Benin · electricity network
Benin power grid
OverWatts maps 133 km of Benin's electricity transmission network across 4 line segments and 2 substations, the 144th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 133 km — 100% of the mapped length, with the highest tagged voltage at 330 kV. That works out to 1.1 km per 1,000 km² of land — sparse OpenStreetMap coverage, ahead of 6% of mapped countries. It is connected to 3 neighbouring grids by 1,005 MW of existing cross-border transfer capacity, with a further 2,200 MW planned.
OpenStreetMap coverage
This grades how completely OpenStreetMap has drawn Benin'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. 50% of segments carry a real line name and 0% an operator tag.

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

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.

Frequently asked
- How big is Benin's transmission network?
- OverWatts maps 133 km of transmission line in Benin, across 4 segments, plus 2 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 Benin's grid?
- Most of the mapped network is high voltage (220–379 kV): 133 km of 133 km. The highest voltage tagged anywhere in the country is 330 kV.
- How complete is the grid map for Benin?
- Sparse — 1.1 km of mapped line per 1,000 km² of land, ahead of 6% 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 Benin to its neighbours?
- 1,005 MW of cross-border transfer capacity to Ghana, Togo, Nigeria, plus 2,200 MW planned. 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.
