On March 9, 2022, the AUC announced that it would commence a stakeholder consultation to review the standards of service for new home connections and associated maximum investment levels for 2023-2028.

The AUC is seeking input from individual organizations including land developers and home builders, municipalities, electric distribution wire owners (utilities) and consumer groups.

The scope of this consultation is for residential single-family homes in greenfield developments only. For brevity, we sometimes use the terms “new single family homes” and “new developments” within the consultation materials.

Key dates (subject to change)

April

  • Introductory meetings with individual stakeholders.
  • Initial stakeholder consultation meeting held on April 27, 2022.

May

  • First round of questions for stakeholders (targeted questions on existing utility and building development practices).

June

  • Working group discussions.
  • Stakeholder submissions due June 21, 2022 (conduit and amperage working group follow-up questions).

July

  • AUC staff review and analysis of stakeholder submissions
  • Clarification of submissions as needed (by request of AUC)

August

  • Commission to review the proposed changes and stakeholder comments and make a decision about MILs for 2023.
  • Decision on 2023 MILs provided by end of August.

September

  • If applicable, utilities incorporate 2023 MILs decision into their forthcoming 2023 Cost of Service compliance filing applications.

    Thank you for your participation in the AUC’s consultation regarding a review of distribution utility investment levels (MILs) for residential single-family homes in greenfield developments (Bulletin 2022-03).


    At this time, we are scheduling two working group sessions as part of this consultation. Follow up working group sessions may subsequently be scheduled.

    • June 7, 10 a.m. - noon: Working group to discuss conduit usage requirements, and potential MIL treatment.
    • June 10, 10 a.m. - noon: Working group to discuss amperage requirements, and potential MIL treatment.


    If you are interested in participating in either or both of these working groups, please let us know. Thank you to everyone who has already indicated interest in participating, we have already included you in our invitation list.


    In preparation for those working groups, please consider the following questions (for clarity, completed analysis on the below is not required for the working group sessions):

    Conduit Usage

    1. Under what scenarios is conduit most useful?
    2. Should it be included as part of the MIL? Please provide rationale, including cost-benefit analysis where available.
      • What is the incremental cost associated with the use of conduit?

    Target audience: Utilities plus any other stakeholders that have information on these items.

    Amperage


    1. What is your average (median and mean) cost for 100A servicing and 200A servicing for single family residential greenfield developments?
      • Please provide context on what is included in these calculations.
    2. What are the additional costs that would result from a change to a 200A service standard?
      • Please identify based on capital groupings from the 2023 cost of service filing.
    3. What is your assumed investment term and how is that incorporated into your calculation?
    4. What work and equipment is included in this cost estimate?
    5. How might a change in service size impact utility 2023 costs for customer growth?
      • What changes to upstream infrastructure (e.g., primary cable or transformers) would be required at initial installation of services to new developments?
      • What diversity factor does this assume?

    Target audience: Questions 1 & 4 are targeted to builders/developers and utilities. Remaining questions (2,3,5) are intended for utilities.

    If other stakeholders have estimates/studies on these questions, they are also welcome to table that information in the working group discussions.
