Residential Energy Dataset with Electric Vehicles, Photovoltaic Generation and Tariff Variability in Ireland

Abstract Household energy demand data are essential for designing load-shifting strategies, storage solutions and demand response programs. This is the first publicly available dataset that integrates multiple household-level energy and mobility metrics. These include grid imports and exports (30-minute intervals), rooftop photovoltaic (PV) production (30-minute intervals), EV charging sessions, and detailed journey logs (start time, end time, distance, and duration) from the same households of a pilot energy community located on the Dingle Peninsula, Ireland. The subset includes four volunteer households, each equipped with a 2.1~kWp rooftop PV system, 5~kWh Sonnen battery, a Hyundai Kona Electric (64~kWh), a Pulsar Plus EV charger (7.4~kW AC), and a Mitsubishi Electric Ecodan air-source heat pump. While heat pumps and batteries were installed in all participating households, their data were excluded from this release due to inconsistent logging across sites. Data coverage spans from early 2019 to early 2022 for grid imports, PV production, and tariffs, and from February 2021 to January 2022 for EV journeys and charging session.
