Ukraine power grid
OverWatts maps 19,200 km of Ukraine's electricity transmission network across 1,054 line segments and 117 substations, the 17th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 14,200 km — 74% of the mapped length, with the highest tagged voltage at 800 kV. That works out to 33.7 km per 1,000 km² of land — moderate OpenStreetMap coverage, ahead of 74% of mapped countries. It is connected to 5 neighbouring grids by 3,649 MW of existing cross-border transfer capacity.
OpenStreetMap coverage
This grades how completely OpenStreetMap has drawn Ukraine'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.

1,054 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.

Segment counts from OSM `operator` tags, merged across spellings. Present on 0% of segments — this ranks who is recorded, not market share.

Frequently asked
- How big is Ukraine's transmission network?
- OverWatts maps 19,200 km of transmission line in Ukraine, across 1,054 segments, plus 117 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 Ukraine's grid?
- Most of the mapped network is high voltage (220–379 kV): 14,200 km of 19,200 km. The highest voltage tagged anywhere in the country is 800 kV.
- How complete is the grid map for Ukraine?
- Moderate — 33.7 km of mapped line per 1,000 km² of land, ahead of 74% 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 Ukraine?
- MAVIR are tagged as operators on mapped segments. Operator tags are present on 0% of Ukraine's segments, so this ranks who is *recorded*, not market share.
- What interconnectors connect Ukraine to its neighbours?
- 3,649 MW of cross-border transfer capacity to Poland, Moldova, Hungary, Slovakia, Romania. 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.
