Marcus Hook Energy LP is a 836 MW gas power station in Pennsylvania, United States of America. It is operated by Marcus Hook Energy LP. Based on reported annual generation of 4,470 GWh, it can supply roughly 1,277,257 homes. It ranks #399 of 9,833 United States of America power plants by installed capacity. Commissioned in 2005, it is around 21 years old — relatively modern. Its measured emissions of 2,235,379 t CO₂/yr (US EPA GHGRP) are equivalent to about 521,067 cars driven for a year. In context, gas supplies about 40.0% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 39.8°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 5% above 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: 52/100 — 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.
A gas turbine here also runs ~0% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).

The #194 largest gas power plant of 1818 in United States of America by capacity.
United States of America has 1818 gas power plants in this dataset, together about 546,436 MW of capacity.
