Megalopoli power station is a 600 MW coal power station in Peloponnese, Greece. It is operated by PPC. Based on reported annual generation of 2,904 GWh, it can supply roughly 829,714 homes. It ranks #7 of 90 Greece power plants by installed capacity. Commissioned in 1979, it is around 47 years old — long-established. In context, coal supplies about 4.7% of Greece's electricity; the national grid averages 315 gCO₂/kWh (49.7% 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 hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 37.4°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 10% below 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: 46/100 — 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 #5 largest coal power plant of 6 in Greece by capacity.
Greece has 6 coal power plants in this dataset, together about 4,995 MW of capacity.
