Ywama is a 292 MW gas power station in Yangon, Myanmar. It is operated by UPP Power (Myanmar) Ltd [100%]. Based on reported annual generation of 238 GWh, it can supply roughly 68k homes. It ranks #27 of 69 Myanmar power plants by installed capacity. Commissioned in 2014, it is around 12 years old — relatively modern. In context, gas supplies about 46.1% of Myanmar's electricity; the national grid averages 503 gCO₂/kWh (47.9% low-carbon) (2024).

Known, modelled and calculated values are kept separate. Missing fields are shown as unavailable.
Capacity provenance
The public capacity above is the current source-record value. A 2026 tracker candidate lists 292 MW for Ywama power station, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).

In context: how this plant compares
At 292 MW, Ywama is well above the median gas plant in Myanmar (172.2 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG); GE Power: 6F.03, Siemens Energy: SGT5-2000E. 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.

Local climate & thermal context
This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. 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.
Monthly mean temperature
This site has effectively no heating season (tropical/equatorial climate), so winter heat loss is not the driver here. The thermal concern shifts to year-round process heat and humidity/heat-driven corrosion of hot equipment.
A gas turbine here also runs ~9% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.
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.
