The pilot peer-to-peer energy market “Quartierstrom” consists of 35 households and two businesses with 27 photovoltaic and 8 energy storage systems. It includes three key innovations: (1) A local electricity market that allows producers and consumers to monitor market developments, to find trading partners, and to adjust their prices. (2) A bottom-up electricity tariff: Locally produced electricity is favored by the fact that only the local costs of the grid (grid level 7) are included in the price of locally produced electricity. This is a major paradigm shift, for which the legal foundations still have to be developed (in collaboration with ElCom). (3) A blockchain-based platform designed for efficient transaction processing that does not require large amounts of energy. Overall, the project has not only elicited interest within the scientific community, but has initiated important discussions and impulses in politics, among regulators, and in the general public.
