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.

 

 

June 2022. Release of the new version 5 of the NAP Transmission Network Analysis and Planning software.

NAP (Network Analysis and Planning) 

is a complete software package for the analysis and planning of electrical transmission networks (MV and HV). Widely used for load flow studies, short circuit calculation and incident simulation, it allows network analysis and planning of new extensions (Transmission Master Plan, power plant interconnection study...)

The new version 5 (published in 2022) is now available and offers a new data management completely modernized with new capacities of data entry and visualization of the networks in mixed mode single line and cartographic (GIS). NAP 5 also integrates in an optimized way new ENR generators (solar and wind intermittent) and storage modules for more detailed network analyses and to meet current requirements. Its new automatic calculation engine also allows to compare different scenarios and identify the most appropriate solution in the case of transmission network extension studies.

 

A one-click installation, NAP 5 uses the latest technology to provide planners and decision makers with fast, professional results through a modern, user-friendly interface.

The NAP 2022 version can now be tested for free on our Website.

Feb. 2022. IED establishes the most up-to-date mapping of the WAPP area with the latest information in early 2022.

In total, more than 200 powerplants, 570 substations and 1040 transmission lines have been georeferenced.

In 2022, it is estimated that the installed capacity in the whole area exceeds 25 GW. The ENR share is estimated to be around 31% as described in the following table:

Type	Capacity (MW)	Part
Biomass	32	0%
Solar	535	2%
Wind	203	1%
Hydro	7130	28%
Thermal	2013	8%
Gas	15744	61%
TOTAL WAPP	25720	100%
Part ENR WAPP	7919	31%

More than 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 30 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.

 

The database built will be able to feed the NAP and GAP software for energy supply stability studies (GAP) and transport network studies (NAP).

Jul.2021: New PV minigrids planning module

In order to provide more detailed and accurate electrification options, the latest version GEOSIM 5.6 now includes a new and improved planning module for PV electrification options that strengthens the previous approach of solar mini-grids.

3 mini-grid configurations can now be studied:

• PV Hybrid Diesel Project: diesel generator with solar hybridisation. From a solar point of view, this module is equivalent to a grid connected system, the hybridisation reduces the load on the diesel, which however remains in permanent operation.
• PV/Battery/Diesel: Solar, batteries, diesel. Solar based mini-grid with diesel support to ensure a certain quality of service.
• PV/Battery: Solar, batteries for smaller mini-grids

The discounted levelized cost study can also be carried out on the long term with a more precise and geospatial estimate of the solar potential, calculated per site and derived from the solar maps available on the internet (GlobalSolarAtlas...)
