Prosumers in many regions are facing reduced feed-in tariffs and currently\nhave no possibility to influence the level of remuneration for the locally\nproduced solar energy. Peer-to-peer communities may offer an alternative to the\nfeed-in tariff model by enabling prosumers to directly sell their solar energy\nto local consumers (possibly at a rate that is beneficial for both consumer and\nprosumer). The Quartierstrom project investigates a transactional energy system\nthat manages the exchange and remuneration of electricity between consumers,\nprosumers and the local electric grid provider in the absence of\nintermediaries. This whitepaper describes the prototypical real-world system\nbeing implemented in the town of Walenstadt, Switzerland, with 37 participating\nhouseholds. The community members of this pilot project pay a reduced tariff\nfor grid usage if the electricity produced by a prosumer is sold to another\ncommunity member, which is located on the same voltage or grid level downstream\na substation1. Such a tariff structure incentivizes local balancing, i.e.\nlocally produced energy can be consumed locally whenever possible to avoid\ncosts from higher grid levels. The blockchain is a novel technology suitable to\nlog the produced and consumed units of energy within a community, making it\npossible to implement market places. In those marketplaces, both prosumers and\nconsumers can indicate a price at which they are willing to sell / buy locally\nproduced solar energy without the intermediation of a utility. The key goals of\nthis project are the assessment of A) the technical, economical and ecological\nfeasibility of a blockchain-based community energy system regarding local\nutilization of solar energy, grid quality and energy efficiency and B)\nresulting dynamics regarding local market prices and user acceptance.\n
