How big is Eswatini's transmission network?

OverWatts maps 141 km of transmission line in Eswatini, across 5 segments, plus 1 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 Eswatini's grid?

Most of the mapped network is extra-high voltage (380–764 kV): 141 km of 141 km. The highest voltage tagged anywhere in the country is 400 kV.

How complete is the grid map for Eswatini?

Partial — 7.8 km of mapped line per 1,000 km² of land, ahead of 30% 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.

Eswatini power grid

OverWatts maps 141 km of Eswatini's electricity transmission network across 5 line segments and 1 substations, the 142nd most-mapped grid of 153 countries. Its backbone is extra-high voltage (380–764 kV), carrying 141 km — 100% of the mapped length, with the highest tagged voltage at 400 kV. That works out to 7.8 km per 1,000 km² of land — partial OpenStreetMap coverage, ahead of 30% of mapped countries.

This grades how completely OpenStreetMap has drawn Eswatini'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.

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