In context: how this plant compares
At 1,950 MW, Chiba-Sodegaura power station is well above the median gas plant in Japan (847.4 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG); Mitsubishi Power: M701JAC. 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.
