Guinea · electricity network
Guinea power grid
OverWatts maps 812 km of Guinea's electricity transmission network across 34 line segments and 0 substations, the 116th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 812 km — 100% of the mapped length, with the highest tagged voltage at 225 kV. That works out to 3.4 km per 1,000 km² of land — sparse OpenStreetMap coverage, ahead of 13% of mapped countries. No cross-border capacity is recorded today; 2,680 MW is planned.
OpenStreetMap coverage
This grades how completely OpenStreetMap has drawn 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 6% an operator tag.

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

Load against the network
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 Guinea's network
- Transco CLSG2 100%
Segment counts from OSM `operator` tags, merged across spellings. Present on 6% of segments — this ranks who is recorded, not market share.

Frequently asked
- How big is Guinea's transmission network?
- OverWatts maps 812 km of transmission line in Guinea, across 34 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 Guinea's grid?
- Most of the mapped network is high voltage (220–379 kV): 812 km of 812 km. The highest voltage tagged anywhere in the country is 225 kV.
- How complete is the grid map for Guinea?
- Sparse — 3.4 km of mapped line per 1,000 km² of land, ahead of 13% 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 Guinea?
- Transco CLSG are tagged as operators on mapped segments. Operator tags are present on 6% of Guinea's segments, so this ranks who is *recorded*, not market share.
- What interconnectors connect Guinea to its neighbours?
- None recorded as operating. 2,680 MW is planned across 5 pathways.

Network geometry: OpenStreetMap (ODbL) © OpenStreetMap contributors, ingested and measured by OverWatts · derived 2026-07-26. Counts every mapped line of 220 kV and above; the map layer draws the ≥380 kV backbone only, so it shows less than is measured here.
