How big is Brunei's transmission network?

OverWatts maps 65 km of transmission line in Brunei, across 6 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 Brunei's grid?

Most of the mapped network is high voltage (220–379 kV): 65 km of 65 km. The highest voltage tagged anywhere in the country is 275 kV.

How complete is the grid map for Brunei?

Partial — 6 km of mapped line per 1,000 km² of land, ahead of 21% 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.

Brunei · electricity network

Brunei power grid

OverWatts maps 65 km of Brunei's electricity transmission network across 6 line segments and 0 substations, the 147th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 65 km — 100% of the mapped length, with the highest tagged voltage at 275 kV. That works out to 6 km per 1,000 km² of land — partial OpenStreetMap coverage, ahead of 21% of mapped countries.

This grades how completely OpenStreetMap has drawn Brunei'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.

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

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.
