Hanasaari B is a 212 MW coal power station in Uusimaa, Finland. It is operated by Helsingin Energia. Based on reported annual generation of 1,453 GWh, it can supply roughly 415,028 homes. It ranks #8 of 185 Finland power plants by installed capacity. In context, coal supplies about 0.2% of Finland's electricity; the national grid averages 57 gCO₂/kWh (96.3% low-carbon) (2025).

This facility's annual emissions are roughly equivalent to:
Estimated, not measured: from reported annual generation × a typical coal emission factor (~1000 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 60.2°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 87% 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: 91/100 — 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 #3 largest coal power plant of 5 in Finland by capacity.
Finland has 5 coal power plants in this dataset, together about 1,340 MW of capacity.
