Brazil inaugurates GNA II, the largest thermal power station in Latin America. With 3 GW capacity and hydrogen-ready technology, the project marks a major step in Brazil’s energy transition.
Rio de Janeiro, July 28, 2025: Brazil has marked a historic milestone in its energy sector with the inauguration of GNA II, the largest thermal power station in Latin America. President Luiz Inácio Lula da Silva officially opened the facility at the Port of Açu in Rio de Janeiro State, highlighting the country’s growing potential in the global energy transition.
A Landmark Project in Brazil’s Energy Transition
GNA II is part of Brazil’s largest natural gas-based energy complex, representing a total investment of 7 billion reals (approximately US$1.33 billion). With an installed capacity of 3 gigawatts (GW), the plant will be capable of supplying electricity to nearly 8 million households.
The power station is equipped with a high-efficiency combined cycle system, enabling reduced fuel consumption and lower carbon emissions. Notably, GNA II is designed to use up to 50% hydrogen as a substitute for natural gas, making it a critical component of Brazil’s long-term clean energy goals.
A Strategic Initiative Under Brazil’s Growth Acceleration Programme (PAC)
The project has been included in the Growth Acceleration Programme (PAC) as one of the country’s strategic infrastructure initiatives. By combining foreign investment, advanced technology, and government support, GNA II is expected to play a key role in strengthening Brazil’s energy security while advancing sustainable development.
President Lula’s Vision for Brazil as a Clean Energy Leader
At the inauguration, President Luiz Inácio Lula da Silva emphasized Brazil’s potential to lead the global clean energy transition:
“With regard to the energy transition, Brazil has the capacity to become a dominant force,” he said.
Minister of Mines and Energy Alexandre Silveira highlighted that the project was made possible through close cooperation between the government and foreign investors, reinforcing Brazil’s attractiveness as a destination for sustainable energy projects.
