Rates & Regulatory

Electricity delivery is a fully regulated service. That means the Alberta Utilities Commission (AUC) reviews our costs in detail and approves our rates to ensure all of our charges are fair and reasonable. The AUC also approves our Terms and Conditions, and our Code of Conduct Compliance Plans. 


We work around the clock to make sure the power is there when your home, farm or business needs it. The approved distribution tariffs we collect let us continue providing this service safely and reliably. Your cost for electricity delivery includes distribution tariffs and rate riders, which can change throughout the year.

REA tariffs apply to farm and acreage customers who are members of a Rural Electrification Association. The tariff is approved by the REA board on behalf of its members.

2024 Residential Rates

Electricity delivery rates have been approved, on an interim basis, by the Alberta Utilities Commission (AUC) for 2024. Here is what residential customers can expect, effective January 1, 2024:

  • Overall decrease of 5.2% of their current total bill (total bill includes distribution, transmission, rate riders, retail energy charges etc.).
    • What this means for you? Rate changes will impact customers differently, depending on their energy usage. A typical residential household that uses 600 kWh of electricity per month will see about a $14.07 decrease on their monthly bill. Since 2020, commodity prices (reflected in the retailer portion of the bill) have been a primary driver of bill increases for customers who are on the Regulated Rate Option (RRO) for retail energy.  
  • Effective January 1, 2024, ATCO distribution rates increased by 9.9% and transmission rates increased by 3.1%
    • Offsetting the increase in distribution and transmission rates are lower rate riders, mainly driven by the discontinuation of the 2021 Interim Rate Relief rider implemented during the pandemic and economic downturn (Rider J). A Rate Rider is a temporary credit or charge that may appear on utility bills. The AUC approves rate riders to enable firms to recover actual operational costs that are not included in the approved rates. Learn more about our rate riders further down in the Distribution Tariffs section.
