BiomassCaliforniaUnited States of America

WWTP Power Generation Station is a 7 MW biomass power plant in California, United States of America. It is operated by East Bay Municipal Util Dist. Based on reported annual generation of 21 GWh, it can supply roughly 6,000 homes. It ranks #5223 of 9,833 United States of America power plants by installed capacity. Commissioned in 1985, it is around 41 years old — long-established. 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 37.8°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 52% 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: 28/100 — 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.
