Electricity Load Diagrams for 315 Clients in Portugal, 2012-2014

Portuguese electricity consumption data recorded every 15 minutes between 2011 and 2014. The dataset contains load diagrams for 315 clients after preprocessing, with values reported in kW. It was uploaded to OpenML by Artur Trindade under a CC-BY-4.0 license.

Use Cases

• Short-term electricity load forecasting based on 15-minute interval consumption data.
• Analyzing client-level consumption patterns and anomalies over a multi-year period.
• Benchmarking multivariate time-series models using a real-world energy dataset.
• Studying the impact of daylight saving time changes on electricity demand patterns as described in the source notes.

Strengths

• Data has no missing values according to the original source description.
• Covers a multi-year period from 2011 to 2014 with a consistent 15-minute sampling frequency.
• Includes specific documentation on handling daylight saving time transitions and data format.

Limitations

• Row count and total file size are unknown, which may limit suitability assessment.
• Column-level documentation for the 315 client columns is absent; semantics must be inferred.
• Last update date is unknown; freshness unverified.
