The application renpassG!S stands for (r)enewable (en)ergy (pa)thway (s)imulation (s)ystem capable of working with data from geographic information systems (GIS). It is based on the original idea of renpass and closely linked to the Open Energy Modelling Framework (oemof).

This documentation is meant to explain the basic functionality and is structured as follows:

1   Overview

renpassG!S is an easy-to-use application designed to model the cost-minimal dispatch of energy supply systems. Technically speaking, it is a so-called numerical partial equilibrium model of a liberalised electricity market often referred to as fundamental model. Making use of the broad functionality of oemof, the application enables the user to calculate easy-to-understand energy system scenarios for different regions in spreadsheet format (CSV), optimizing the power plant dispatch at minimum costs. Results are exported into spreadsheet format as well an can be easily accessed using suitable software such as LibreOffice Calc or Microsoft Excel.

The general functionality can be derived from the following figure:

Currently, it is developed and maintained at the Center for Sustainable Energy Systems (Zentrum für nachhaltige Energysysteme (ZNES)) in Flensburg. As there are currently some licensing issues concerning the scenario data, this repository only provides the application code. For questions on the data, you can use our contact details below.

2   Application Examples

The model has been used in different research projects. One application was to model future scenarios of the power plant dispatch and day-ahead market price formation in Germany and its interconnected neighbor countries based on operational and marginal costs and the assumption of an inflexible electricity demand. The following figures show some impressions of possible outcomes.

2.1   Hourly power plant dispatch for a week in January

power plant dispatch

2.2   Day-ahead market price formation for a week in May/June

wholesale market price formation

2.3   Annual production per energy carrier for two selected scenarios

annual production

2.4   Diurnal pumped-storage dispatch in Norway for a selected scenario


Currently, a similar spin-off model is adapted to the requirements of the Middle East and North Africa (MENA) region to model possible pathways for the future electricity generation based on a high share of renewables.

3   Installation

renpassG!S is build within oemof and works with the current stable version (v.0.1). Please follow the installation guidelines in the documentation.

If oemof has been installed successfully (including a suitable solver), the application can be run from the directory. Just clone this repository using:

git clone

4   Usage

Energy supply systems can be modelled via oemof's csv-reader functionality. There are two examples on how to use it provided in the oemof example folder.

Once the energy supply systems have been modelled, the application script can be run from the command line:

General usage: [options] NODE_DATA SEQ_DATA

Getting help: -h

Example usage with another solver (standard is CBC): -o gurobi path/to/scenario.csv path/to/scenario-seq.csv

Per default, all result files are written back into the subfolder results.

7   Credits

Oemof and renpassG!S are community projects and have been realised in collaborative work. We therefore thank all people who contributed to the framework and the scenario development, and in particular the following people for their contributions to this first version of renpassG!S:

  • Simon Hilpert and Uwe Krien for the effort they put in the oemof-refactoring
  • Wolf-Dieter Bunke and Marion Christ for the initial scenario development
  • Clemens Wingenbach and Stephan Günther for providing the prior version
  • Frauke Wiese and Gesine Bökenkamp for creating renpass
  • All people at the Center for Sustainable Energy Systems (ZNES) Flensburg
