Furthermore, the plant has five skids of 1 MW, with a total area of 356 square meters, It is three cabins measurement area with a total area of 337 square meters.

A full completion of the works is scheduled for the end of 2025, with the delivery of other 75 MW of renewable energy and investment of R$ 450 million.

Billings Project

According to an article published by Canal Solar, on January 18 of this year, when the Opening from the first step project implementation, the initial investment in the plant was R$ 30 million

O São Paulo government considers the power plant as one of the main projects of development of sustainable energy and is being implemented under the coordination of SEMIL (Secretariat of Environment, Infrastructure and Logistics).

“The project is very interesting because we are taking advantage of the water surface to generate energy. We have the first photovoltaic plant floating what will generate energy commercially in Brazil”, said governor Tarcísio de Freitas, on the day of the plant’s inauguration.
