Consultation on 2023 cost-of-service review

Consultation on 2023 cost-of-service review

The AUC completed​​ a streamlined proceeding to determine the process of establishing 2023 rates for electric and natural gas distribution facility owners




In this proceeding, the Alberta Utilities Commission set out how it will process the 2023 cost-of-service (COS) applications that will be filed by the electric and gas distribution facility owners (DFOs or utilities).

Outlined in Decision 26354-D01-2021, the AUC has prescribed the minimum level of detail each application is expected to include to support the utilities’ 2023 revenue requirement forecasts, but will not prescribe a specific methodology for developing their 2023 revenue requirement forecasts. Instead, the AUC will adopt a hybrid methodology for assessing the 2023 forecasts where the extent to which expenditures are examined is guided by the nature, size or complexity of the associated cost to facilitate a streamlined review of the upcoming 2023 COS applications. The AUC also prescribes filing dates for these applications. This decision provides the AUC’s reasons for these determinations​.

As outlined in Bulletin 2021-04, ​the AUC​​, the independent utilities regulator, determined to proceed with a one-year cost-of-service review based on 2023 forecast costs. To minimize regulatory burden associated with undertaking a cost-of-service review of six distribution facility owners (DFO) applications, the AUC looked to employ alternatives to a traditional line-by-line review of utilities' forecast costs and provided several options to parties for consideration to facilitate a more streamlined review. To this end, the AUC​ initiated a streamlined proceeding to determine the process of establishing 2023 rates for electric and natural gas DFOs; namely

  • Apex Utilities Inc. 
  • ATCO Electric Ltd. (distribution)​
  • ATCO Gas and Pipelines Ltd. (distribution)
  • ENMAX Power Corporation (distribution)
  • EPCOR Distribution & Transmission Inc. (distribution)
  • FortisAlberta Inc.​​


As outlined in its notice of application, the AUC​ has established the following ​schedule and process to conduct this proceeding:​​
