Plant No 2 Orange County

Biomass power plant in California, United States of America. Approximate location 33.6433, -117.9556.

BiomassCaliforniaUnited States of AmericaCO₂ modelled

Plant No 2 Orange County is a 16 MW biomass power plant in California, United States of America. It is operated by Orange County Sanitation Dist. Based on reported annual generation of 53 GWh, it can supply roughly 15k homes. It ranks #5115 of 10,938 United States of America power plants by installed capacity. Commissioned in 1993, it is around 33 years old — long-established. Its modelled annual emissions are 21,796 t CO₂/yr (Climate TRACE), equivalent to about 5.1k cars driven for a year. In context, biomass supplies about 1.0% 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 16 MW, Plant No 2 Orange County is below the median biomass plant in United States of America (18 MW). Biomass plants burn organic material such as wood, residues or waste-derived fuel to raise steam; they are dispatchable and counted as low-carbon where the feedstock is sustainably sourced.

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

~21,796 t CO₂/yr (modelled) — in everyday terms

This facility's annual emissions are roughly equivalent to:

5.1kpassenger cars driven for a year

Local climate & thermal context

This biomass plant burns organic material (wood, residues) to raise steam for a turbine. It sits in a hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 33.6°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 72% 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: 23/100 — this site sits in the bottom 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 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.
