Feeding Capacity
580,000 homes
The Acauã Wind Complex, inaugurated on May 21, 2024, is composed of the Acauã I, II and III Wind Power Plants with a total of 26 wind turbines and a capacity of 4.2 MW each, arranged in four wind farms, distributed in the municipalities of Santana do Matos, Lagoa Nova, São Vicente and Tenente Laurentino Cruz, in the state of Rio Grande do Norte.
The installed capacity is 109.2 MW, with enough energy to supply about 580 thousand homes in the average consumption pattern of the Northeast. The construction of the Acauã Wind Complex had an investment of approximately R$ 700 million and generated more than 800 jobs since the beginning of the implementation, a very significant part of which was occupied by residents of Rio Grande do Norte.
The full commercial operation of the Acauã Wind Complex began on July 6, 2024.

Wind turbines
The wind turbines of the Santo Inácio Wind Complex and the Gravier Wind Power Plant are of the type with a horizontal axis. Its structure is inspired by windmills and wind vanes, chosen by Aliança for having greater efficiency in energy generation than the other alternative, with a vertical axis.
Nacelle
It is the heaviest structure of the wind turbine, where the rotor and the blades are attached to it. It is located at the top of the tower and receives the main components such as the gearbox, the generator, the chassis and the yaw (responsible for electronic control) and hydraulic systems, in addition to the brakes, clutch and bearings
Transmission Lines
The energy produced at CESI and Gravier is interconnected to the SIN – National Interconnected System – through CHESF’s substation (SE), Mossoró IV, via a 9 km 230 kV transmission line.
Tower
The largest component of the wind turbine, responsible for supporting the rotor, nacelle and blades. At the Santo Inácio Wind Complex and at the Gravier Wind Power Plant, the wind turbine towers are built in concrete.
Paddles
They are responsible for capturing the mechanical energy of the wind, converting its power to the rotor. The structure of the blades is made with materials such as plastic – mainly epoxy and polyester – and fiberglass.
