In context: how this plant compares

At 1,442 MW, Himeji Daiichi 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: not found. 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.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

~1,891,000 t CO₂/yr (modelled) — in everyday terms

This facility's annual emissions are roughly equivalent to:

441kpassenger cars driven for a year
247khomes' yearly energy use
32 milliontree seedlings grown 10 years to absorb it

Equivalencies via US EPA Greenhouse Gas Equivalencies; modelled emissions from Climate TRACE.
