ENGIE Commissions 753 MW Assú Sol, Its Largest Solar Complex Globally

ENGIE has fully commissioned the 753 MW Assú Sol photovoltaic complex in Assú, marking the Group’s largest operational solar park worldwide. Approval from Brazilian authorities was secured on February 13, 2026, following the completion of works in December 2025, with a total investment of R$3.3 billion.

Located on a 2,344-hectare site in the state of Rio Grande do Norte, northeastern Brazil, the complex comprises 16 solar parks and is expected to generate enough electricity annually to meet the needs of approximately 850,000 people. The project features more than 1.5 million photovoltaic modules, 12,000 km of cabling, and 53 km of internal access roads.

Constructed over a 30-month period, the large-scale industrial project was delivered on schedule and within budget, adhering to strict safety standards. More than 4,500 direct jobs were created during the construction phase. The development incorporated advanced technologies, including drone-based aerial mapping, automated graders integrated with 3D modelling systems, and the first deployment in Brazil of an automated pile driver dedicated to solar installations. These innovations enhanced construction precision, efficiency, and environmental performance.

Beyond energy generation, ENGIE highlighted its commitment to local development in the Assú region. Community initiatives undertaken as part of the project include the construction of a school and health centre, development of multi-sports facilities, improvements to water access, and donations of agricultural equipment.

Assú Sol further strengthens ENGIE’s footprint in Brazil, where the company operates 15.7 GW of installed capacity, all from renewable sources, including hydroelectric, onshore wind, and solar assets. The Group also manages 3,200 km of transmission lines and 22 substations nationwide.

In December 2025, ENGIE also commissioned the 846 MW Serra do Assuruá wind farm in Bahia, now its largest onshore wind facility globally. Additionally, the company energised the first 334 km section of the Asa Branca transmission network in Bahia, part of a broader 1,000 km project spanning Bahia, Minas Gerais, and Espírito Santo. Construction is ongoing on the remaining 660 km, alongside the development of the 780 km Graúna transmission project between Paraná and Santa Catarina.

Paulo Almirante, Deputy Chief Executive Officer of ENGIE in charge of Renewable & Flexible Power activities, said the commissioning of Assú Sol demonstrates the company’s capability to deliver large-scale renewable projects efficiently and in alignment with its renewable growth strategy in Brazil and internationally.
