    Micro- and Small Distributed Generation Reporting

    Within Alberta, electric distribution systems are operated by utility companies and are the portion of the electric system that operates at 25 kilovolts or less. These distribution systems are used to deliver electricity from the Alberta interconnected electric system to an end-use customer. A Distributed Energy Resource is any resource that is connected to and can supply energy to an electric distribution system. This includes distribution-connected generation resources and energy storage. This report focuses on distribution-connected generation resources that are smaller than 5,000 kW. These resources are typically connected to a distribution system at customer locations.

    Distribution-connected generation, if it qualifies, can be designated as micro-generation. For the purposes of this report, resources that are not designated as micro-generation will be referred to simply as distributed generation. These reports include a section containing a brief description of each class of generation. In addition, there is data on the number of sites and total installed capacity broken out by energy source.

    Note: In August 2022, it was identified that at least 1200 micro-generation sites had not been properly reported to the AESO. As a result, the number of micro-generation sites has been undercounted since November 2020, with the bulk of the missing sites having been installed during 2022. As of the end of December 2022, 1,432 of these sites, with a total capacity of 8.4 MW, have now been reported. Please see the datafile link on this page for the corrected monthly capacities.
