Alberta Energy Regulator or Alberta Utilities Commission? Who Regulates What

Energy Regulators: illustrated cover for a LawDB guide about Calgary, Alberta
McCarthy Tétrault’s Calgary office runs much of the firm’s national oil and gas practice, according to Chambers, and has been adding energy regulatory lawyers. This guide is our own general overview.

Energy projects in Alberta often need approvals from more than one regulator. The split follows what is being regulated, so it helps to know which body does what before planning a project timeline.

The Alberta Energy Regulator

The Alberta Energy Regulator (AER) regulates the development of energy resources in the province across their life cycle. That covers oil and gas wells, oil sands projects and pipelines that stay within Alberta, along with the rules on measurement, liability and reclamation.

The AER handles licence applications, transfers, compliance and enforcement for these activities.

The Alberta Utilities Commission

The Alberta Utilities Commission (AUC) regulates the province’s electricity and natural gas utilities. It reviews applications for power plants, substations and transmission lines, and it sets or approves utility rates that are regulated.

Large power and renewable projects therefore commonly involve the AUC rather than the AER.

Federal and other approvals

Pipelines that cross provincial or international borders fall under the federal Canada Energy Regulator. Projects may also need environmental assessment, municipal approvals, land agreements and Indigenous consultation.

Regulatory hearings can be lengthy and technical, and early planning with a lawyer who handles them regularly can avoid costly delays.
