DC Water CHP

Biomass power plant in Maryland, United States of America. Approximate location 38.8206, -77.0183.

BiomassMarylandUnited States of AmericaCO₂ reported

DC Water CHP is a 14 MW biomass power plant in Maryland, United States of America. It is operated by DC Water. Based on reported annual generation of 55 GWh, it can supply roughly 15,742 homes. It ranks #4189 of 9,833 United States of America power plants by installed capacity. Commissioned in 2015, it is around 11 years old — relatively modern. Its measured emissions of 31,907 t CO₂/yr (Climate TRACE) are equivalent to about 7,438 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).

Local climate & thermal context

This biomass plant burns organic material (wood, residues) to raise steam for a turbine. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 38.8°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 5% 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: 48/100 — this site sits in the mid 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.
