How big is Israel's transmission network?

OverWatts maps 578 km of transmission line in Israel, across 328 segments, plus 6 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 Israel's grid?

Most of the mapped network is extra-high voltage (380–764 kV): 578 km of 578 km. The highest voltage tagged anywhere in the country is 400 kV.

How complete is the grid map for Israel?

Moderate — 25 km of mapped line per 1,000 km² of land, ahead of 66% 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.

Israel power grid

OverWatts maps 578 km of Israel's electricity transmission network across 328 line segments and 6 substations, the 126th most-mapped grid of 153 countries. Its backbone is extra-high voltage (380–764 kV), carrying 578 km — 100% of the mapped length, with the highest tagged voltage at 400 kV. That works out to 25 km per 1,000 km² of land — moderate OpenStreetMap coverage, ahead of 66% of mapped countries.

This grades how completely OpenStreetMap has drawn Israel'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.

328 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.
