BiomassCaliforniaUnited States of America

Caltech Central is a 1 MW biomass power plant in California, United States of America. It is operated by Bloom Energy 2009 PPA. Based on reported annual generation of 8 GWh, it can supply roughly 2,200 homes. It ranks #9223 of 9,833 United States of America power plants by installed capacity. Commissioned in 2010, it is around 16 years old — relatively modern. 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).

Local climate & thermal context

This biomass plant burns organic material (wood, residues) to raise steam for a turbine. It sits in a warm-summer Mediterranean climate (Köppen Csb) — Northern Hemisphere, latitude 34.1°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 77% 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: 21/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.

In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.
