Latvia · electricity network
Latvia power grid
OverWatts maps 1,306 km of Latvia's electricity transmission network across 96 line segments and 18 substations, the 102nd most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 1,305 km — 100% of the mapped length, with the highest tagged voltage at 330 kV. That works out to 20.5 km per 1,000 km² of land — moderate OpenStreetMap coverage, ahead of 58% of mapped countries. It is connected to 1 neighbouring grid by 950 MW of existing cross-border transfer capacity, with a further 2,600 MW planned.
OpenStreetMap coverage
This grades how completely OpenStreetMap has drawn Latvia'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. 53% of segments carry a real line name and 77% an operator tag.

96 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.
Operators tagged on Latvia's network
- Augstsprieguma tīkls72 97%
- Latvenergo2 3%
Segment counts from OSM `operator` tags, merged across spellings. Present on 77% of segments — this ranks who is recorded, not market share.

Frequently asked
- How big is Latvia's transmission network?
- OverWatts maps 1,306 km of transmission line in Latvia, across 96 segments, plus 18 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 Latvia's grid?
- Most of the mapped network is high voltage (220–379 kV): 1,305 km of 1,306 km. The highest voltage tagged anywhere in the country is 330 kV.
- How complete is the grid map for Latvia?
- Moderate — 20.5 km of mapped line per 1,000 km² of land, ahead of 58% 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 Latvia?
- Augstsprieguma tīkls, Latvenergo are tagged as operators on mapped segments. Operator tags are present on 77% of Latvia's segments, so this ranks who is *recorded*, not market share.
- What interconnectors connect Latvia to its neighbours?
- 950 MW of cross-border transfer capacity to Lithuania, plus 2,600 MW planned. Capacities are from the Global Transmission Database (v1.0, 2023).
