Dams were built in 1912 and 1941 to supply the town with hydro-electric power.
The falls have been harnessed for hydro-electric power since the beginning of the 20th century.
Since the early 20th century, the term is used almost exclusively in conjunction with the modern development of hydro-electric power.
In 2009 the park completed a restoration of the plant, and now runs entirely off hydro-electric power.
So our potential for hydro-electric and tidal power is, in fact, limited.
The dam was constructed in 1969 for irrigation and hydro-electric power.
The reservoir also contributes to generation of hydro-electric power to a small extent.
This water goes first to generate hydro-electric power and then to irrigate the land.
Today the levadas not only supply water to the southern parts of the island but provide hydro-electric power.
Due to their relatively large discharge, they are both exploited for the production of hydro-electric power.
