Power Plants in Indonesia

Indonesia has 288 power plants mapped on the OverWatts open energy atlas — the 15th-largest fleet of the 155 countries that hold any, and 1.0% of the world's mapped total. Of these, 160 operating and 127 under construction or proposed. Operating generation capacity totals 94.5 GW across 160 utility-scale plants of 100 MW and above. The largest is Banten Suralaya power station (6.0 GW).
