CT GUARDO 2 is a 486 MW coal power station in Castille and Leon, Spain. It is operated by IBERDROLA GENERACION S.A.. Based on reported annual generation of 1,103 GWh, it can supply roughly 315,171 homes. It ranks #54 of 872 Spain power plants by installed capacity. Commissioned in 1984, it is around 42 years old — long-established. In context, coal supplies about 0.3% of Spain's electricity; the national grid averages 154 gCO₂/kWh (74.6% low-carbon) (2025).

This facility's annual emissions are roughly equivalent to:
Estimated, not measured: from reported annual generation × a typical coal emission factor (~1000 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a warm-summer Mediterranean climate (Köppen Csb) — Northern Hemisphere, latitude 42.8°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 27% 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: 66/100 — this site sits in the mid 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 #10 largest coal power plant of 17 in Spain by capacity.
Spain has 17 coal power plants in this dataset, together about 8,783 MW of capacity.
