Local climate & thermal context

This storage plant stores and releases electricity (pumped-hydro or batteries) to balance the grid. It sits in a subarctic (boreal) climate (Köppen Dfc) — Northern Hemisphere, latitude 64.8°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 211% 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: 100/100 — this site sits in the top third of the power plants we cover by heating degree-days.

Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.

Site climate & environmental severity

This site sits in a benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with thermal cycling the leading environmental stress.
