Indonesia — Energy Infrastructure

OverWatts maps 1,101 energy assets in Indonesia across 14 layers — the 8th-largest mapped base of 157 countries. They include 482 coal / uranium mines, 288 power plants and 72 oil & gas fields. Operating generation capacity is 94.5 GW, led by coal at 63%. Refining capacity is about 1,226 kb/d.

The companies named on the most assets are PT PLN (Persero) (103), PT Pertamina Gas (27) and small shareholder(s) (18), counting both ownership and operatorship. Half of Indonesia's mapped assets in service predate 2013 (median commissioning year of the 698 with a known date), 245 came online in the past decade and the oldest still listed is Semen Padang Cement Plant, dating from 1913. 40+ projects are under construction or proposed, led by Kayan 5 hydroelectric plant (3.3 GW).
