Based on the results of the previous project, Geowisol2 will primarily provide information on the temporally and spatially resolved feed-in and demand rates in the German electricity grids. So far, the load structure is only available for parts of the power grid or only in limited detail. The findings will be used for further grid expansion; the data will also be helpful for intensifying sector coupling, for example through the use of energy storage devices.

Part of the Geowisol project has so far involved creating a database between 2015 and 2017, which includes the feed-in rates for electricity from wind and solar energy, spatially distributed. The load time series based on real data were registered as 15-minute mean values and broken down spatially on the basis of the two-digit postcode areas.

Geowisol2 will now be extending this database from January 2019 to December 2021 with data on the feed-in of energy sources such as offshore wind energy, biogas or hydropower. Once the geographical distribution of the energy sources has been determined, this will then be mapped onto the real power lines. The transmission volumes will be analysed and evaluated and serve as a basis for future expansion scenarios.

The BMWi-funded project is being carried out under the direction of the Bremen Institute for Measurement Technology, Automation and Quality Science (BIMAQ) at the University of Bremen in cooperation with Deutsche WindGuard GmbH, Energy & Meteo Systems GmbH and the Offshore Wind Energy Foundation.
