Sweden — Energy Infrastructure

OverWatts maps 216 energy assets in Sweden across 9 layers — the 41st-largest mapped base of 157 countries. They include 186 power plants, 8 iron ore mines and 6 iron & steel plants. Operating generation capacity is 29.7 GW, led by hydro at 33%.

The companies named on the most assets are Vattenfall AB (47), Statkraft AS (14) and Fortum Oyj (11), counting both ownership and operatorship. Half of Sweden's mapped assets in service predate 1975 (median commissioning year of the 114 with a known date), 33 came online in the past decade and the oldest still listed is Olidan hydroelectric plant, dating from 1910. 40+ projects are under construction or proposed, led by Sylen offshore wind farm (8.7 GW).
