Nova Avanhandava Dam, Hydroelectric power station in Buritama, Brazil.

Nova Avanhandava Dam is an embankment dam with gravity sections on the Tietê River, about 8.5 km southwest of Buritama in São Paulo state. Its 2,038 m-long concrete face has a row of square window openings and gated bays, with curved spillway gates releasing water on the right. A yellow gantry crane and four steel lattice towers stand along the crest.

The dam was completed in 1982, the same year its three Kaplan turbine-generators were commissioned, each rated at 115.8 MW for a total of 347.4 MW. Two ship locks were added in 1991 to handle the 29 m drop between the reservoir and the river downstream. The plant is owned and operated by AES Tietê.

The two ship locks, in use since 1991, let barges carrying grain and other cargo bypass the 29-metre drop and continue along the Tietê. The reservoir, flooding up to 210 km², also draws anglers and boaters to Buritama's stretch of the river.

The dam lies about 8.5 km southwest of Buritama, reached by road from the city; the crest is closed to visitors, so the concrete face, the yellow gantry crane and the spillway gates are seen from the banks and public roads. The two ship locks, in use since 1991, can be watched as vessels are raised or lowered through the 29 m drop.

The dam's two ship locks, in place since 1991, lift or lower vessels 29 metres between the reservoir and the river downstream, letting barges carrying grain and other freight continue along the Tietê. The locks sit beside the spillway gates that release surplus water.
