Kızıldere (Zorlu) is a 15 MW geothermal power plant in Denizli, Turkey. It is operated by MB Holding. Based on its capacity (estimated), it can supply roughly 28,157 homes (estimated). It ranks #200 of 278 Turkey power plants by installed capacity. 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).

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.
Monthly mean temperature
Heating degree-days here run 41% 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: 33/100 — this site sits in the bottom 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.
