Sri Lanka — Energy Infrastructure
OverWatts maps 44 energy assets in Sri Lanka across 7 layers — the 90th-largest mapped base of 157 countries. They include 30 power plants, 5 cement plants and 3 LNG terminals. Operating generation capacity is 3.4 GW, led by hydro at 30%. Refining capacity is about 50 kb/d.
The companies named on the most assets are Ceylon Electricity Board (13), Ceylon Petroleum Corporation (2) and Ceylon Steel Co Ltd (2), counting both ownership and operatorship. Half of Sri Lanka's mapped assets in service predate 2002 (median commissioning year of the 21 with a known date), 6 came online in the past decade and the oldest still listed is INSEE Ruhunu Cement Plant, dating from 1967. 19 projects are under construction or proposed, led by Poonakary Lake solar farm (700 MW).
