GEOSIM is a GIS based software designed for quickly creating highly interactive rural electrification planning scenarios.

Strengthened by a rich heritage based on rural electrification planning experiences and developped in several countries, GEOSIM is now used by numbers of organisations, consultant companies and public institutions in Asia and Africa. With a fully documented set of 4 main modules, GEOSIM has become the most innovative and powerful GIS based planning tool software exploiting all the power of the GIS capability.

GEOSIM offers various benefits to users:

- An easy-to-use graphical user interface that simplifies the management and publishing of rural electrification planning results.

- The customisation of every aspect of rural electrification scenarios and the rapid integration of specific parameters and hypothesis is today accessible to all.

- A wide range of renewable options is studied for rural electrification planning allowing a maximal flexibility to users for designing effective plans taking into account ground realities.


Through the concepts of Development Poles and hinterlands (or attraction areas), GEOSIM Spatial Analyst® identifies and analyses settlements with high potential for social and economic development which should be electrified first, so as to maximise impact of rural electrification
In the present situation of scarce resource and unprofitable rural electrification projects, GEOSIM Spatial Analyst® strives to optimise the mandatory public subsidy by targeting in priority projects which will benefit to the largest number of people through access to improved social services (health, education, drinking water, etc.) and local economic opportunities (business, employment, etc.).


Before actually undertaking least-cost sizing of decentralised supply options, the Network Options® modules first defines the areas concerned by rural electrification, i.e. areas not likely to be connected to the grid in the near future. This forecast of the national grid network is done by either entering directly the forecasted grid extensions as input data, or by simulating the extension of the national grid, taking into account several possible constraints (distance to substations, investment budgets, available energy on the grid…). Then the module finds the best decentralised options to supply electricity to previously identified Development Poles and their surrounding settlements, using one of the following methods: Selected projects are those with the lowest actualized cost of electricity or technologies are ranked by preference.
