Peru power grid

OverWatts maps 11,800 km of Peru's electricity transmission network across 349 line segments and 9 substations, the 29th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 8,962 km — 76% of the mapped length, with the highest tagged voltage at 500 kV. That works out to 9 km per 1,000 km² of land — partial OpenStreetMap coverage, ahead of 34% of mapped countries. It is connected to 1 neighbouring grid by 100 MW of existing cross-border transfer capacity, with a further 1,900 MW planned.

OpenStreetMap coverage

Partial9 km / 1,000 km²ahead of 34% of 153 mapped countries

This grades how completely OpenStreetMap has drawn Peru'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 7% an operator tag.

Mapped line length by voltage

349 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.

Operators tagged on Peru's network

Segment counts from OSM `operator` tags, merged across spellings. Present on 7% of segments — this ranks who is recorded, not market share.

How Peru compares · mapped grid by country

Frequently asked

How big is Peru's transmission network?
OverWatts maps 11,800 km of transmission line in Peru, across 349 segments, plus 9 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 Peru's grid?
Most of the mapped network is high voltage (220–379 kV): 8,962 km of 11,800 km. The highest voltage tagged anywhere in the country is 500 kV.
How complete is the grid map for Peru?
Partial — 9 km of mapped line per 1,000 km² of land, ahead of 34% 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 Peru?
Enersur, REP, Transmantaro and 3 others are tagged as operators on mapped segments. Operator tags are present on 7% of Peru's segments, so this ranks who is *recorded*, not market share.
What interconnectors connect Peru to its neighbours?
100 MW of cross-border transfer capacity to Ecuador, plus 1,900 MW planned. Capacities are from the Global Transmission Database (v1.0, 2023).
