HydroDiyalaIraq

Hemrin Dam is a 50 MW hydro power plant in Diyala, Iraq. It is operated by Iraq's Ministry of Water Resources. Based on its capacity (estimated), it can supply roughly 50,057 homes (estimated). It ranks #27 of 28 Iraq power plants by installed capacity. Commissioned in 1981, it is around 45 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 1.3% of Iraq's electricity; the national grid averages 683 gCO₂/kWh (1.6% low-carbon) (2024).

Local climate & thermal context

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 34.1°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 73% 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: 22/100 — 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.
