Phillips 66 Rodeo Refinery — United States of America

Gas power plant in California, United States of America. Approximate location 38.0417, -122.2583.

GasCaliforniaUnited States of AmericaCO₂ modelled

Phillips 66 Rodeo Refinery is a 54.9 MW gas power plant in California, United States of America. It is operated by Phillips 66 Company. Based on reported annual generation of 389 GWh, it can supply roughly 111k homes. It ranks #3534 of 10,884 United States of America power plants by installed capacity. Commissioned in 1986, it is around 40 years old — long-established. Its modelled annual emissions are 79,773 t CO₂/yr (Climate TRACE), equivalent to about 19k cars driven for a year. In context, gas supplies about 40.0% 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 54.9 MW, Phillips 66 Rodeo Refinery is below the median gas plant in United States of America (121.2 MW). 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.

~79,773 t CO₂/yr (modelled) — in everyday terms

This facility's annual emissions are roughly equivalent to:

1.5kmillion cubic feet of natural gas burned
17khomes' electricity use for a year
80kacres of US forest absorbing CO₂ for a year
0.01%of the CO₂ from all United States of America power plants with an emissions figure in PowerAtlas

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 warm-summer Mediterranean climate (Köppen Csb) — Northern Hemisphere, latitude 38.0°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 45% below 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: 31/100 — this site sits in the bottom 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

This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with marine corrosion the leading environmental stress.
