How big is Guyana's transmission network?

OverWatts maps 45 km of transmission line in Guyana, across 1 segments, plus 0 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 Guyana's grid?

Most of the mapped network is high voltage (220–379 kV): 45 km of 45 km. The highest voltage tagged anywhere in the country is 230 kV.

How complete is the grid map for Guyana?

Sparse — 0.2 km of mapped line per 1,000 km² of land, ahead of 1% 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 Guyana?

EDELCA are tagged as operators on mapped segments. Operator tags are present on 100% of Guyana's segments, so this ranks who is *recorded*, not market share.

Guyana power grid

OverWatts maps 45 km of Guyana's electricity transmission network across 1 line segments and 0 substations, the 150th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 45 km — 100% of the mapped length, with the highest tagged voltage at 230 kV. That works out to 0.2 km per 1,000 km² of land — sparse OpenStreetMap coverage, ahead of 1% of mapped countries.

This grades how completely OpenStreetMap has drawn Guyana'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. 100% of segments carry a real line name and 100% an operator tag.
