The Open Data

By providing you with real yearly, monthly and daily energy data for one of the largest level residential areas in Västerås, Sweden. We are eager to see how your innovative approaches can make our daily energy usage more sustainable and efficient with for example novel analytical methods, visualization techniques and/or maybe combining our data with other relevant data.


The data that we make public origins from the years 2019 and 2020, and represents both the electricity and district heating usage, sometimes also fresh water usage, of buildings and households in the selected area. The data are aggregated into smaller groups with consists at least of five households in order to not reveal any sensitive behavioural information of individual users, but play with the idea that still future services and solutions could be given directly to individual households!


Your solutions should contribute to some value in terms of economic, environmental or social sustainability for the individual households, energy utilities, cities and/or to the society as a whole!
