Nihonkaisui Ako power station is a 55 MW other power plant in Hyogo, Japan. Based on its capacity (estimated), it can supply roughly 41k homes (estimated). It ranks #299 of 692 Japan power plants by installed capacity. Its modelled annual emissions are 12,222 t CO₂/yr (Climate TRACE), equivalent to about 2.8k cars driven for a year. In context, the national grid averages 477 gCO₂/kWh (32.7% low-carbon) (2025).

This other plant generates electricity for the grid. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 34.8°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 20% below 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: 43/100 — this site sits in the mid 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.
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
The #12 largest other power plant of 15 in Japan by capacity.
