Harry D Mattison Gas Plant is a 349 MW gas power station in Arkansas, United States of America. It ranks #1526 of 10,938 United States of America power plants by installed capacity. Commissioned in 2007, it is around 19 years old — relatively modern. Its annual emissions of 120,648 t CO₂/yr (US EPA GHGRP) are equivalent to about 28k 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).

At 349 MW, Harry D Mattison Gas Plant is well above the median gas plant in United States of America (121.2 MW). Technically it is described as OCGT. Its current lifecycle status is “Mothballed” — 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.
