Gambia power grid

OverWatts maps 140 km of the Gambia's electricity transmission network across 9 line segments and 0 substations, the 143rd most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 140 km — 100% of the mapped length, with the highest tagged voltage at 225 kV. That works out to 9.9 km per 1,000 km² of land — partial OpenStreetMap coverage, ahead of 37% of mapped countries. No cross-border capacity is recorded today; 800 MW is planned.

This grades how completely OpenStreetMap has drawn the Gambia'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. 0% of segments carry a real line name and 0% an operator tag.

Mapped line length by voltage

9 segments · a segment is credited to the country containing its midpoint, so a border-crossing line counts once, on one side.

Frequently asked

How big is the Gambia's transmission network?
OverWatts maps 140 km of transmission line in the Gambia, across 9 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 the Gambia's grid?
Most of the mapped network is high voltage (220–379 kV): 140 km of 140 km. The highest voltage tagged anywhere in the country is 225 kV.
How complete is the grid map for the Gambia?
Partial — 9.9 km of mapped line per 1,000 km² of land, ahead of 37% 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.
What interconnectors connect the Gambia to its neighbours?
None recorded as operating. 800 MW is planned across 1 pathway.
