GasMassachusettsUnited States of AmericaCO₂ reported

Dighton Power Plant is a 200 MW gas power station in Massachusetts, United States of America. It is operated by Dighton Power LLC. Based on reported annual generation of 270 GWh, it can supply roughly 77,085 homes. It ranks #1257 of 9,833 United States of America power plants by installed capacity. Commissioned in 1999, it is around 27 years old — long-established. Its measured emissions of 151,449 t CO₂/yr (US EPA GHGRP) are equivalent to about 35,303 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).

Local climate & thermal context

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 41.8°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 29% 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: 67/100 — this site sits in the top 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).
