Electric Vehicle Integration

This initiative is intended to inform actions the OEB may take to ensure the efficient integration of electric vehicles (EVs) with the electricity system.


Delivery Rates

As part of the Electric Vehicle Integration (EVI) initiative, the OEB completed an analysis of the impact delivery costs have on EV charging service providers and owners of EV fleets. Alternative delivery rate designs are being explored to determine how they may support EV adoption while adhering to sound ratemaking principles.

Distributed Energy Resources (DER) Connections Review

Issues related to EV connection processes & requirements and system readiness are being reviewed through the DER Connections Review subgroup on EV Charging Connections.

Ultra-Low Overnight (ULO) Price Plan

This new price plan supports shifting electricity use to overnight when provincewide electricity demand is lower, supporting the integration of EVs.

  • OEB Letter on System Investments for Electric Vehicle Integration

    The OEB has issued a letter summarizing recent guidance and resources to help electricity distributors in planning their systems for the efficient integration of electric vehicles (EVs). The letter also informs the sector of an expansion of scope to the Distributed Energy Resources Connections Review consultation to review matters relating to system readiness for EV charger connections.

  • Residential Customer Connections & Service Upgrades Bulletin

    The OEB has issued a Bulletin providing guidance to distributors regarding residential customer connections to support electric vehicle adoption and electrification. The Bulletin also reminds distributors of their obligations under the Distribution System Code (DSC) in relation to residential subdivision connections and service upgrades.

  • Delivery Rates Report

    The OEB has released a consultant report that examines electricity delivery rates for commercial EV charging and explores alternative rate design options that could support the efficient integration of EVs in Ontario.

    The report focuses on electricity delivery rates applicable to commercial EV fleets (e.g., public transportation, delivery trucks, etc.) and public EV fast charging stations.

    Stakeholders interested in participating and providing feedback on this report are invited to a meeting on May 24, 2023. See the OEB letter below for further details on how to participate. The OEB recognizes that this topic is of interest to many parties, and therefore welcomes feedback from a broad cross-section of industry stakeholders, whether or not they are directly involved with EVs.


    [Update on May 17, 2023]: To support the May 24th meeting, additional materials were developed for the session:


    [Update on May 31, 2023]: In response to a stakeholder request, the OEB issued a letter extending the due date for written feedback on the report to June 14, 2023.



  • Report on EV Survey

    As part of its first line of effort, the OEB procured a consultant that completed a survey of local distribution companies and EV charging service providers in late 2022, and produced a “what we heard” report on January 27, 2023.

    The report provides insight from the survey respondents on system readiness, delivery costs, and connections and will inform next steps in relation to EV integration.

    The OEB cover letter and the consultant report are available through the links below:

  • EV Stakeholders Invited to Participate in the DER Connections Review

    As part of the OEB’s Distributed Energy Resources (DER) Connections Review, Tranche 5 of the DER Connections Review will begin in late January 2023 and include ongoing consideration of issues related to EV connections.

    EV stakeholders interested in participating and providing feedback to the OEB for this area of focus are invited to contact the DER Connections Review Team at DER.ConnectionsReview@oeb.ca.

  • OEB moving forward with a survey of Electricity Distributors and EV Charging Station Service Providers

    In late November, the OEB plans to launch a survey of electricity distributors and EV charging station service providers. If you are an EV charging station service provider that has not yet been contacted for inclusion in this survey, please email EVintegration@oeb.ca by November 18th, 2022, so that your contact information can be shared with Guidehouse, the consultant engaged to complete this survey.

    Electricity distributors will be contacted through their Regulatory Affairs contact.
