Colombia · electricity network
Colombia power grid
OverWatts maps 12,600 km of Colombia's electricity transmission network across 811 line segments and 23 substations, the 28th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 8,695 km — 69% of the mapped length, with the highest tagged voltage at 500 kV. That works out to 10.9 km per 1,000 km² of land — partial OpenStreetMap coverage, ahead of 39% of mapped countries. It is connected to 2 neighbouring grids by 743 MW of existing cross-border transfer capacity, with a further 1,900 MW planned.
OpenStreetMap coverage
This grades how completely OpenStreetMap has drawn Colombia'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. 8% of segments carry a real line name and 15% an operator tag.

811 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.

Frequently asked
- How big is Colombia's transmission network?
- OverWatts maps 12,600 km of transmission line in Colombia, across 811 segments, plus 23 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 Colombia's grid?
- Most of the mapped network is high voltage (220–379 kV): 8,695 km of 12,600 km. The highest voltage tagged anywhere in the country is 500 kV.
- How complete is the grid map for Colombia?
- Partial — 10.9 km of mapped line per 1,000 km² of land, ahead of 39% 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 Colombia?
- Interconexión Eléctrica S.A., ISA, Energía de Bogotá and 5 others are tagged as operators on mapped segments. Operator tags are present on 15% of Colombia's segments, so this ranks who is *recorded*, not market share.
- What interconnectors connect Colombia to its neighbours?
- 743 MW of cross-border transfer capacity to Venezuela, Ecuador, plus 1,900 MW planned. Capacities are from the Global Transmission Database (v1.0, 2023).

Network geometry: OpenStreetMap (ODbL) © OpenStreetMap contributors, ingested and measured by OverWatts · derived 2026-07-26. Counts every mapped line of 220 kV and above; the map layer draws the ≥380 kV backbone only, so it shows less than is measured here.
