Koskensaari is a 1 MW oil power plant in Southern Savonia, Finland. It is operated by Helsingin Rauta Oy. Based on its capacity (estimated), it can supply roughly 901 homes (estimated). It ranks #181 of 185 Finland power plants by installed capacity. In context, oil supplies about 2.3% 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 installed capacity at a typical 30% load factor × a typical oil emission factor (~750 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a subarctic (boreal) climate (Köppen Dfc) — Northern Hemisphere, latitude 61.8°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 109% 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: 95/100 — 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 #11 largest oil power plant of 11 in Finland by capacity.
Finland has 11 oil power plants in this dataset, together about 859 MW of capacity.
