Fraunhofer ISE launches online energy database


The Fraunhofer Institute for Solar Energy Systems (ISE) has launched a free online electrical energy database for Germany.

"By making the data available on this website, it is our intent to promote transparent and objective discussions relating to all factors regarding the energy transformation in Germany," said Fraunhofer ISE Director Eicke Weber.

The site offers interactive data charts that can be individually tailored by the user and that display the power produced in Germany from all conventional and renewable sources as well as import and export data.

The comprehensive database is available online at

"Our graphs of electricity production are very popular: for one, because we collect the data from several neutral sources and secondly because we continually update the time series data promptly," said Bruno Burger, who heads the data collection efforts and the strategic development of the database at Fraunhofer ISE.

Users can customize the graphs themselves according to their needs: power, energy and prices can be selected, different energy sources can be chosen and the parameters can be displayed as absolute values or as percentages. At present, the data are presented and updated on a weekly basis. In the future, some of the data will be presented on a daily time scale.

The database has already piqued the interest of users from the other side of the globe. “The Japanese Ministry for the Environment had 200 pages from the energy charts translated into Japanese in order to display the data on their own homepage,” Burger added.
