How should the uniform transmission rate methodology be implemented?
- How should 'double peak' billing situations be handled?
