How big is Papua New Guinea's transmission network?

OverWatts maps 44 km of transmission line in Papua New Guinea, across 1 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 Papua New Guinea's grid?

Most of the mapped network is high voltage (220–379 kV): 44 km of 44 km. The highest voltage tagged anywhere in the country is 220 kV.

How complete is the grid map for Papua New Guinea?

Sparse — 0.1 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.

Who operates the grid in Papua New Guinea?

PNG Power Ltd are tagged as operators on mapped segments. Operator tags are present on 100% of Papua New Guinea's segments, so this ranks who is *recorded*, not market share.

Papua New Guinea power grid

OverWatts maps 44 km of Papua New Guinea's electricity transmission network across 1 line segments and 0 substations, the 152nd most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 44 km — 100% of the mapped length, with the highest tagged voltage at 220 kV. That works out to 0.1 km per 1,000 km² of land — sparse OpenStreetMap coverage, ahead of 1% of mapped countries.

This grades how completely OpenStreetMap has drawn Papua New Guinea'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 100% an operator tag.
