Gas power plant in California, United States of America. Approximate location 34.1556, -118.2782.
GasCaliforniaUnited States of AmericaCO₂ reported
Grayson is a 301 MW gas power station in California, United States of America. It is operated by City of Glendale - (CA). Based on reported annual generation of 80 GWh, it can supply roughly 23,000 homes. It ranks #943 of 9,833 United States of America power plants by installed capacity. Commissioned in 1975, it is around 51 years old — an older, legacy facility. Its measured emissions of 28,343 t CO₂/yr (US EPA GHGRP) are equivalent to about 6,607 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 warm-summer Mediterranean climate (Köppen Csb) — Northern Hemisphere, latitude 34.2°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 80% 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: 20/100 — this site sits in the bottom 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 ~3% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).

The #576 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.
