Geothermal power plant in Aydin, Turkey. Approximate location 37.8845, 27.6304.

GeothermalAydinTurkey

Galip Hoca Germencik is a 47 MW geothermal power plant in Aydin, Turkey. It is operated by Güriş Holding. Based on its capacity (estimated), it can supply roughly 88k homes (estimated). It ranks #355 of 502 Turkey power plants by installed capacity. Commissioned in 2009, it is around 17 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, geothermal supplies about 3.0% of Turkey's electricity; the national grid averages 475 gCO₂/kWh (43.3% low-carbon) (2025).

In context: how this plant compares

At 47 MW, Galip Hoca Germencik is well above the median geothermal plant in Turkey (34 MW). Geothermal plants tap underground heat to raise steam for a turbine; they provide steady, low-carbon baseload but are limited to geologically active regions.

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

Local climate & thermal context

This geothermal plant taps underground heat to raise steam that drives a turbine. It sits in a hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 37.9°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 46% 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: 31/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.

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.
