How big is Senegal's transmission network?

OverWatts maps 2,061 km of transmission line in Senegal, across 50 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 Senegal's grid?

Most of the mapped network is high voltage (220–379 kV): 2,061 km of 2,061 km. The highest voltage tagged anywhere in the country is 225 kV.

How complete is the grid map for Senegal?

Partial — 10.6 km of mapped line per 1,000 km² of land, ahead of 39% 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 Senegal?

OMVG Energy Project, Senelec are tagged as operators on mapped segments. Operator tags are present on 4% of Senegal's segments, so this ranks who is *recorded*, not market share.

What interconnectors connect Senegal to its neighbours?

500 MW of cross-border transfer capacity to Mali, Mauritania, plus 2,400 MW planned. Capacities are from the Global Transmission Database (v1.0, 2023).

Senegal power grid

OverWatts maps 2,061 km of Senegal's electricity transmission network across 50 line segments and 0 substations, the 88th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 2,061 km — 100% of the mapped length, with the highest tagged voltage at 225 kV. That works out to 10.6 km per 1,000 km² of land — partial OpenStreetMap coverage, ahead of 39% of mapped countries. It is connected to 2 neighbouring grids by 500 MW of existing cross-border transfer capacity, with a further 2,400 MW planned.

This grades how completely OpenStreetMap has drawn Senegal'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. 4% of segments carry a real line name and 4% an operator tag.

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.
