Castlelost Flexgen power station is a 55 MW gas power plant in Leinster, Ireland. It is operated by Lumcloon Energy Ltd. Based on its capacity (estimated), it can supply roughly 61,945 homes (estimated). It ranks #30 of 64 Ireland power plants by installed capacity. Its measured emissions of 88,944 t CO₂/yr (Climate TRACE) are equivalent to about 20,733 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).

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 53.4°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 26% 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: 65/100 — 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).

The #12 largest gas power plant of 13 in Ireland by capacity.
Ireland has 13 gas power plants in this dataset, together about 3,807 MW of capacity.
