Iran — Energy Infrastructure

OverWatts maps 596 energy assets in Iran across 14 layers — the 16th-largest mapped base of 157 countries. They include 169 power plants, 111 oil & gas fields and 86 pipelines. Operating generation capacity is 91.8 GW, led by gas at 86%. Refining capacity is about 1,745 kb/d.

The companies named on the most assets are National Iranian Oil Co (173), Iran Water and Power Resources Development Co (20) and Iranian Mines & Mining Industries Development & Renovation Organization (19), counting both ownership and operatorship. Half of Iran's mapped assets in service predate 2006 (median commissioning year of the 351 with a known date), 92 came online in the past decade and the oldest still listed is Masjed Soleyman Oil Field (Iran), dating from 1908. 40+ projects are under construction or proposed, led by Iran-Hormoz nuclear power plant (5.0 GW).
