In early January of each year, a request is sent out to all Alberta electricity generators and distributors to submit electricity statistics. Up until 2010, predecessors to the Alberta Energy Regulator sent out these requests. Commencing with 2011 statistics, and for every year hereafter, this responsibility now falls under the jurisdiction of the Alberta Utilities Commission. The AUC has the authority to collect such data based upon Section 8 of the Hydro and Electric Energy Regulation (Alberta Regulation 409/1983).

The annual data collected provides valuable information that is used for planning/forecasting purposes by the Alberta Department of Energy, it allows the AER to compile its annual ST-98 report on Alberta’s energy supply/demand outlook and it provides useful information to the Commission.

To preserve the confidentiality of individual unit generators, the data collected is being made available to the public on an aggregate basis only. The aggregated data is available for download in .pdf or .xls format by clicking on the hyperlink below the corresponding table name:
