North Korea · electricity network
North Korea power grid
OverWatts maps 1,554 km of North Korea's electricity transmission network across 107 line segments and 0 substations, the 96th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 1,554 km — 100% of the mapped length, with the highest tagged voltage at 220 kV. That works out to 12.4 km per 1,000 km² of land — partial OpenStreetMap coverage, ahead of 43% of mapped countries. It is connected to 1 neighbouring grid by 50 MW of existing cross-border transfer capacity.
OpenStreetMap coverage
This grades how completely OpenStreetMap has drawn North Korea'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.

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.

Frequently asked
- How big is North Korea's transmission network?
- OverWatts maps 1,554 km of transmission line in North Korea, across 107 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 North Korea's grid?
- Most of the mapped network is high voltage (220–379 kV): 1,554 km of 1,554 km. The highest voltage tagged anywhere in the country is 220 kV.
- How complete is the grid map for North Korea?
- Partial — 12.4 km of mapped line per 1,000 km² of land, ahead of 43% 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.
- What interconnectors connect North Korea to its neighbours?
- 50 MW of cross-border transfer capacity to China. 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.
