Gara Chilar is a 130 MW hydro power station in Zangilan Rayon, Iran. It is operated by Iran Water and Power Resources Development Company. Based on its capacity (estimated), it can supply roughly 130,148 homes (estimated). It ranks #72 of 107 Iran power plants by installed capacity. Commissioned in 2015, it is around 11 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-summer humid continental climate (Köppen Dfa) — Northern Hemisphere, latitude 38.9°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 45% 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: 77/100 — this site sits in the top 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.
