Germany power grid

OverWatts maps 17,000 km of Germany's electricity transmission network across 9,804 line segments and 354 substations, the 22nd most-mapped grid of 153 countries. Its backbone is extra-high voltage (380–764 kV), carrying 13,100 km — 77% of the mapped length, with the highest tagged voltage at 600 kV. That works out to 47.7 km per 1,000 km² of land — strong OpenStreetMap coverage, ahead of 87% of mapped countries. It is connected to 11 neighbouring grids by 24,165 MW of existing cross-border transfer capacity, with a further 26,350 MW planned.

OpenStreetMap coverage

Strong47.7 km / 1,000 km²ahead of 87% of 153 mapped countries

This grades how completely OpenStreetMap has drawn Germany'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. 28% of segments carry a real line name and 67% an operator tag.

Mapped line length by voltage

9,804 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 Germany's network

Segment counts from OSM `operator` tags, merged across spellings. Present on 67% of segments — this ranks who is recorded, not market share.

How Germany compares · mapped grid by country

Frequently asked

How big is Germany's transmission network?
OverWatts maps 17,000 km of transmission line in Germany, across 9,804 segments, plus 354 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 Germany's grid?
Most of the mapped network is extra-high voltage (380–764 kV): 13,100 km of 17,000 km. The highest voltage tagged anywhere in the country is 600 kV.
How complete is the grid map for Germany?
Strong — 47.7 km of mapped line per 1,000 km² of land, ahead of 87% 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 Germany?
TenneT TSO, 50Hertz Transmission, Amprion and 5 others are tagged as operators on mapped segments. Operator tags are present on 67% of Germany's segments, so this ranks who is *recorded*, not market share.
What interconnectors connect Germany to its neighbours?
24,165 MW of cross-border transfer capacity to Switzerland, Netherlands, Denmark, France, Luxembourg, Czech Republic, Austria, Norway and 3 more, plus 26,350 MW planned. Capacities are from the Global Transmission Database (v1.0, 2023).
