Tunisia · electricity network
Tunisia power grid
OverWatts maps 2,817 km of Tunisia's electricity transmission network across 130 line segments and 2 substations, the 77th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 2,491 km — 88% of the mapped length, with the highest tagged voltage at 400 kV. That works out to 18 km per 1,000 km² of land — moderate OpenStreetMap coverage, ahead of 52% of mapped countries. It is connected to 2 neighbouring grids by 580 MW of existing cross-border transfer capacity, with a further 2,850 MW planned.
OpenStreetMap coverage
This grades how completely OpenStreetMap has drawn Tunisia'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. 39% of segments carry a real line name and 0% an operator tag.

130 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 Tunisia's transmission network?
- OverWatts maps 2,817 km of transmission line in Tunisia, across 130 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 Tunisia's grid?
- Most of the mapped network is high voltage (220–379 kV): 2,491 km of 2,817 km. The highest voltage tagged anywhere in the country is 400 kV.
- How complete is the grid map for Tunisia?
- Moderate — 18 km of mapped line per 1,000 km² of land, ahead of 52% 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 Tunisia to its neighbours?
- 580 MW of cross-border transfer capacity to Libya, Algeria, plus 2,850 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.
