Gambia · electricity network
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.
OpenStreetMap coverage
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.

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.

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.
