Climate zone & how it works

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 66.7°N — which shapes how much energy it can produce and how its output varies through the year.
