With investments of more than BRL 6 billion, the Porto do Açu plants will be the most efficient thermoelectric plants in Latin America, capable of supplying energy to 14 million homes

Siemens Energy has just won a contract for the construction of the GNA II Thermoelectric Plant, located in Porto do Açu, in the state of Rio de Janeiro – the largest LNG complex in Latin America. UTE GNA II will be the second combined cycle power plant that Siemens Energy will build under a turnkey in the thermoelectric pole and will have an installed capacity of 1,7 gigawatt (GW).

According to Siemens, construction of the plant, which is already underway, takes place after the successful commissioning of GNA I, in the second half of 2021.

The GNA I and GNA II plants will be the most efficient thermoelectric plants in Latin America

With a combined capacity of 3 GW, GNA I and GNA II will be able to supply electricity for the equivalent consumption of 14 million homes. This second order will feature the first application in Brazil of the HL class gas turbine.

The combined cycle plants powered by liquefied natural gas (LNG) will be the most efficient thermoelectric plants in Latin America. The total value of the project is approximately €1 billion.

Siemens Energy's scope foresees the delivery of the entire energy island, which consists of three high-efficiency HL class gas turbines, one steam turbine, four electric generators and three heat recovery steam generators (HRSG), in addition to of instrumentation and control systems.

In addition, the services offered by Siemens Energy will also cover the long-term operation and maintenance (O&M) of the plant, including advanced remote monitoring and diagnosis by the Remote Operation Center, located in Jundiaí, São Paulo.

Siemens has Andrade Gutierrez as a partner, which will supply the civil works, infrastructure and assembly of UTE GNA II

The plant is being built jointly with the consortium partner Andrade Gutierrez, which will provide civil works, infrastructure and assembly.

“Our participation in this exceptional project reinforces how our comprehensive LNG – for – Energy approach; increases added value for our partners and also meets the need for affordable and reliable energy,” says Jochen Eickholt, Member of the Executive Board of Siemens Energy AG.

“This project is strategic, not only for its grandeur, but also for its geographic location, close to the two main gas pipeline systems in Brazil, in the Northeast and Southeast regions of the country. It is important to point out that our gas turbines for GNA II are ready to burn hydrogen afterwards. This means that our technology is future-proof for our customers,” adds Eickholt.

The two plants will supply energy to regions such as Espírito Santo, Minas Gerais and Rio de Janeiro

The Gas Natural do Açu project includes the construction of two thermoelectric plants, an LNG regasification terminal, based on a FSRU (Floating Storage Regasification Unit), in addition to substations and transmission lines to interconnect the plants to the National Interconnected System.

The thermoelectric complex is part of the Polo Gás do Açu, a project under development at the Açu Port Complex that aims to provide a logistical solution for receiving, processing, converting into electricity and transporting natural gas in the Campos and Santos basins, as well as for import and store LNG. A second phase will comprise additional thermal power projects under the 6,4 GW environmental license owned by GNA.

The construction of the GNA I plant started in January 2018 and entered into commercial operation in September 2021. The two plants will supply energy to regions such as Espírito Santo, Minas Gerais and Rio de Janeiro within the National Interconnected System.
