[1] It is owned and operated by Energética Barra Grande SA (BAESA) and produces a 30% equivalent of the demand in Santa Catarina.

The dam impounds a reservoir with a surface area of 94 square kilometres (36 sq mi) which supplies water to three 236 MW Francis turbines in the power station.

[1] Construction of the dam required clearing 40 square kilometres (15 sq mi) of araucaria, a Brazilian pine tree, of which only 1% to 7% of their original forest survives.

The environmental controversy require BAESA to extend and acquire new licenses along with spending extra money on programs.
