How big is Serbia's transmission network?

OverWatts maps 3,345 km of transmission line in Serbia, across 159 segments, plus 21 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 Serbia's grid?

Most of the mapped network is extra-high voltage (380–764 kV): 1,673 km of 3,345 km. The highest voltage tagged anywhere in the country is 400 kV.

How complete is the grid map for Serbia?

Strong — 43.9 km of mapped line per 1,000 km² of land, ahead of 82% 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 Serbia?

Elektromreža Srbije, Електромрежа Србиjе, EMS are tagged as operators on mapped segments. Operator tags are present on 13% of Serbia's segments, so this ranks who is *recorded*, not market share.

What interconnectors connect Serbia to its neighbours?

5,109 MW of cross-border transfer capacity to Hungary, Kosovo, Romania, Montenegro, North Macedonia, Bosnia and Herzegovina, Albania, Croatia and 1 more, plus 10,130 MW planned. Capacities are from the Global Transmission Database (v1.0, 2023).

Serbia power grid

OverWatts maps 3,345 km of Serbia's electricity transmission network across 159 line segments and 21 substations, the 70th most-mapped grid of 153 countries. Its backbone is extra-high voltage (380–764 kV), carrying 1,673 km — 50% of the mapped length, with the highest tagged voltage at 400 kV. That works out to 43.9 km per 1,000 km² of land — strong OpenStreetMap coverage, ahead of 82% of mapped countries. It is connected to 9 neighbouring grids by 5,109 MW of existing cross-border transfer capacity, with a further 10,130 MW planned.

This grades how completely OpenStreetMap has drawn Serbia'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. 3% of segments carry a real line name and 13% an operator tag.

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 Serbia's network

Segment counts from OSM `operator` tags, merged across spellings. Present on 13% of segments — this ranks who is recorded, not market share.
