Saudi Arabia · electricity network
Saudi Arabia power grid
OverWatts maps 27,300 km of Saudi Arabia's electricity transmission network across 1,410 line segments and 44 substations, the 13th most-mapped grid of 153 countries. Its backbone is extra-high voltage (380–764 kV), carrying 24,700 km — 91% of the mapped length, with the highest tagged voltage at 500 kV. That works out to 14.2 km per 1,000 km² of land — moderate OpenStreetMap coverage, ahead of 46% of mapped countries. It is connected to 5 neighbouring grids by 3,850 MW of existing cross-border transfer capacity, with a further 5,650 MW planned.
OpenStreetMap coverage
This grades how completely OpenStreetMap has drawn Saudi Arabia'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.

1,410 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 Saudi Arabia's transmission network?
- OverWatts maps 27,300 km of transmission line in Saudi Arabia, across 1,410 segments, plus 44 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 Saudi Arabia's grid?
- Most of the mapped network is extra-high voltage (380–764 kV): 24,700 km of 27,300 km. The highest voltage tagged anywhere in the country is 500 kV.
- How complete is the grid map for Saudi Arabia?
- Moderate — 14.2 km of mapped line per 1,000 km² of land, ahead of 46% 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.
- What interconnectors connect Saudi Arabia to its neighbours?
- 3,850 MW of cross-border transfer capacity to Kuwait, United Arab Emirates, Qatar, Bahrain, Oman, plus 5,650 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.
