Power Plants in Sweden

Sweden has 186 power plants mapped on the OverWatts open energy atlas — the 22nd-largest fleet of the 155 countries that hold any, and 0.6% of the world's mapped total. Of these, 105 operating and 74 under construction or proposed. Operating generation capacity totals 29.7 GW across 105 utility-scale plants of 100 MW and above. The largest is Sylen offshore wind farm (8.7 GW).

The largest owner-operators are Vattenfall AB (45), Statkraft AS (14) and Uniper SE (10) — Vattenfall AB alone is named on 24% of them. Half of Sweden's power plants in service predate 1976 (median commissioning year of the 101 with a known date), 32 came online in the past decade and the oldest still listed is Olidan hydroelectric plant, dating from 1910. 74 are in the pipeline, led by Sylen offshore wind farm (8.7 GW), under construction. They account for 86% of every energy asset OverWatts maps in Sweden.
