About Open Power System Data

Open Power System Data is a free-of-charge data platform for electricity system researchers. It collects, checks, processes, documents, and publishes publicly available power system data that is inconvenient to use, aiming to help modelers avoid redundant data preparation and improve data quality and documentation.

The platform covers installed generation capacity by country and technology, individual conventional and renewable power plants, and time series such as electricity consumption, spot prices, and wind and solar generation, including measured data and values derived from weather models. Data are published primarily as CSV files with JSON metadata, plus Excel and SQLite files, and processing scripts are open source under MIT on GitHub. Some data may be subject to copyright because not all data owners allow publication under a Creative Commons Attribution license, and the project is aimed primarily at energy professionals rather than the general public or real-time monitoring.

Key features

  • Installed generation capacity by country and technology
  • Individual conventional and renewable power plant records
  • Time series for electricity consumption, spot prices, and wind/solar generation
  • Measured generation data and weather-model-derived values
  • CSV data, JSON metadata, plus Excel and SQLite files
  • Version-controlled scripts and data with stable URLs
Best for: Power system modelers and analysts in academia, consulting firms, and industry who need documented historical electricity data.
Good for
  • Free-of-charge platform intended to reduce redundant data collection for researchers.
  • Aims to provide clearly structured, documented, internally consistent, and accessible data.
  • Processing scripts are open source under MIT, and data/scripts are version-controlled for reproducibility.
Watch out for
  • Some published data may be subject to copyright; not all data owners allow Creative Commons Attribution licensing.
  • Not primarily intended for journalists, the general public, or electricity traders.
  • Focuses on long historical time series rather than high-frequency real-time updates, and provides CSV files rather than visualizations.

Open Power System Data FAQ

Who is the platform intended for?
Energy professionals such as modelers and analysts in academia, consulting firms, and industry. Journalists, the general public, and electricity traders are not primary target groups.
What types of data are available?
Installed generation capacity by country and technology, individual conventional and renewable power plants, and time series for electricity consumption, spot prices, and wind and solar generation, including measured and weather-model-derived data.
Can all data be used without restriction?
The project aims to publish all data free of charge under a Creative Commons Attribution license, including for commercial applications, but several data owners do not allow this and some published data might be subject to copyright.
