Coal power plant in Kanchanaburi, Thailand. Approximate location 13.944207, 99.711134.

CoalKanchanaburiThailandsubcritical

Wang Sala Mill power station is a 34 MW coal power plant in Kanchanaburi, Thailand. It is operated by Thai Kraft Paper Industry Co Ltd [100%]. Based on its capacity (estimated), it can supply roughly 43k homes (estimated). It ranks #97 of 238 Thailand power plants by installed capacity. Commissioned in 1996, it is around 30 years old — long-established. In context, coal supplies about 17.8% of Thailand's electricity; the national grid averages 546 gCO₂/kWh (16.6% low-carbon) (2025).

In context: how this plant compares

At 34 MW, Wang Sala Mill power station is below the median coal plant in Thailand (660 MW). Technically it is described as subcritical. Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.

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

Climate zone & how it works

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a tropical savanna climate (Köppen Aw) — Northern Hemisphere, latitude 13.9°N — which shapes how much energy it can produce and how its output varies through the year.

Site climate & environmental severity

For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness the leading environmental stress.

Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.

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.
