Summa tv is a 12 MW wind power plant in Kymenlaakso, Finland. It is operated by Haminan Energia. Based on its capacity (estimated), it can supply roughly 10,211 homes (estimated). It ranks #106 of 185 Finland power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, wind supplies about 27.4% of Finland's electricity; the national grid averages 57 gCO₂/kWh (96.3% low-carbon) (2025).

This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 60.6°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 82% 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: 90/100 — 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.
