At 201 MW, Kotmale is well above the median hydro plant in Sri Lanka (50 MW). Technically it is described as conventional storage. Its current lifecycle status is “Construction” — so it is not yet, or no longer, generating at full output. Hydropower converts the energy of falling or flowing water into electricity; output depends on rainfall and reservoir level, and large dams also provide grid balancing and storage.
