TIHANGE 3 is a 2,054 MW nuclear power station in Wallonia, Belgium. It is operated by Engie (Electrabel / BE-NUC). Based on reported annual generation of 17,896 GWh, it can supply roughly 5,113,085 homes. It ranks #2 of 75 Belgium power plants by installed capacity. Commissioned in 1985, it is around 41 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, nuclear supplies about 33.1% of Belgium's electricity; the national grid averages 150 gCO₂/kWh (72.0% low-carbon) (2025).

This nuclear plant uses heat from nuclear fission to raise steam for a turbine-generator. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 50.5°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 31% above the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.
Climate heat-demand index: 69/100 — this site sits in the top third of the power plants we cover by heating degree-days.
In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.

The #2 largest nuclear power plant of 3 in Belgium by capacity.
Belgium has 3 nuclear power plants in this dataset, together about 5,926 MW of capacity.
