Stephenville is a 54 MW gas power plant in Newfoundland and Labrador, Canada. It is operated by NB Power. Based on its capacity (estimated), it can supply roughly 60,819 homes (estimated). It ranks #362 of 1,159 Canada power plants by installed capacity. Commissioned in 1948, it is around 78 years old — an older, legacy facility. In context, gas supplies about 17.8% of Canada's electricity; the national grid averages 191 gCO₂/kWh (77.0% low-carbon) (2025).

This facility's annual emissions are roughly equivalent to:
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.

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 48.5°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.
A gas turbine here also runs ~0% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).

The #73 largest gas power plant of 75 in Canada by capacity.
Canada has 75 gas power plants in this dataset, together about 19,786 MW of capacity.
