What's New

OEB.ca will be undergoing a scheduled update on Monday, October 19 from 5 p.m. to 6 p.m. EDT. During this time, you may experience temporary interruptions or reduced functionality across the website. We apologize for any inconvenience this may cause and appreciate your patience and understanding as we complete these improvements.

The OEB has released an updated variance settlement factor that is to be used by electricity distributors to calculate a one-time credit or charge for consumers who choose to stop purchasing electricity through the Regulated Price Plan. This factor is called the "Final RPP Variance Settlement Factor" and is updated on the OEB website monthly.

The OEB has issued a Notice of Proposal to amend the Transmission System Code (TSC) as part of its Reliability and Power Quality Review. The proposed amendments would enhance the reliability and power quality framework for electricity transmitters by clarifying transmitter obligations related to power quality and updating the power quality standards in the TSC. Stakeholders are invited to provide comments by November 9, 2026.
