SALTLoad: Distribution Substation Electrical Load Dataset

The dataset consists of synchronized electrical measurements recorded at 5-minute intervals from six distribution feeders and is intended to support research in electrical load forecasting, anomaly detection, energy analytics, and data-driven power system applications.

For each feeder, the dataset includes three-phase voltage, three-phase current, active energy, reactive energy (import and export), apparent energy, and derived power factor measurements. The electrical measurements are integrated with hourly meteorological observations, including temperature, humidity, precipitation, wind speed, solar radiation, atmospheric pressure, and cloud cover, together with calendar-based annotations identifying weekdays, weekends, public holidays, and major festivals.
