Finland — Energy Infrastructure

OverWatts maps 219 energy assets in Finland across 9 layers — the 40th-largest mapped base of 157 countries. They include 191 power plants, 7 LNG terminals and 6 pipelines. Operating generation capacity is 15.2 GW, led by nuclear at 30%.

The companies named on the most assets are OX2 AB (18), Ilmatar Energy Oy (14) and Helen Oy (9), counting both ownership and operatorship. Half of Finland's mapped assets in service predate 2013 (median commissioning year of the 71 with a known date), 33 came online in the past decade and the oldest still listed is Lappeenranta Cement Plant, dating from 1914. 40+ projects are under construction or proposed, led by Halla wind farm (2.1 GW).
