How big is Kazakhstan's transmission network?

OverWatts maps 31,900 km of transmission line in Kazakhstan, across 1,073 segments, plus 15 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 Kazakhstan's grid?

Most of the mapped network is high voltage (220–379 kV): 22,200 km of 31,900 km. The highest voltage tagged anywhere in the country is 500 kV.

How complete is the grid map for Kazakhstan?

Partial — 11.7 km of mapped line per 1,000 km² of land, ahead of 42% 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 Kazakhstan?

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

What interconnectors connect Kazakhstan to its neighbours?

4,140 MW of cross-border transfer capacity to Kyrgyzstan, Uzbekistan, Russia. Capacities are from the Global Transmission Database (v1.0, 2023).

Kazakhstan power grid

OverWatts maps 31,900 km of Kazakhstan's electricity transmission network across 1,073 line segments and 15 substations, the 11th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 22,200 km — 70% of the mapped length, with the highest tagged voltage at 500 kV. That works out to 11.7 km per 1,000 km² of land — partial OpenStreetMap coverage, ahead of 42% of mapped countries. It is connected to 3 neighbouring grids by 4,140 MW of existing cross-border transfer capacity.

This grades how completely OpenStreetMap has drawn Kazakhstan'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.

1,073 segments · a segment is credited to the country containing its midpoint, so a border-crossing line counts once, on one side.

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.
