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.
