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

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 dataset 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 grid and PV data span three years, EV mobility logs cover February 2021 to January 2022. Battery telemetry and heat pump demand data are available for the final six to eight months of the observation period (mid-2021 to early 2022), enabling detailed whole-home analysis for that specific window.
