Directions for Fortis’s Streetlight Investment

In Proceeding 27682, the Alberta Utilities Commission (the Commission) issues its decision regarding the terms and conditions (T&Cs) of FortisAlberta Inc. (Fortis) that pertain to its streetlight investment. In December 2021, Fortis sought the Commission’s input to determine whether Fortis should pay its streetlight investment to the developer or the municipality if the parties cannot agree on who is entitled to the payment. In Decision 27067-D01-2022, the Commission directed that the streetlight investment be paid to the municipality if the developer and municipality are in dispute. The Commission further directed Fortis to clarify the streetlight investment entitlement in its T&Cs.[1]

Fortis made its compliance filing. However, the Commission found that Fortis only complied with one of the three directions. Nevertheless, the Commission does not require Fortis to submit another compliance filing because the Commission will hear issues concerning streetlight investment in Proceeding 27658.[2]

Residential Standards of Service and Maximum Investment Levels (MILs) Proceeding Issues List

In Proceeding 27658, the Alberta Utilities Commission (the Commission) finalizes the issues list for addressing standards of service and maximum investment levels for residential services.

(ATCO), EPCOR Distribution & Transmission Inc., ENMAX Power Corporation, FortisAlberta Inc., the Alberta Federation of Rural Electrification Associations, the Office of the Utilities Consumer Advocate, and Melcor Developments Ltd. The Commission developed the following list based on these submissions.[1]

Issues List Summary[2]

  • The goal of setting MILs.
  • Whether MILs should be eliminated.
  • If MILs are not eliminated, determining the types of costs that should be eligible for MILs.
  • Deciding whether the prior MILs principles referenced in Decision 2010-309 are relevant and result in reasonable rates.
  • The scope of work that developers expect completed in exchange for MILs.
  • The electrical infrastructure the developer or homeowner is responsible for installing.
  • The average cost of providing electrical service to new greenfield residential developments.
  • The proportion of new connection costs to be recovered through MILs.
  • The developer and distribution facility owner (DFO) costs for consideration in MILs.
  • The timing of a utility investing in new residential services (i.e., once the infrastructure is in place, or when an end-use customer has bought a home and has enrolled with a utility service?).

2024 GCOC Evidence

In proceeding 27084, intervenors submit their evidence regarding the issues list and other matters put forward by the Alberta Utilities Commission (the Commission) concerning the 2024 Generic Cost of Capital (GCOC). The Commission decided that the equity risk premium (ERP) approach for determining return on equity (ROE) is appropriate. The ERP approach is the basis for the one-factor formula previously approved by the Commission in 2009 and the two-factor formula adopted by the Ontario Energy Board (OEB). The Commission produced an issues list based on the two-factor approach, which the following formula expresses:

  • ROE (test year) = Notional ROE (VAR1 + VAR3) + Factor One + Factor Two
  • Factor One = VAR4 x (Forecast Long Canada Bond Yield (test year) (VAR2) – Base Forecast Long Canada Bond Yield (VAR1))
  • Factor Two = VAR7 x (Utility Bond Spread (test year) (VAR6) – Base Utility Bond Spread (VAR5))

The Commission’s questions in the issues list mainly ask intervenors to calculate and justify appropriate variables (VAR) for the above equation.

2023 Maximum Investment Levels Decision

In Proceeding 27658, the Alberta Utilities Commission (the Commission) sets the maximum investment levels (MILs) for 2023 that a distribution facility owner (DFO) can contribute to the cost of connecting a new customer to its system. Therefore, the 2023 MILs for each DFO will be set by escalating the 2022 MILs by a 2.68 percent inflation factor.[1]

2023 Maximum Investment Levels (MILs)

Individual developers are responsible for constructing electric utility infrastructure inside new residential developments within FortisAlberta Inc., ATCO Electric Ltd., and EPCOR Distribution & Transmission Inc. (the DFOs) service areas. After completing construction, the developer passes infrastructure ownership back to the DFO and receives compensation from the DFO according to the approved MILs. Any costs beyond the MILs fall to the developer.[2]
