Maroun is a 75 MW hydro power plant in Khuzestan, Iran. Based on its capacity (estimated), it can supply roughly 75,085 homes (estimated). It ranks #84 of 107 Iran power plants by installed capacity. Commissioned in 2004, it is around 22 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 3.3% of Iran's electricity; the national grid averages 660 gCO₂/kWh (5.7% low-carbon) (2025).

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a hot semi-arid steppe climate (Köppen BSh) — Northern Hemisphere, latitude 30.6°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 78% 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: 21/100 — 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.
