Mozambique power grid

OverWatts maps 4,352 km of Mozambique's electricity transmission network across 140 line segments and 6 substations, the 62nd most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 2,277 km — 52% of the mapped length, with the highest tagged voltage at 533 kV. That works out to 5.3 km per 1,000 km² of land — sparse OpenStreetMap coverage, ahead of 19% of mapped countries. It is connected to 3 neighbouring grids by 5,800 MW of existing cross-border transfer capacity, with a further 50 MW planned.

OpenStreetMap coverage

Sparse5.3 km / 1,000 km²ahead of 19% of 153 mapped countries

This grades how completely OpenStreetMap has drawn Mozambique'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. 9% of segments carry a real line name and 12% an operator tag.

Mapped line length by voltage

140 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 Mozambique's network

Segment counts from OSM `operator` tags, merged across spellings. Present on 12% of segments — this ranks who is recorded, not market share.

How Mozambique compares · mapped grid by country

Frequently asked

How big is Mozambique's transmission network?
OverWatts maps 4,352 km of transmission line in Mozambique, across 140 segments, plus 6 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 Mozambique's grid?
Most of the mapped network is high voltage (220–379 kV): 2,277 km of 4,352 km. The highest voltage tagged anywhere in the country is 533 kV.
How complete is the grid map for Mozambique?
Sparse — 5.3 km of mapped line per 1,000 km² of land, ahead of 19% 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 Mozambique?
Electricidade de Moçambique, Eskom, EdM are tagged as operators on mapped segments. Operator tags are present on 12% of Mozambique's segments, so this ranks who is *recorded*, not market share.
What interconnectors connect Mozambique to its neighbours?
5,800 MW of cross-border transfer capacity to South Africa, Swaziland, Zimbabwe, plus 50 MW planned. Capacities are from the Global Transmission Database (v1.0, 2023).
