Oil power plant in Alaska, United States of America. Approximate location 55.3574, -131.697.

OilAlaskaUnited States of AmericaCO₂ modelled

S W Bailey is a 25.9 MW oil power plant in Alaska, United States of America. It is operated by Ketchikan Public Utilities. Based on reported annual generation of 27 GWh, it can supply roughly 7.7k homes. It ranks #4393 of 10,884 United States of America power plants by installed capacity. Commissioned in 1982, it is around 44 years old — long-established. Its modelled annual emissions are 17,011 t CO₂/yr (Climate TRACE), equivalent to about 4.0k 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 25.9 MW, S W Bailey is well above the median oil plant in United States of America (7.2 MW). 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.

~17,011 t CO₂/yr (modelled) — in everyday terms

This facility's annual emissions are roughly equivalent to:

40kbarrels of crude oil burned
4.0kgasoline cars driven for a year
284ktree seedlings grown for 10 years

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 temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 55.4°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 65% 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: 85/100 — this site sits in the top 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

This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.
