Mauritania · electricity network
Mauritania power grid
OverWatts maps 630 km of Mauritania's electricity transmission network across 6 line segments and 0 substations, the 124th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 630 km — 100% of the mapped length, with the highest tagged voltage at 225 kV. That works out to 0.6 km per 1,000 km² of land — sparse OpenStreetMap coverage, ahead of 3% of mapped countries. It is connected to 1 neighbouring grid by 250 MW of existing cross-border transfer capacity.
OpenStreetMap coverage
This grades how completely OpenStreetMap has drawn Mauritania's network — not how much network exists. Large, sparsely-populated countries score low for geographic reasons alone, and every kilometre here is mapped length, so the totals are a floor rather than an operator-reported figure. 33% of segments carry a real line name and 33% an operator tag.
Mapped line length by voltage
- 220–379 kV630 km 100%
6 segments · a segment is credited to the country containing its midpoint, so a border-crossing line counts once, on one side.

On the interactive map
Load against the network
Where there is room to connect a new load depends on published hosting capacity, which most operators release only as their own map. OverWatts does not yet ingest those feeds, so these are the density measures the open data supports — generation and mapped demand against mapped network — not a headroom figure.
Operators tagged on Mauritania's network
- SOMELEC2 100%
Segment counts from OSM `operator` tags, merged across spellings. Present on 33% of segments — this ranks who is recorded, not market share.

Frequently asked
- How big is Mauritania's transmission network?
- OverWatts maps 630 km of transmission line in Mauritania, across 6 segments, plus 0 substations. This is mapped length from OpenStreetMap, not an operator-reported total — where OSM is incomplete the figure is a floor, never a ceiling.
- What voltage is Mauritania's grid?
- Most of the mapped network is high voltage (220–379 kV): 630 km of 630 km. The highest voltage tagged anywhere in the country is 225 kV.
- How complete is the grid map for Mauritania?
- Sparse — 0.6 km of mapped line per 1,000 km² of land, ahead of 3% of the 153 countries with any mapped grid. Coverage grades how completely OpenStreetMap has drawn the network, not how much network exists; large, sparsely-populated countries score low for geographic reasons alone.
- Who operates the grid in Mauritania?
- SOMELEC are tagged as operators on mapped segments. Operator tags are present on 33% of Mauritania's segments, so this ranks who is *recorded*, not market share.
- What interconnectors connect Mauritania to its neighbours?
- 250 MW of cross-border transfer capacity to Senegal. Capacities are from the Global Transmission Database (v1.0, 2023).

Network geometry: OpenStreetMap (ODbL) © OpenStreetMap contributors, ingested and measured by OverWatts · derived 2026-07-26. Counts every mapped line of 220 kV and above; the map layer draws the ≥380 kV backbone only, so it shows less than is measured here.
