The dataset, Canadian Open-source Database for Energy Research and Systems-Modelling (CODERS) leverages the existing national and provincial databases made public by utilities, system operators, independent power producers, regulators, government agencies and energy associations. Data contained in CODERS relates to generation facilities, transmission networks, substations and other system assets, as well as to system operations, demand, forecasts, imports, exports and costs.

The CODERS database houses data collected by the Sustainable Energy Systems Integration and Transitions (SESIT) group. This data is integral to populating our comprehensive suite of energy systems models, which encompass various vectors (such as power, transport, and building) and scales (including municipal, provincial, and federal levels), as well as sectors (like electricity, heat, and water). Currently, the database is maintained and regularly updated by the Energy Modelling Hub.
