Canada — Energy Infrastructure
OverWatts maps 1,896 energy assets in Canada across 14 layers — the 4th-largest mapped base of 157 countries. They include 1,165 oil & gas fields, 452 power plants and 88 pipelines. Operating generation capacity is 137 GW, led by hydro at 56%. Refining capacity is about 1,130 kb/d.
The companies named on the most assets are Hydro Quebec (50), Canadian Natural Resources (45) and Ontario Power Generation Inc (36), counting both ownership and operatorship. Half of Canada's mapped assets in service predate 1971 (median commissioning year of the 1,325 with a known date), 98 came online in the past decade and the oldest still listed is Algoma steel plant, dating from 1901. 40+ projects are under construction or proposed, led by Gull Island hydroelectric plant (2.3 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.
