Siemens Energy to construct 1.7 GW combined cycle power plant in Brazil

Siemens Energy has secured an order for the turnkey construction of the combined cycle power plant UTE GNA II in the integrated LNG-to-Power project GNA II, located at Port of Açu, in the Brazilian state of Rio de Janeiro.

Following the commissioning of GNA I in summer 2021, GNA II will be the second turnkey combined cycle power plant that Siemens Energy will build in the thermoelectric hub and will add further capacity of 1.7 gigawatts (GW). With a combined capacity of 3 GW, the two power plants will be able to provide enough electricity for the consumption of around 14 million households.

The combined cycle plants powered by liquefied natural gas (LNG) will be the most efficient thermal power plants in Latin America. The total project amount is approximately EUR1 billion (US$1.13 billion).

The scope for Siemens Energy foresees the entire power island delivery, which consists of three highly efficient HL class gas turbines, one steam turbine, four electric generators, and three heat recovery steam generators (HRSG), in addition to instrumentation and control systems. Siemens Energy is also responsible for long-term operation and maintenance (O&M) of the plant, including advanced remote monitoring and diagnostics by the Remote Operation Center, located in Jundiaí, São Paulo.

The power plant is being built together with the consortium partner Andrade Gutierrez who will provide the civil works, the infrastructure and the erection works.
