Gas power plant in Munster, Ireland. Approximate location 52.6324, -9.0596.

GasMunsterIrelandCO₂ reported

Sealrock (Aughinish CHP) is a 166 MW gas power station in Munster, Ireland. It is operated by Aughinish. Based on its capacity (estimated), it can supply roughly 186,963 homes (estimated). It ranks #13 of 64 Ireland power plants by installed capacity. Its measured emissions of 274,930 t CO₂/yr (Climate TRACE) are equivalent to about 64,086 cars driven for a year. In context, gas supplies about 48.4% of Ireland's electricity; the national grid averages 257 gCO₂/kWh (48.1% low-carbon) (2025).

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 temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 52.6°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 13% 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: 57/100 — this site sits in the mid 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).
