Allal Al Fassi is a 240 MW hydro power station in Fes-Boulemane, Morocco. It is operated by Office National de l\'Electricite (ONE). Based on its capacity (estimated), it can supply roughly 240,274 homes (estimated). It ranks #11 of 45 Morocco power plants by installed capacity. Commissioned in 1994, it is around 32 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 2.0% of Morocco's electricity; the national grid averages 596 gCO₂/kWh (24.0% low-carbon) (2025).

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 33.9°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 53% 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: 28/100 — 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.
