Armenia · electricity network
Armenia power grid
OverWatts maps 1,507 km of Armenia's electricity transmission network across 115 line segments and 1 substations, the 98th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 1,370 km — 91% of the mapped length, with the highest tagged voltage at 400 kV. That works out to 52.7 km per 1,000 km² of land — strong OpenStreetMap coverage, ahead of 89% of mapped countries. It is connected to 2 neighbouring grids by 550 MW of existing cross-border transfer capacity, with a further 1,200 MW planned.
OpenStreetMap coverage
This grades how completely OpenStreetMap has drawn Armenia'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. 1% of segments carry a real line name and 0% an operator tag.

115 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.

Frequently asked
- How big is Armenia's transmission network?
- OverWatts maps 1,507 km of transmission line in Armenia, across 115 segments, plus 1 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 Armenia's grid?
- Most of the mapped network is high voltage (220–379 kV): 1,370 km of 1,507 km. The highest voltage tagged anywhere in the country is 400 kV.
- How complete is the grid map for Armenia?
- Strong — 52.7 km of mapped line per 1,000 km² of land, ahead of 89% 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 Armenia to its neighbours?
- 550 MW of cross-border transfer capacity to Iran, Georgia, plus 1,200 MW planned. 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.
