Lielahti is a 142 MW gas power station in Pirkanmaa, Finland. It is operated by Tampereen Sähkölaitos. Based on its capacity (estimated), it can supply roughly 159,932 homes (estimated). It ranks #18 of 185 Finland power plants by installed capacity. In context, gas supplies about 1.2% of Finland's electricity; the national grid averages 57 gCO₂/kWh (96.3% low-carbon) (2025).

~223,906 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

52,192passenger cars driven for a year
29,200homes' yearly energy use
3,731,760tree seedlings grown 10 years to absorb it

Estimated, not measured: from installed capacity at a typical 45% load factor × a typical gas emission factor (~400 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

Local climate & thermal context

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a subarctic (boreal) climate (Köppen Dfc) — Northern Hemisphere, latitude 61.5°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 108% 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.

A gas turbine here also runs ~0% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
