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.

- For OEB's other lines of effort to ensure efficient integration of EVs with the electricity system, please visit Electric Vehicle Integration (EVI).

OEB invites stakeholders to complete survey about sharing distribution system capacity information
Today, a survey has been posted about distribution system capacity information. The purpose of this survey is to gather insights from distributors, electric vehicle charging service providers and other interested stakeholders regarding the potential benefits and mechanisms for providing publicly available capacity information about the distribution system, in alignment with the Letter of Direction we received from the Minister of Energy. Your input will assist the DER Connections Review Working Group in discussions to develop an approach to distributors providing system capacity information.
Please click here to participate in the survey.
We encourage you to complete the survey by April 5, 2024. Please ensure only one survey is completed by your organization. All individual responses will be kept confidential. Aggregated data by industry sector will be provided to the DER Connections Review Working Group and may be included in any future reporting on this initiative.
