Hpa-an power station is a 1,280 MW coal power station in Kayin State, Myanmar. It is operated by TTCL PCL [100%]. Based on its capacity (estimated), it can supply roughly 1.6 million homes (estimated). It ranks #7 of 69 Myanmar power plants by installed capacity. Commissioned in 2023, it is around 3 years old — recently built. In context, coal supplies about 5.5% of Myanmar's electricity; the national grid averages 503 gCO₂/kWh (47.9% low-carbon) (2024).

At 1,280 MW, Hpa-an power station is well above the median coal plant in Myanmar (500 MW). Technically it is described as ultra-supercritical. 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.

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a tropical monsoon climate (Köppen Am) — Northern Hemisphere, latitude 16.9°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).
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 an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion 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.
The #5 largest coal power plant of 21 in Myanmar by capacity.
Myanmar has 21 coal power plants in this dataset, together about 17,010 MW of capacity.
