Ontario Power Generation Filing Guidelines Review

The Ontario Energy Board (OEB) has initiated a consultation to review a proposed update to the OEB’s Filing Guidelines for Ontario Power Generation (OPG) based on the current legislative and OEB policy frameworks and general practices.

The Filing Guidelines outline filing expectations for OPG on payment amounts applications and related matters under Section 78.1 of the Ontario Energy Board Act, 1998 (the Act). The OEB expects that OPG will file its next payment amounts application in 2025.

There have been no changes to the Filing Guidelines since they were developed in 2011 and based on feedback from various stakeholders over the years, they have served their purpose reasonably well.

The purpose of this engagement is to work with stakeholders to determine what, if any, updates are needed to:

  • account for the passage of time
  • reflect learnings from OPG’s payment amounts proceedings since 2011
  • incorporate further efficiencies in relation to the regulatory process
The OEB is also considering changing the name of this resource, i.e., from “Filing Guidelines” to “Filing Requirements,” in alignment with current practice for other application types.

  • OEB issues updated Filing Requirements for OPG's payment amounts applications

    Today, the OEB has issued updated Filing Requirements for OPG’s payment amounts applications. These updates include revisions to the 2011 guidelines, informed by stakeholder comments and discussions. The Filing Requirements aim to address the evolving regulatory landscape, incorporate lessons learned from past proceedings, and remain evergreen.

    The draft update released by OEB staff on April 23, 2024, for stakeholder comment did not propose wholesale changes but rather more targeted revisions. These include:

    • Aligning language and terminology for consistency with other OEB filing requirements
    • Revising exhibit titles
    • Removing references to specific years and specific facilities
    • Renaming the Filing Guidelines to Filing Requirements

    The above changes elicited broad support from stakeholders and have been incorporated into the updated Filing Requirements.

    Other notable changes to the Filing Requirements include:

    • Updated cost thresholds for capital projects: These thresholds better reflect inflationary increases and enhance regulatory efficiency by focusing on more substantial projects while ensuring that evidence is available for a comprehensive review. Tier 1 Capital Projects are now set at $30 million, with corresponding adjustments to Tier 2 and 3 cost thresholds.
    • Term-over-term variance analysis: This will replace year-over-year variance analysis for capital costs and project operating, maintenance, and administration costs (OM&A). However, OPG is still required to provide a year-over-year variance analysis for base OM&A costs.
    • Historical Years: To ensure that the application evidence focuses on the most relevant data, the updated Filing Requirements require OPG to provide the five most recent historic years. If OPG is unable to provide certain historical data, it should clearly set out the reasons for this. Specific guidance has also been provided in the cover letter for the historical data applicable to the next OPG hydroelectric application.
    • Capitalization policies: The final Filing Requirements include the requirement for OPG to file a plan for transitioning away from capitalizing indirect overheads or provide a justification for maintaining its current practice. (At this time, OPG is required by regulation to do its financial reporting under United States Generally Accepted Accounting Principles.)


    The OEB extends its gratitude to all stakeholders who participated in the consultation process.

  • About the OEB's Filing Guidelines for Ontario Power Generation

    OPG is the province’s largest electricity producer – its regulated generation facilities in Ontario consist of the Darlington Nuclear Generating Station and the Pickering Nuclear Generating Station and 54 regulated hydroelectric generating stations.

    OPG’s payment amounts relate to generation from its nuclear and hydroelectric facilities. OPG’s payment amounts make up a portion of the electricity line, one of the line items on customers’ bills.

    The OEB is authorized to set these payment amounts under Section 78.1 of the Ontario Energy Board Act, 1998. The form, methodology, assumptions and calculations to be used in determining these amounts, along with the rules that must by followed by the OEB are set out in O. Reg. 53/05.

    The OEB publishes Filing Guidelines for OPG that are intended to establish regulatory predictability and assist OPG in ensuring that its payment amounts applications include the information the OEB needs. The Filing Guidelines also include the rules the OEB must follow in setting those payment amounts.
