Myanmar · electricity network
Myanmar power grid
OverWatts maps 6,159 km of Myanmar's electricity transmission network across 252 line segments and 0 substations, the 47th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 5,639 km — 92% of the mapped length, with the highest tagged voltage at 500 kV. That works out to 9 km per 1,000 km² of land — partial OpenStreetMap coverage, ahead of 34% of mapped countries. It is connected to 2 neighbouring grids by 231 MW of existing cross-border transfer capacity, with a further 1,600 MW planned.
OpenStreetMap coverage
This grades how completely OpenStreetMap has drawn Myanmar'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 8% an operator tag.

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

231 MW existing · 1.6 GW planned · capacities from the Global Transmission Database v0.1 (CC BY 4.0), existing as of 2023
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 Myanmar's network
Segment counts from OSM `operator` tags, merged across spellings. Present on 8% of segments — this ranks who is recorded, not market share.

Frequently asked
- How big is Myanmar's transmission network?
- OverWatts maps 6,159 km of transmission line in Myanmar, across 252 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 Myanmar's grid?
- Most of the mapped network is high voltage (220–379 kV): 5,639 km of 6,159 km. The highest voltage tagged anywhere in the country is 500 kV.
- How complete is the grid map for Myanmar?
- Partial — 9 km of mapped line per 1,000 km² of land, ahead of 34% 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 Myanmar?
- Department of Power Transmission and System Control are tagged as operators on mapped segments. Operator tags are present on 8% of Myanmar's segments, so this ranks who is *recorded*, not market share.
- What interconnectors connect Myanmar to its neighbours?
- 231 MW of cross-border transfer capacity to China, India, plus 1,600 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.
