In operation since 2021, UTE GNA I is the largest natural gas power plant in
Southeastern Brazil. Located at the Port of Açu, in the state of Rio de Janeiro, it
has an installed capacity of 1.3 GW — equivalent to the consumption of 6 million
households.
UTE GNA I is part of the largest natural gas-fired thermal power complex in Latin
America, with 3 GW of installed capacity. The complex includes two power plants —
UTE GNA I and UTE GNA II — connected by a privately operated LNG Terminal.
Advanced Technology and Energy Efficiency
UTE GNA I is a combined-cycle power plant consisting of 3 gas turbines and 1 steam
turbine. Thanks to cutting-edge technology investments, approximately 30% of the
energy is generated without additional gas consumption, through the steam turbine —
contributing significantly to higher energy efficiency.
