United Kingdom — Energy Infrastructure
OverWatts maps 750 energy assets in United Kingdom across 15 layers — the 10th-largest mapped base of 157 countries. They include 320 oil & gas fields, 305 power plants and 36 pipelines. Operating generation capacity is 67.5 GW, led by gas at 51%. Refining capacity is about 1,171 kb/d.
The companies named on the most assets are Harbour Energy PLC (45), Shell (45) and Neo Energy Ltd (36), counting both ownership and operatorship. Half of United Kingdom's mapped assets in service predate 2001 (median commissioning year of the 377 with a known date), 74 came online in the past decade and the oldest still listed is Tata Steel Port Talbot steel plant, dating from 1905. 40+ projects are under construction or proposed, led by Hornsea wind farm (5.6 GW).
Operating generation capacity by fuel
Utility-scale sites of 100 MW and above. Distributed generation — rooftop solar especially — is outside the tracker, so this runs below national installed capacity.
