Transmission Connections Review

The OEB is undertaking a review of the connection-related sections of the Transmission Systems Code (TSC) to enhance the effectiveness of connection processes, procedures, and requirements.

The TSC sets out the minimum standards that an electricity transmitter must meet in designing, constructing, managing, and operating its transmission system. It also stipulates the requirements, standards, terms, and conditions of a transmitter’s obligations to connect consumers to the transmission system, including performance standards, technical requirements and expansions and connections.

The provincial government’s Powering Ontario’s Growth report states that electricity demand is expected to increase over the coming decades, driven by economic growth

The TSC sets out the minimum standards that an electricity transmitter must meet in designing, constructing, managing, and operating its transmission system. It also stipulates the requirements, standards, terms, and conditions of a transmitter’s obligations to connect consumers to the transmission system, including performance standards, technical requirements and expansions and connections.

The provincial government’s Powering Ontario’s Growth report states that electricity demand is expected to increase over the coming decades, driven by economic growth and increased electrification. The Electrification and Energy Transition Panel’s Ontario’s Clean Energy Opportunity report noted that a key factor in attracting investment and enabling economic growth is timely access to electricity. The panel emphasized the proactive build-out of transmission infrastructure and actively steering new investment to suitable sites that allow for timely and cost-effective connections.

As the connection of new loads and supply resources including energy storage increases, the OEB’s review serves to ensure that the regulatory rules associated with connections in the TSC facilitate and enable those connections.

Stakeholders, including electricity transmitters, distributors, generators, licensed storage companies and other interested parties, will be invited to contribute comments and feedback throughout this engagement, that will inform the OEB’s Transmission Connections Review.

The review may result in amendments to the TSC and potentially other guidance to the industry, if required.

  • Notes from First Working Group Meeting of Transmission Connections Review

    The first working group meeting of the Transmission Connections Review (TCR) took place on August 26, 2024. Formed by the OEB to seek stakeholder input on key issues related to connections-related sections in the Transmission System Code, the inaugural meeting focused on issues being related to cost allocation policies for new or modified connections. For more information, read the meeting notes summarizing feedback received by OEB staff from working group members.

  • OEB invites nominations for Transmission Connections Review Working Group

    The OEB has identified two streams of work as part of its Transmission Connections Review:

    • Stream One: Integrating resources
    • Stream Two: Reviewing cost allocation policies for new or modified connections

    To address these issues, we'll be forming a working group to discuss each stream. Working group discussions may result in issues being added to the established issues list.

    The OEB invites each group that provided comments upon commencement of this review to join the working group. Other stakeholders who wish to join the working group are also encouraged to submit nominations.

    Details on the call for nominations, including required information as part of the submission, can be found in the OEB's July 19, 2024 letter. Please note, the nomination deadline is July 31, 2024.


  • Next steps shared for Transmission Connections Review: OEB letter issued on July 19, 2024

    On July 19, 2024, the OEB shared an overview of the responses from stakeholders in connection with the Transmission Connections Review (TCR), specified the issues list that the review will consider, and put out the call for working group nominations.
