Publication of two major new versions of the GAP and DAP in 2026: focusing on storage, geothermal energy, net metering and e-mobility

January 2026. WAPP mapping

Between 2018 and 2025, the West African Power Pool underwent a major transformation thanks to a strategy focused on increasing generation capacity, integrating renewable energy, and progressively interconnecting national grids. WAPP supported the commissioning of new hydroelectric (such as Souapiti in Guinea and Gouina in Mali), thermal, and solar power plants, bringing the region's installed capacity to over 30,000 MW by 2025. At the same time, the transmission network was significantly strengthened with the construction of over 5,000 km of high-voltage lines, including the key interconnections CLSG (Côte d'Ivoire–Liberia–Sierra Leone–Guinea), OMVG (Senegal–Gambia–Guinea-Bissau–Guinea), and the CEB–Nigeria–Niger–Burkina Faso northern backbone. These infrastructures have enabled increased cross-border trade, improved grid stability, and brought the region closer to the goal of a fully operational regional electricity market, thereby reducing production costs and strengthening energy security for Member States.

The current state of the WAPP (including Mauritania) electricity system is evolving rapidly, as evidenced by the mapping of transmission and generation capacities for the end of 2025. In total, more than 277 power plants have been identified (> 1 MW), 669 substations, and 51,000 km of transmission lines have been constructed and georeferenced. By the end of December 2025, the installed capacity across the entire region is estimated to reach 31.4 GW. The share of renewable energy is estimated at approximately 27%, as shown in the following table:

 

Type	Capacity (MW)	Share
Biomass	78	0%
Solar	1127	4%
Wind	325	1%
Hydro	7054	23%
Thermal (without Gas)	4266	14%
Gas	18542	59%
TOTAL WAPP	31392	100%
Renewable share	8584	27%

More than 7.4 GW of power generation is expected to be delivered in the short term over the next few years, bringing the area's capacity to over 38.8 GW. The map below shows the distribution of power plants, with a significant disparity in the distribution of technologies, depending on the area's potential.

 

 

June 2024 - Release of the new GEOSIM 6!

As a result of a significant investment, GEOSIM 6 now offers a new vision geospatial data access and compilation. GEOSIM 6 is now based on an Open Source PostGreSQL/PostGIS database installed in parallel with the software. GEOSIM can nevertheless connect to an existing PostGreSQL database to access a company's georeferenced information. This major development allows GEOSIM to work directly with QGIS-type software for managing geospatial data. GEOSIM nevertheless retains the possibility of working with the Manifold GIS software as for previous versions. It is therefore also possible to centralize GIS data within a single database accessible by multiple users connected to the company's internal network.

Other modifications have also been made to version 6 to make the software even faster and more user-friendly...

New record year in 2023 for sales of software and IT solutions in the Energy sector for IED Digital Solutions. The diffusion of IED solutions is accelerating on the African market, particularly among private players (Consulting companies, international engineering companies) and national electricity utilities. GISELEC and GEOSIM software are driving the software market with significantly increasing demand. Good prospects for 2024 which will see the arrival of a major version of GEOSIM that is increasingly integrated into our clients' existing information systems and databases, new functional developments on GISELEC and the development of mobile IMS and geolocation solutions for potential clients...

Dec. 2023. IED establishes the most updated cartography for the WAPP power system (Mauritania included) mapping the transmission network and generation capacities for the whole area.

In total, more than 238 powerplants, 615 substations and 48,400 km of transmission lines have been built and georeferenced.

By december 2023, it is estimated that the installed capacity in the whole area reaches 30 GW. The renewable energy share is estimated to be around 26% as described in the following table:

Type	Capacity (MW)	Part
Biomass	32	0%
Solar	900	3%
Wind	329	1%
Hydro	6844	23%
Thermal	4193	14%
Gas	17696	59%
TOTAL WAPP	29997	100%
Part ENR WAPP	7776	26%

More than 6.5 GW of generation is to be delivered in the short term in the next few years, which will bring the capacity of the area to more than 36.5 GW. The map below shows the distribution of power plants, with a wide disparity in the distribution of technologies, depending on the potential of the area.
