Ratchaburi World cogeneration power station is a 234 MW gas power station in Ratchaburi, Thailand. It is operated by Thai World Power Co Ltd [60%]; RATCH Group PCL [40%]. Based on its capacity (estimated), it can supply roughly 264k homes (estimated). It ranks #58 of 238 Thailand power plants by installed capacity. Commissioned in 2015, it is around 11 years old — relatively modern. In context, gas supplies about 65.5% of Thailand's electricity; the national grid averages 546 gCO₂/kWh (16.6% low-carbon) (2025).

In context: how this plant compares
At 234 MW, Ratchaburi World cogeneration power station is around the median gas plant in Thailand (256 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG). 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.

Climate zone & how it works
This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a tropical savanna climate (Köppen Aw) — Northern Hemisphere, latitude 13.7°N — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
Site climate & environmental severity
This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness the leading environmental stress.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
