Malaysia — Energy Infrastructure

OverWatts maps 248 energy assets in Malaysia across 14 layers — the 37th-largest mapped base of 157 countries. They include 84 power plants, 64 oil & gas fields and 22 cement plants. Operating generation capacity is 37.1 GW, led by gas at 45%. Refining capacity is about 570 kb/d.

The companies named on the most assets are Petronas Carigali Sdn Bhd (59), Petroliam Nasional Bhd (23) and Tenaga Nasional Bhd (21), counting both ownership and operatorship. Half of Malaysia's mapped assets in service predate 2008 (median commissioning year of the 147 with a known date), 47 came online in the past decade and the oldest still listed is Malayan Cement Rawang Cement Plant, dating from 1953. 40+ projects are under construction or proposed, led by Southern Johor Renewable Energy Corridor solar farm (4.0 GW).
