Samarra Barrage is a 75 MW hydro power plant in Salah ad Din Governorate, Iraq. It is operated by Iraq's Ministry of Water Resources. Based on its capacity (estimated), it can supply roughly 75,085 homes (estimated). It ranks #25 of 28 Iraq power plants by installed capacity. Commissioned in 1956, it is around 70 years old — an older, legacy facility. 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).

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 34.2°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.
