Portuguese Electricity Load Diagrams: Hourly Client Consumption from 2012 to 2014

319 columns represent individual client electricity consumption in kW, resampled to hourly intervals. The dataset covers load diagrams from Portugal between 2011 and 2014, with preprocessing steps detailed by author Artur Trindade. It is licensed under CC-BY-4.0 and sourced from the OpenML platform.

Use Cases

• Forecasting short-term electricity load for individual clients based on hourly consumption patterns.
• Analyzing the impact of daylight saving time changes on energy demand, as described for March and October.
• Modeling client-specific energy usage behavior across a multi-year time series.
• Benchmarking multivariate time series models using a dataset with over 300 concurrent series.

Strengths

• Contains 319 columns of client-specific consumption data, providing a multivariate view.
• Explicitly states it has no missing values in the original source data.
• Covers a multi-year period from 2011 to 2014 with hourly granularity.
• Preprocessing steps, including the removal of 54 columns with over 10% zero entries, are documented.

Limitations

• Row count is unknown, which may limit suitability assessment for model training.
• Column-level documentation for the 'value_X' fields is absent; client semantics must be inferred.
• Last update date is unknown; freshness unverified.
