Sutter Energy Center

Gas power plant in California, United States of America. Approximate location 39.0531, -121.6959.

GasCaliforniaUnited States of AmericaCCGT · HRSGCO₂ measured

Sutter Energy Center is a 636 MW gas power station in California, United States of America. It is operated by Calpine Corp-Sutter. Based on reported annual generation of 653 GWh, it can supply roughly 187k homes. It ranks #1056 of 10,938 United States of America power plants by installed capacity. Commissioned in 2001, it is around 25 years old — relatively modern. Its annual emissions of 841,348 t CO₂/yr (US EPA GHGRP) are equivalent to about 196k 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 636 MW, Sutter Energy Center is well above the median gas plant in United States of America (121 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG). 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.

841,348 t CO₂/yr — in everyday terms

This facility's annual emissions are roughly equivalent to:

196kpassenger cars driven for a year
110khomes' yearly energy use
14 milliontree seedlings grown 10 years to absorb it

Equivalencies via US EPA Greenhouse Gas Equivalencies; emissions per US EPA GHGRP (measured for US EPA/EU ETS, modelled for 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 hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 39.1°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 50% 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: 29/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.

A gas turbine here also runs ~1% 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 mild atmospheric environment (estimated ISO 9223 class C2 — Low), 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.
