São Gonçalo Solar Project

São Gonçalo Solar Project

The São Gonçalo solar facility in the state of Piauí is a record-breaking project consisting of more than 2.2 million solar panels. It is also playing a key role in Brazil’s green recovery.

About the plant

Brazil’s record-breaking solar facility

Located in Brazil’s semiarid region, in the state of Piauí, the São Gonçalo (SGL) solar facility is a record-breaking project consisting of more than 2.2 million solar panels. It is the largest solar plant currently under construction in South America.

The construction of São Gonçalo’s first 475 MW section started in October 2018 and was connected to the grid in January 2020. In August 2019, Enel announced the start of construction of the 133 MW extension of the solar park, which is also up and running. In addition, Enel Green Power is working on the second extension of the plant, with an installed capacity of 256 MW. This will bring its overall capacity up to 864 MW.

The whole complex covers an area of around 12,000,000 m², the equivalent of approximately 1,500 soccer stadiums.

Timeline

Milestones

Given the size of the project, Enel Green Power has designed an innovative plant layout based on a high-resolution resource assessment to optimize its energy output. In addition, Enel Green Power is using a variety of innovative tools and methods, such as proximity sensors on machinery to boost site safety, bifacial solar modules, a substation with digital technologies, drones for topographic survey, as well as advanced digital platforms and software solutions to monitor and remotely support site activities and plant commissioning. These processes and tools enable swifter, more accurate and reliable data collection, thereby improving the quality of construction and facilitating communication between on-site and off-site teams.
