Abstract Buildings consume on average of over 40% of energy throughout the world[ 1]. Therefore, it is crucial to fully understand the consump- tion behaviour of building occupants for energy efficiency, efficient load balancing and better demand-side management. To this end, small number of datasets are available from developing countries, particularly South Asia, that can model consumption behaviours of a wide range of residential electricity users. In this paper, we present PRECON dataset, collected over a period of one year, of electricity consumption patterns for 42 residential properties having varied demographics. Data is collected for the whole house con- sumption and from high powered devices as well as from major areas of the building. This dataset can play a pivotal role for distribu- tion companies and policymakers to use data-driven optimization of generation, perform better demand-side management and improve energy efficiency.
