Lithuania · electricity network
Lithuania power grid
OverWatts maps 1,788 km of Lithuania's electricity transmission network across 232 line segments and 25 substations, the 94th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 1,736 km — 97% of the mapped length, with the highest tagged voltage at 400 kV. That works out to 28.1 km per 1,000 km² of land — moderate OpenStreetMap coverage, ahead of 69% of mapped countries. It is connected to 3 neighbouring grids by 2,651 MW of existing cross-border transfer capacity, with a further 1,500 MW planned.
OpenStreetMap coverage
This grades how completely OpenStreetMap has drawn Lithuania'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. 35% of segments carry a real line name and 0% an operator tag.

232 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 Lithuania's transmission network?
- OverWatts maps 1,788 km of transmission line in Lithuania, across 232 segments, plus 25 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 Lithuania's grid?
- Most of the mapped network is high voltage (220–379 kV): 1,736 km of 1,788 km. The highest voltage tagged anywhere in the country is 400 kV.
- How complete is the grid map for Lithuania?
- Moderate — 28.1 km of mapped line per 1,000 km² of land, ahead of 69% 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 Lithuania to its neighbours?
- 2,651 MW of cross-border transfer capacity to Belarus, Latvia, Sweden, plus 1,500 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.
