Santa Maria De Garona nuclear power plant is a retired nuclear power station in Burgos, Spain. Its current lifecycle status is “Retired” — so it is not yet, or no longer, generating at full output. It ranks #63 of 899 Spain power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, nuclear supplies about 18.8% of Spain's electricity; the national grid averages 154 gCO₂/kWh (74.6% low-carbon) (2025).

In context: how this plant compares

At 466 MW, Santa Maria De Garona nuclear power plant is below the median nuclear plant in Spain (1,087 MW). Technically it is described as boiling water reactor. Its lifecycle status is Retired; it no longer generates electricity. Nuclear plants split uranium to raise steam with no direct CO₂; they run as steady baseload with very high capacity factors and the longest operating lifetimes of any thermal plant.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.
