Cambodia · electricity network
Cambodia power grid
OverWatts maps 2,080 km of Cambodia's electricity transmission network across 184 line segments and 0 substations, the 86th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 2,080 km — 100% of the mapped length, with the highest tagged voltage at 230 kV. That works out to 11.4 km per 1,000 km² of land — partial OpenStreetMap coverage, ahead of 41% of mapped countries. It is connected to 3 neighbouring grids by 3,030 MW of existing cross-border transfer capacity.
OpenStreetMap coverage
This grades how completely OpenStreetMap has drawn Cambodia'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 3% an operator tag.

On the interactive map
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 Cambodia's network
Segment counts from OSM `operator` tags, merged across spellings. Present on 3% of segments — this ranks who is recorded, not market share.

Frequently asked
- How big is Cambodia's transmission network?
- OverWatts maps 2,080 km of transmission line in Cambodia, across 184 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 Cambodia's grid?
- Most of the mapped network is high voltage (220–379 kV): 2,080 km of 2,080 km. The highest voltage tagged anywhere in the country is 230 kV.
- How complete is the grid map for Cambodia?
- Partial — 11.4 km of mapped line per 1,000 km² of land, ahead of 41% 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 Cambodia?
- Cambodian Power Grid, Sinohydro Kamchay Hydroelectric Project are tagged as operators on mapped segments. Operator tags are present on 3% of Cambodia's segments, so this ranks who is *recorded*, not market share.
- What interconnectors connect Cambodia to its neighbours?
- 3,030 MW of cross-border transfer capacity to Laos, Thailand, Vietnam. Capacities are from the Global Transmission Database (v1.0, 2023).

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.
