Angola power grid

OverWatts maps 4,588 km of Angola's electricity transmission network across 123 line segments and 10 substations, the 58th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 2,522 km — 55% of the mapped length, with the highest tagged voltage at 400 kV. That works out to 3.7 km per 1,000 km² of land — sparse OpenStreetMap coverage, ahead of 15% of mapped countries. No cross-border capacity is recorded today; 1,200 MW is planned.

OpenStreetMap coverage

Sparse3.7 km / 1,000 km²ahead of 15% of 153 mapped countries

This grades how completely OpenStreetMap has drawn Angola'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. 46% of segments carry a real line name and 11% an operator tag.

Mapped line length by voltage

123 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.

Operators tagged on Angola's network

Segment counts from OSM `operator` tags, merged across spellings. Present on 11% of segments — this ranks who is recorded, not market share.

How Angola compares · mapped grid by country

Frequently asked

How big is Angola's transmission network?
OverWatts maps 4,588 km of transmission line in Angola, across 123 segments, plus 10 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 Angola's grid?
Most of the mapped network is high voltage (220–379 kV): 2,522 km of 4,588 km. The highest voltage tagged anywhere in the country is 400 kV.
How complete is the grid map for Angola?
Sparse — 3.7 km of mapped line per 1,000 km² of land, ahead of 15% 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 Angola?
RNT, Kanazuro Electric S.A, Rede Nacional de Transporte de Electricidade are tagged as operators on mapped segments. Operator tags are present on 11% of Angola's segments, so this ranks who is *recorded*, not market share.
What interconnectors connect Angola to its neighbours?
None recorded as operating. 1,200 MW is planned across 2 pathways.
