How big is South Sudan's transmission network?

OverWatts maps 96 km of transmission line in South Sudan, 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 South Sudan's grid?

Most of the mapped network is high voltage (220–379 kV): 96 km of 96 km. The highest voltage tagged anywhere in the country is 220 kV.

How complete is the grid map for South Sudan?

Sparse — 0.2 km of mapped line per 1,000 km² of land, ahead of 1% 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 South Sudan to its neighbours?

32 MW of cross-border transfer capacity to Sudan, plus 700 MW planned. Capacities are from the Global Transmission Database (v1.0, 2023).

South Sudan power grid

OverWatts maps 96 km of South Sudan's electricity transmission network across 9 line segments and 0 substations, the 146th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 96 km — 100% of the mapped length, with the highest tagged voltage at 220 kV. That works out to 0.2 km per 1,000 km² of land — sparse OpenStreetMap coverage, ahead of 1% of mapped countries. It is connected to 1 neighbouring grid by 32 MW of existing cross-border transfer capacity, with a further 700 MW planned.

This grades how completely OpenStreetMap has drawn South Sudan'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.
