【Abstract】The continued proliferation of renewable energy sources (RES) in the residential sector enables private households to increasingly participate in the energy market. However, it also poses an infrastructural challenge as their spatial dispersion and the simultaneity of their energy generation increase the strain on the main grid. Local energy markets (LEMs) have been proposed to amend this effect by leveraging market dynamics to efficiently allocate privately generated energy in the immediate vicinity. Blockchain has been suggested as suitable information technology to reflect and support the decentralization and the parity characteristic of such LEMs. While some research on the topic has been conducted, concerns regarding anonymity in the proposed markets remain. In this study, we hence conceptualize a Blockchain-based LEM which expands on previous designs by introducing a one-time-address-based anonymization technique. The proposed concept also extends the double auction mechanisms of existing LEMs by a sealed offering protocol, providing information symmetry. The concept is prototypically implemented and validated using a Proof of Authority Ethereum network. It is shown that the implementation is sufficiently scalable for proposed LEM sizes.
