Overview

The AUC regulates Alberta’s investor-owned electric, gas, water utilities and certain municipally owned electric utilities to ensure that customers receive safe and reliable service at just and reasonable rates.

The AUC also regulates the routes, tolls and tariffs of energy transmission through utility pipelines and electric transmission and distribution lines. Companies who propose to construct or rebuild electric generation, transmission or distribution facilities in Alberta, must apply to the AUC for siting approval.

When reviewing the utility’s application, the AUC considers the social and environmental impacts, as well as any economic implications for the ratepayers.

Furthermore, the AUC also provides an adjudicative function for issues arising in Alberta’s electric and natural gas markets.

Below is a list of some of the companies regulated by the AUC. Please note that we are unable to provide a comprehensive list due to the non-traditional nature of some utility services (such as micro-generation) and the continuous changes to the utility industry. This list is provided to give the reader some background on the regulated utility services provided by the following companies and to provide examples of the activities that are regulated by the AUC.
