Nasudden is a 10 MW wind power plant in Gotland, Sweden. It is operated by 100% Vattenfall. Based on its capacity (estimated), it can supply roughly 8,679 homes (estimated). It ranks #144 of 168 Sweden power plants by installed capacity. Commissioned in 1983, it is around 43 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, wind supplies about 22.8% of Sweden's electricity; the national grid averages 35 gCO₂/kWh (98.8% low-carbon) (2025).

This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 57.1°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 63% 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: 84/100 — 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.
