Kaihua is a 5 MW hydro power plant in Lapland, Finland. It is operated by Rovakairan Tuotanto Oy. Based on its capacity (estimated), it can supply roughly 5,406 homes (estimated). It ranks #133 of 185 Finland power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 15.1% of Finland's electricity; the national grid averages 57 gCO₂/kWh (96.3% low-carbon) (2025).

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a subarctic (boreal) climate (Köppen Dfc) — Northern Hemisphere, latitude 66.3°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 162% 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: 99/100 — 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.

The #58 largest hydro power plant of 95 in Finland by capacity.
Finland has 95 hydro power plants in this dataset, together about 2,382 MW of capacity.
