Oil power plant in Maryland, United States of America. Approximate location 39.2986, -76.5636.
OilMarylandUnited States of AmericaCO₂ reported
Philadelphia is a 83 MW oil power plant in Maryland, United States of America. It is operated by Constellation Power Source Gen. Based on reported annual generation of 2 GWh, it can supply roughly 514 homes. It ranks #2173 of 9,833 United States of America power plants by installed capacity. Commissioned in 1970, it is around 56 years old — an older, legacy facility. Its measured emissions of 54,381 t CO₂/yr (Climate TRACE) are equivalent to about 12,676 cars driven for a year. In context, oil supplies about 0.7% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 39.3°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 6% 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.
