Abstract

Increasing distributed renewable energy generation renders balancing of energy supply and demand more challenging. Peer-to-peer (P2P) exchange of decentrally generated energy is a promising means to optimize renewable energy flows. While previous research has primarily focused on the technological and economic benefits of P2P energy trading, little research has investigated customer preferences in this context so far. It is thus still unclear to what extent private actors such as homeowners are actually willing to participate in P2P energy communities and if so, under which conditions. Here, we address this research gap by analyzing homeowners' trading decisions in simulated P2P electricity trading scenarios. Findings based on a sample of 301 German homeowners show that community electricity prices and state of charge of private energy storages are key determinants of homeowners' trading behavior. We moreover identified four target groups that systematically differed in their decision-making strategies ranging from price-focused prosumers (38.9%) to classic nontrading consumers (22.6%). Our findings provide promising insights for the design of P2P communities and allow policy makers to more accurately predict risks and benefits associated with P2P projects. Finally, our findings contribute to the development of tailored policy instruments aiming to increase P2P trading in decentralized energy communities.
