In context: how this plant compares

At 1.3 MW, AT&T Holger is below the median gas plant in United States of America (121.2 MW). Technically it is described as Engine. 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.
