Thisvi Power Station is a 420 MW gas power station in Central Greece, Greece. It is operated by Elpedison Energy. Based on reported annual generation of 1,245 GWh, it can supply roughly 356k homes. It ranks #21 of 99 Greece power plants by installed capacity. Commissioned in 2010, it is around 16 years old — relatively modern. Its annual emissions of 316,607 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 74k cars driven for a year. In context, gas supplies about 38.4% of Greece's electricity; the national grid averages 315 gCO₂/kWh (49.7% low-carbon) (2025).

In context: how this plant compares
At 420 MW, Thisvi Power Station is around the median gas plant in Greece (444 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG); Ansaldo Energia: 94.3A4. Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.

Local climate & thermal context
This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 38.2°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 25% 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: 41/100 — this site sits in the mid third of the power plants we cover by heating degree-days.
A gas turbine here also runs ~0% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.
Site climate & environmental severity
This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
