The project

Open Power System Data develops a free-of-charge platform for open data dedicated to electricity system researchers. We collect, check, process, document, and publish data that are publicly available but currently inconvenient to use. The project is a service provider to the modeling community: a supplier of a public good. Learn more about its background or explore the data platform.


Primarily, we will provide information of installed generation capacity, power plants, and time series of electricity consumption and wind and solar generation. We have collected data from Germany and neighboring countries and extend the geographical scope step by step. We also gradually include more types of data, such as historical spot prices and weather data.

User-friendly data

We envision a central, user-friendly online platform. Our goal is a comprehensive set of power system data that are clearly structured, well documented, internally consistent, and easily accessible. The scripts used for downloading and processing are open-source and available through GitHub. We follow the Data Package convention and publish data as CSV files and metadata as JSON files (XSLX and SQLITE files are also available). Read more about our decentralized IT approach.

Open data

Currently, energy data is often subject to quite restrictive terms of use (examples). We try to do better: the scripts that we use to process data are open source and available under the MIT license on GitHub. The text on this website is published under CC-BY. It is our goal to provide all data on this platform free of charge to anyone without restriction on its use, including commercial applications. We would like to publish all data under a Creative Commons Attribution license, an open license that allows any use and derivative work. However, at this point, several data owners would not let us do so. Beware that some data might be subject to copyright. In addition, we support the position of the Free Software Foundation Europe for free Software and Open Standards in Horizon 2020 and all publicly-funded research.

An award-winning platform

Open Power System Data is the winner of the Open Science Award Schleswig-Holstein 2017.

The target group

This platform is made for energy professionals such as modelers and analysts in academia, consulting firms, and industry. Journalists, the general public, and electricity traders are not our primary target groups. We provide boring CSV files rather than fancy visualization. We will also update data only a few times a year, rather than providing real-time information.

Our objective

We want to make life easier for power system modelers. In concrete terms, our objective is three-fold:

  • Efficiency: avoid double work.
  • Quality: improve the quality of data and documentation.
  • Legal certainty: using a well-established open license.

The team

Open Power System Data is implemented by four institutions: Europa-Universität FlensburgDIW Berlin, Technical University of Berlin, and Neon Neue Energieökonomik. It is funded by the German Federal Ministry for Economic Affairs and Energy.


The project runs from August 2015 to July 2017. We have published a list of data sources, a list of data projects, and an account of the legal situation in 2015. After a closed beta version was published in early 2016, in October 2016 the first public version of the data platform was published.

Get involved!

We want open data and an open process. We are involving data owners and future users of the platform in a series of workshops, webinars, and interviews. We will coordinate with various projects that follow similar goals, and with the Open Energy Modelling Initiative. Stay up to date by subscribing to our newsletter. If you would like to be involved, contact any member of the project or Jonathan Mühlenpfordt (muehlenpfordt [at] neon-energie [dot] de or +49-178-137 2 731). You are also invited to share your own Data Packages through our platform, if it fits with the overall vision for the project.
