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.
