Germany-based energy company Siemens Energy has secured a €1bn ($1.1bn) turnkey construction contract from Gás Natural Açu (GNA) to build a 1.7GW combined cycle power plant, UTE GNA II, in Brazil.

The plant will be built as part of GNA II, an integrated liquefied natural gas (LNG) to power project, at Port of Açu in Rio de Janeiro.

The contract comes after Siemens Energy successfully commissioned the GNA I combined-cycle power plant earlier this year.

Siemens Energy will deliver an entire power island for GNA II, including three HL-class gas turbines, four electric generators, one steam turbine and three heat recovery steam generators (HRSG), as well as instrumentation and control systems.

The company will build the power plant in cooperation with its consortium partner Andrade Gutierrez, which will be responsible for civil, infrastructure and construction works.

The project will involve building two thermal power plants and an LNG regasification terminal based on a floating storage regasification unit (FSRU), as well as substations and transmission lines linking the plants to the national interconnected system.

Siemens Energy has also agreed to provide long-term operation and maintenance to the power plant.

GNA I and II will have a combined capacity of 3GW and be able to meet the power requirements of 14 million households.

Electricity from the two power plants will be supplied to regions within the national interconnected system, including Espírito Santo, Minas Gerais and Rio de Janeiro.

Siemens Energy executive board member Jochen Eickholt said: “Our participation in this outstanding project reinforces how our comprehensive LNG-to-power approach increases the value to our partners, and also meets the need for affordable and reliable energy.

“This project is strategic, not only for its grandeur, but also for its geographical location, close to the two main gas pipelines systems in Brazil, in the north-east and south-east of the country.”
