United States — Energy Infrastructure

OverWatts maps 7,788 energy assets in United States across 16 layers — the 2nd-largest mapped base of 157 countries. They include 3,831 power plants, 1,894 oil & gas fields and 620 pipelines. Operating generation capacity is 1168 GW, led by gas at 47%. Refining capacity is about 8,236 kb/d.

The companies named on the most assets are NextEra Energy Inc (177), Invenergy LLC (72) and EDF Renewables (69), counting both ownership and operatorship. Half of United States's mapped assets in service predate 2003 (median commissioning year of the 4,298 with a known date), 1,246 came online in the past decade and the oldest still listed is Midway-Sunset - Aera Energy (Unconventional) Oil and Gas Asset (California, United States), dating from 1901. 40+ projects are under construction or proposed, led by Fermi America Project Matador power station (6.0 GW).
