In context: how this plant compares
At 801 MW, Caledonia 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 “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.
