GNA’s purpose is to generate reliable energy for the country, contributing to the
energy transition. With 3 GW of installed capacity, our natural gas-fired power
complex is the largest and most efficient in Latin America, representing an
investment of approximately R$12 billion.
Located at the Port of Açu, in the state of Rio de Janeiro, the project consists of
two combined-cycle natural gas power plants: UTE GNA I, in operation since 2021, and
UTE GNA II, which began commercial operations in May 2025. Both plants are connected
by an LNG terminal with a regasification capacity of up to 21 million cubic meters
per day.
Together, the two thermal power plants generate enough electricity to supply 14
million households — equivalent to the residential consumption of the states of Rio
de Janeiro, Minas Gerais, and Espírito Santo.
