In context: how this plant compares
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.
