GasCaliforniaUnited States of AmericaCO₂ reported

Dynegy Moss Landing Power Plant Hybrid is a 1,398 MW gas power station in California, United States of America. It is operated by Dynegy -Moss Landing LLC. Based on reported annual generation of 5,221 GWh, it can supply roughly 1,491,657 homes. It ranks #176 of 9,833 United States of America power plants by installed capacity. Commissioned in 2002, it is around 24 years old — relatively modern. Its measured emissions of 2,027,036 t CO₂/yr (US EPA GHGRP) are equivalent to about 472,503 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 warm-summer Mediterranean climate (Köppen Csb) — Northern Hemisphere, latitude 36.8°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 40% 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: 34/100 — 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).
