Abstract
"Open-access domestic electricity dataset from 5 UK homes with whole-house demand at 16 kHz and appliance channels at 6-second intervals. Research-paper dataset release. Used for NILM, load disaggregation, and smart-meter analytics."
Description
Overview
UK-DALE is a landmark open-access dataset for domestic electricity demand recorded in five UK households. It combines high-frequency whole-house measurements with appliance-level signals, enabling detailed studies of residential consumption patterns.
The dataset was designed to support energy disaggregation and consumer-feedback research in the context of smart metering. One of the homes was monitored for 655 days, making the release unusually long for an appliance-level public benchmark.
Column Schema
| Column | Description |
|---|---|
| timestamp | Time of observation. |
| aggregate_power | Whole-house apparent or active power demand. |
| appliance_power | Power draw for an individual monitored appliance. |
| voltage | Whole-house voltage signal where available. |
| current | Whole-house current signal where available. |
| house_id | Identifier for the monitored residence. |
| channel_id | Appliance or circuit channel identifier. |
