Distributed Energy Resources (DER) facilitate the empowerment of consumers, as well as the emergence of new flexibility services. Prosumers need to have a higher control over their production and consumption capabilities, and this can only be achieved through a direct control over the data being captured by a next generation of smart meters enabling the owner of the data to trade with it and access added value services by aggregators. Taking control over the ownership of energy data, leads to new opportunities for energy communities. Energy communities will not only be able to trade their aggregated production, but also their aggregated consumption and storage flexibility.
