In context: how this plant compares
At 360 MW, AGUAYO 3 is well above the median hydro plant in Spain (55.2 MW). Technically it is described as pumped storage. Its current lifecycle status is “Pre 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.
