Air Products Port Arthur — United States of America

Air Products Port Arthur is a 169.1 MW gas power station in Texas, United States of America. It ranks #2195 of 10,938 United States of America power plants by installed capacity. Its modelled annual emissions are 249,960 t CO₂/yr (Climate TRACE), equivalent to about 58k 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).

In context: how this plant compares

At 169.1 MW, Air Products Port Arthur is well above the median gas plant in United States of America (121.2 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG); Mitsubishi Heavy Industries: 501JAC. Its current lifecycle status is “Pre Construction” — so it is not yet, or no longer, generating at full output. Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.
