SHEERM: Sustainable Household Energy and Environment Resources Management with Time-Series

Overview

SHEERM (Sustainable Household Energy and Environment Resources Management) is a real-world dataset presented in Nature Scientific Data that captures household-scale energy dynamics alongside environmental and market factors. It integrates household electrical consumption, on-premises solar energy production, weather conditions, and electricity pricing over a multi-year period.

Data Collection

• Thirteen Portuguese households equipped with certified smart electric meters recording consumption every 15 minutes.
• Collection period spans nearly three years of continuous measurements.
• Data sources include smart meters (household loads), PV systems (solar generation), nearby weather stations (temperature and irradiance), and electricity market data (hourly prices).

Measured Variables

• Household electrical load (kW), in raw and processed forms.
• Solar PV generation (kW) derived using photovoltaic modeling and validated against independent measurements.
• Weather parameters such as solar irradiance, ambient temperature, humidity, and wind.
• Electricity market price (e.g., EUR/kWh) for day-ahead and real-time markets.

Data Organization

• Four main partitions: load, price, weather, and PV generation.
• Load data provided as raw and processed time-series; processed data has missing values handled and outliers removed.
• All data streams are synchronized using timestamps, enabling multi-dimensional analysis.

Use Cases

• Short-term and long-term forecasting of household load and solar generation.
• Demand response and grid optimization studies.
• Cost minimization strategies based on dynamic electricity pricing.
• Analysis of renewable integration at the household level.
