Plastiras is a 130 MW hydro power station in Thessaly, Greece. Based on reported annual generation of 180 GWh, it can supply roughly 51,457 homes. It ranks #32 of 90 Greece power plants by installed capacity. Commissioned in 1959, it is around 67 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 5.9% of Greece's electricity; the national grid averages 315 gCO₂/kWh (49.7% low-carbon) (2025).

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 39.2°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 12% 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: 56/100 — 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 #12 largest hydro power plant of 18 in Greece by capacity.
Greece has 18 hydro power plants in this dataset, together about 3,501 MW of capacity.
