Dublin Bay Power

Gas power plant in Leinster, Ireland. Approximate location 53.34, -6.2049.

GasLeinsterIrelandOCGTCO₂ modelled

Dublin Bay Power is a 405 MW gas power station in Leinster, Ireland. It is operated by Synergen. Based on reported annual generation of 3,019 GWh, it can supply roughly 862k homes. It ranks #9 of 76 Ireland power plants by installed capacity. Commissioned in 2002, it is around 24 years old — relatively modern. Its modelled annual emissions are 467,830 t CO₂/yr (Climate TRACE), equivalent to about 109k 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).

In context: how this plant compares

At 405 MW, Dublin Bay Power is well above the median gas plant in Ireland (275 MW). Technically it is described as OCGT. Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

~467,830 t CO₂/yr (modelled) — in everyday terms

This facility's annual emissions are roughly equivalent to:

109kpassenger cars driven for a year
61khomes' yearly energy use
7.8 milliontree seedlings grown 10 years to absorb it

Equivalencies via US EPA Greenhouse Gas Equivalencies; modelled emissions from Climate TRACE.

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 53.3°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 25% 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: 64/100 — this site sits in the mid third of the power plants we cover by heating degree-days.

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

Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.

Site climate & environmental severity

For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with marine corrosion the leading environmental stress.

Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.

Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
