The project

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


Primarily, we will provide information of power plants and time series of electricity consumption and wind and solar generation. We have collected data from Germany and extend the geographical scope step by step. It is also planned to 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 to process the data will be open-source. Data will be published as large CSV files. Read more about our IT approach.

Open data

Currently, energy data is often subject to quite restrictive terms of use (read more). The data on this platform will be provided free of charge to anyone without restriction on its use, including commercial applications. It will be published under a Creative Commons Attribution license, an open license that allows any use and derivative work. 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.

The target group

This project targets modelers and analysts in academia, consulting firms, and industry. We do not target journalists or the general public, nor trading departments. Consequently, we will provide no fancy visualization, but boring CSV files. 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 Flensburg,  DIW Berlin, Technical University of Berlin, and Neon Neue Energieökonomik. It is funded by the German Federal Ministry for Economic Affairs and Energy.


We have published a list of data sources, a list of data projects, and an account of the legal situation. A closed beta version of the data platform is online now. An open version is expected in late 2016. The project runs from August 2015 to July 2017.

Get involved!

We want open data, and an open process. A beta version of the platform is now available for registered users. We are involving data owners and future users of the platform in a series of workshops, webinars, and interviews. Potential users are invited to become member of our user group. We will coordinate with various projects that follow similar goals, and with the Open Energy Modelling Initiative. If you like to be involved, contact any member of the project or Jonathan Mühlenpfordt (muehlenpfordt [at] neon-energie [dot] de or +49-157-55 199 715). You can also subscribe to our newsletter. You can also share your own data packages through our platform, if it fits with the overall vision for the project.
