How big is Russia's transmission network?

OverWatts maps 165,600 km of transmission line in Russia, across 13,270 segments, plus 295 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 Russia's grid?

Most of the mapped network is high voltage (220–379 kV): 114,300 km of 165,600 km. The highest voltage tagged anywhere in the country is 1,150 kV.

How complete is the grid map for Russia?

Partial — 9.8 km of mapped line per 1,000 km² of land, ahead of 35% 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 Russia?

МРСК-1 are tagged as operators on mapped segments. Operator tags are present on 0% of Russia's segments, so this ranks who is *recorded*, not market share.

What interconnectors connect Russia to its neighbours?

5,885 MW of cross-border transfer capacity to Belarus, China, Georgia, Mongolia, Kazakhstan, plus 1,000 MW planned. Capacities are from the Global Transmission Database (v1.0, 2023).

Russia power grid

OverWatts maps 165,600 km of Russia's electricity transmission network across 13,270 line segments and 295 substations, the 4th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 114,300 km — 69% of the mapped length, with the highest tagged voltage at 1,150 kV. That works out to 9.8 km per 1,000 km² of land — partial OpenStreetMap coverage, ahead of 35% of mapped countries. It is connected to 5 neighbouring grids by 5,885 MW of existing cross-border transfer capacity, with a further 1,000 MW planned.

This grades how completely OpenStreetMap has drawn Russia'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.

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.
