GEOSIM® is a decision making tool for rural electrification planning. The software is based on Geographic Information System (GIS) technology and operates with a MANIFOLD® environment.
GEOSIM® consists of 4 interdependent modules:

  • GEOSIM Spatial Analyst®
  • GEOSIM Demand Analyst®
  • GEOSIM Network Options®
  • GEOSIM Distributed Energy®



GEOSIM Spatial Analyst® is a module dedicated to the analysis of local dynamics within the studied area, prior to the socioeconomic optimisation phase of electrification solutions.
Through the concepts of development poles and hinterlands (or attraction areas), GEOSIM Spatial Analyst® identifies and analyses settlements with potential for social and economic development and that should be electrified first, so as to improve impact of rural electrification.
Additionally, GEOSIM Spatial Analyst® enables to identify localities with low access to socioeconomic services, and requiring specific attention.


GEOSIM Demand Analyst® aims at modelling and forecasting the demand for electricity of the studied area at the planning horizon. Input data can be collected through field visits or issued from extrapolations or hypothesis done by the user.
As outputs, GEOSIM Demand Analyst® provides typical load duration curves and key figures related to the number of clients (MV/LV), the yearly consumption and the peak demand for each locality of the studied area.


GEOSIM Network Options® identifies the most appropriate electrification solution for localities of the study area at the planning horizon, on the basis of a cost-benefits optimisation. Considered options, in clusters (group of localities) or in isolated mode, are :

  • Connection to the national grid,
  • Supply from small hydro power plants (with or without back-up),
  • Supply from biomass power plants (with or without back-up),
  • Supply from diesel gensets.

GEOSIM Network Options® also offers the possibility of net-metering for renewable energy based projects , enabling both (i) to purchase lack of energy from the grid or (ii) to inject excess of energy into the grid..
Depending on available funds or results based objectives set by the planner, the module provides a list of localities likely to be electrified by the planning horizon, and related supply options and costs.


Access to basic energy services is a  necessity for settlements located far from development poles and not electrified at the planning horizon.
Based on GEOSIM Spatial Analyst®  and GEOSIM Network Options® results, GEOSIM Distributed Energy® identifies localities that should benefit from projects oriented towards access to basic energy services from alternatives sources (photovoltaic systems, multifunctional platforms, etc...). This modules provides systems sizing and related required investments for targeted localities.


GEOSIM® requires the availability of georeferenced data and a configuration adapted to the studied context.
The use of GEOSIM®  requires specific training, adapted to the users expectations, and proposed with the software.
The use of the software is facilitated by user friendly interfaces.
