The Central Hidroeléctrica da Fajã do Redondo (hydroelectric power plant) came into operation in 1927 at the service of the Ponta Delgada City Council and was intended to reinforce the electricity supply to the city of Ponta Delgada. Closed since 2004, the imposing masonry building is currently part of the museum circuit of the island of São Miguel.

Access to the Fajã Redonda hydroelectric power plant is via a pedestrian trail, in an environment of great natural beauty.
