Derrybrien is a 60 MW wind power plant in Connaught, Ireland. It is operated by ESBI. Based on its capacity (estimated), it can supply roughly 51,058 homes (estimated). It ranks #26 of 64 Ireland power plants by installed capacity. Commissioned in 2006, it is around 20 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, wind supplies about 38.0% of Ireland's electricity; the national grid averages 257 gCO₂/kWh (48.1% low-carbon) (2025).

This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 53.1°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 29% 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: 67/100 — 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.
