Nigeria — Energy Infrastructure

OverWatts maps 337 energy assets in Nigeria across 12 layers — the 25th-largest mapped base of 157 countries. They include 144 oil & gas fields, 84 power plants and 40 pipelines. Operating generation capacity is 13.9 GW, led by gas at 79%. Refining capacity is about 1,095 kb/d.

The companies named on the most assets are NNPC Ltd (106), Nigerian Agip Oil Company Ltd (42) and TotalEnergies EP Nigeria Ltd (26), counting both ownership and operatorship. Half of Nigeria's mapped assets in service predate 2002 (median commissioning year of the 126 with a known date), 21 came online in the past decade and the oldest still listed is Uquo Oil and Gas Field (Nigeria), dating from 1958. 40+ projects are under construction or proposed, led by Mambilla hydroelectric plant (3.0 GW).
