Annual electricity data

Each year the Alberta Utilities Commission​ requests that all Alberta electricity generators and distributors submit annual electricity statistics. The annual data collected provides valuable information used for planning/forecasting purposes by the Alberta Department of Energy, allows the Alberta Energy Regulator to compile its annual ST-98 report on Alberta’s energy supply/demand outlook, and provides useful information to the AUC.

To preserve the confidentiality of individual unit generators, the data collected is being made available to the public on an aggregate basis and is available for download.

All data from 2010 and earlier was collected and compiled by the Alberta Energy Regulator and its predecessors and is not available on this website. Commencing with 2011 statistics, and for every year after, this responsibility now falls under the jurisdiction of the AUC​ based upon Section 8 of the Hydro and Electric Energy Regulation.

The data compiled in the above tables was collected from third party sources. Its accuracy and completeness has not been verified by the AUC.
