Portugal — Energy Infrastructure

OverWatts maps 121 energy assets in Portugal across 9 layers — the 55th-largest mapped base of 157 countries. They include 84 power plants, 14 grid storages and 8 cement plants. Operating generation capacity is 14.9 GW, led by hydro at 48%. Refining capacity is about 320 kb/d.

The companies named on the most assets are EDP SA (28), Crédit Agricole Assurances SA (10) and ENGIE SA (10), counting both ownership and operatorship. Half of Portugal's mapped assets in service predate 2005 (median commissioning year of the 78 with a known date), 18 came online in the past decade and the oldest still listed is Outao Cement Plant, dating from 1904. 26 projects are under construction or proposed, led by Nortada Offshore Floating wind farm (2.0 GW).
