The OEB has issued a letter setting out the requirements for licensed distributors to provide standardized available distributed energy resource (DER) hosting capacity data for inclusion in the Centralized Capacity Information Map (CCIM). The CCIM with both DER hosting and load customer capacity information will launch in December 2025. It is expected to help customers, developers and planners identify where new generation facilities can connect and support more informed discussions with distributors about connection feasibility.
On September 16, 2025, the Distribution System Code (DSC) amendments establishing a Capacity Allocation Model (CAM) to facilitate electricity system expansions in support of housing development came into force. In response to stakeholder feedback received during the consultation process, the OEB has issued a letter setting out its expectations and guidance to support the CAM implementation, including record-keeping and accounting.
The OEB is sharing template opt-in forms, a record-keeping template and communication materials to support electricity distributors implementing the Electric Vehicle (EV) Charging Rate, which aims to support the efficient integration of EVs in Ontario.
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 published the 2025 Quarter 4 prescribed accounting interest rates applicable to the carrying charges of deferral, variance and construction work in progress (CWIP) accounts of natural gas utilities, electricity distributors and other rate-regulated entities.

The OEB has updated its Open Data files with 2024 Reporting and Record-keeping Requirement (RRR) data, including updates to the newer electricity transmitter data that was added last year. Data integrity and consistency have been improved across all categories, covering both 2024 and earlier years. Four interactive Dashboards have also been refreshed with 2024 RRR data. These dashboards provide comprehensive insights on industry trends, distributor performance, and allow for customized data visualization and convenient performance comparisons.
The OEB is initiating a review of regional and bulk electricity system planning processes that are more efficient, flexible and responsive to better match the demand needs of Ontario. To support this review, an Advisory Group is being established to explore opportunities to enhance the planning process. Letters of interest from stakeholders to the OEB about participating in this advisory group should be emailed to registrar@oeb.ca by September 12, 2025.
Read the OEB’s letter for details on the advisory group’s scope and timelines, including instructions on submitting a letter of interest.
