Proceeding 27388  Register

Proceeding status: scoping of the proceeding

Decision expected: To be determined

Watch an AUC hearing


In Alberta, four companies own and operate the province’s electric distribution system (ATCO Electric Ltd., Fortis Alberta Inc., ENMAX Power Corporation, and EPCOR Distribution & Transmission Inc.) and two for natural gas distribution (ATCO Gas and Pipelines Ltd., and Apex Utilities Inc.).

The AUC uses performance-based regulation when setting rates for these distribution utility companies to encourage efficiencies through providing incentives for reducing costs while at the same time safeguarding reliability of service. As a result, distribution utility rates are kept lower for customers than they may have been otherwise. The regulatory model reduces the regulatory burden of a traditional cost of service model involving scrutiny of numerous financial statements and promotes incentives for utility companies to become more cost-conscious and improve operational efficiencies.

In this proceeding, the AUC will aim to establish, modify, or add parameters of the third generation of performance-based regulation (PBR3) plans that will start in 2024 for Alberta distribution facility owners (DFOs) and will include the following issues:

  • Annual PBR rate adjustments
  • Price cap versus revenue-per-customer cap
  • I (inflation) factor
  • X (productivity) factor
  • Capital funding provisions
  • Earnings sharing mechanism and the need for an efficiency carry-over mechanism
  • Quantification and tracking of efficiencies

The list of issues and specific items under consideration are included in Exhibit 27388-X0046 in the AUC’s eFiling System.
