Distributed Energy Resources (DER) Connections Review

The OEB is currently reviewing issues related to DER connections and EV charging connections.


The OEB initiated a review of the requirements for the connection of DERs by licensed electricity distributors in 2019. The DER Connections Review focused on addressing any barriers to the connection of DERs, and where appropriate, how to standardize and improve the connection process. The OEB established the DER Connections Working Group made up of distributors, transmitters, DER providers and consumer groups to provide advice and recommendations. During the last 3 years a series of changes have been made to streamline the process of connecting DERs.

We are now commencing the next stage (i.e., Tranche 5) of the initiative which will focus on enabling higher DER penetration through exploring different approaches to address local capacity issues and clarifying cost responsibilities for DER connections. At this stage, we are also reviewing issues related to electric vehicle (EV) charging connections such as information sharing, connection process, technical requirements and cost responsibility.

  • OEB issues letter making changes to Appendix C of the Distributed Energy Resources Connection Procedures (DERCP)

    The OEB is making changes to Appendix C of the DERCP as part of its ongoing DER Connections Review initiative. These changes will come into effect on September 18, 2023. The new information in the Appendix C will offer customers, who consider applying to connect a DER to a distribution system (i.e., applicants), valuable insights into potential connection complexities and risks related to available capacity, project costs and timelines. This additional information will enable customers to make more informed decisions before proceeding with formal connection requests.

    For further details, see the OEB letter along with the new template forms and examples below.


    If you have any questions or concerns regarding the Distribution System Code, DERCP or the new forms, please contact IndustryRelations@oeb.ca.

  • Updated Distribution System Code

    The OEB has published an updated Distribution System Code that incorporates amendments aimed at enhancing clarity and consistency in the DER connection process. These amendments have come into effect today, June 7, 2023.

  • Amendments to the OEB's Reporting and Record-keeping Requirements

    Today, the OEB is making changes to the Reporting and Record-keeping Requirements (RRR) for electricity distributors as part of its ongoing DER Connections Review initiative. These RRR amendments will provide insight into the progress of Ontario’s energy transition.

  • Notice of Amendments to the Distribution System Code

    Today, the OEB has issued the final Notice of Amendments to the Distribution System Code regarding the connection of DERs to local electricity distribution systems. The amendments are intended to provide further clarity and consistency in the process for connecting DERs. These amendments come into force on June 7, 2023.
