Croydon CT Generating Station

Oil power plant in Pennsylvania, United States of America. Approximate location 40.08, -74.8917.

OilPennsylvaniaUnited States of AmericaOCGTCO₂ modelled

Croydon CT Generating Station is a 546 MW oil power station in Pennsylvania, United States of America. It is operated by Exelon Power. Based on reported annual generation of 3 GWh, it can supply roughly 742 homes. It ranks #1214 of 10,938 United States of America power plants by installed capacity. Commissioned in 1974, it is around 52 years old — an older, legacy facility. Its modelled annual emissions are 1,361 t CO₂/yr (Climate TRACE), equivalent to about 317 cars driven for a year. In context, oil supplies about 0.7% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

In context: how this plant compares

At 546 MW, Croydon CT Generating Station is well above the median oil plant in United States of America (7 MW). Technically it is described as OCGT. Oil-fired plants burn heavy fuel oil or diesel, usually as peaking or backup capacity on islands and grids without gas pipelines; high fuel cost keeps their utilisation low.

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

~1,361 t CO₂/yr (modelled) — in everyday terms

This facility's annual emissions are roughly equivalent to:

317passenger cars driven for a year
177homes' yearly energy use
23ktree seedlings grown 10 years to absorb it

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

Local climate & thermal context

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 40.1°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 8% 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: 53/100 — this site sits in the mid third of the power plants we cover by heating degree-days.

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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness 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.
