ATCO and Enforcement Staff Settlement Agreement on Customer Rate Class Switching Requests [Update]

In proceeding 27948, the Enforcement staff of the Alberta Utilities Commission (the Commission) request an enforcement proceeding and approval of a settlement agreement between the Enforcement staff and ATCO Gas and Pipelines Ltd. (ATCO). The investigation behind the agreement was in response to a complaint from TCB Welding & Construction Ltd. (TCB) concerning high-use delivery service charges. TCB alleged that ATCO delayed switching it from the mid-use to the high-use delivery service rate and TCB was overcharged from December 2020 to November 2021.[1]

The Contraventions

After their investigation, Enforcement staff found that ATCO failed:

  • To make TCB aware of ATCOs rate schedules for different customer rate classes.
  • To apply the most favourable rate schedule to TCB in a timely fashion.
  • To refund the difference in rates charged to TCB between when it requested an alternative rate and when ATCO updated TCB’s rate class.[2]
