Mawella Coal Power Development Project is a 600 MW coal power station in Hambantota, Sri Lanka. It is operated by Ceylon Electricity Board; NTPC Ltd. Based on its capacity (estimated), it can supply roughly 751k homes (estimated). It ranks #6 of 55 Sri Lanka power plants by installed capacity. In context, coal supplies about 27.5% of Sri Lanka's electricity; the national grid averages 329 gCO₂/kWh (61.6% low-carbon) (2025).

In context: how this plant compares
At 600 MW, Mawella Coal Power Development Project is below the median coal plant in Sri Lanka (1,200 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 rainforest climate (Köppen Af) — Northern Hemisphere, latitude 6.0°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 an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion 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.
How it compares & nearby plants
The #6 largest coal power plant of 6 in Sri Lanka by capacity.
Sri Lanka has 6 coal power plants in this dataset, together about 6,200 MW of capacity.
