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.
