The Brazilian government has awarded global energy solutions provider, Siemens, a contract for the turnkey construction of a new combined cycle power plant in the state of Rio de Janeiro.

The project is the integrated LNG-to-power development GNA 1 of Gás Natural Açu in the Port of Açu.

Siemens is providing an equity investment and owns one-third of the project company Gás Natural Açu (GNA) together with Brazil logistics company Prumo Logística S.A. and BP.

In addition, the company signed a long-term service agreement and will operate and maintain the plant to help ensure reliability, availability and operational performance.

With a capacity of approximately 1.3GW, the power plant will provide affordable and clean energy for Brazil.

Construction of the project already started in 2018 and is slated for operation at the beginning of 2021.

“Our participation in GNA demonstrates Siemens commitment to new commercial strategies that address the evolving challenges of an increasingly demanding energy market,” said Lisa Davis, CEO Siemens gas and power.

Davis added: “By integrating our offer along the energy value chain, the GNA 1 project clearly validates our comprehensive LNG-to-Power approach, which increases value to our partners and better meets the needs of the societies in which we operate.

“We look forward to continuing our innovative market approach with our global partners and supporting guaranteed electricity tariffs for our customers. I’m confident we will see more of this type of business model in the future.”

LNG-to-power project

GNA1 is the first fully integrated LNG-to-power project of this scope for the company, including the construction of a 1.3GW power plant as well as an LNG import and regasification terminal, a substation and a transmission line to connect the plant to the grid.

Siemens developed the project together with its partners BP and Prumo and is building the combined power plant turnkey in consortium with the Brazilian construction company Andrade Gutierrez.

For the project, Siemens is responsible for the delivery of the complete power island with three H-class gas turbines, one steam turbine, four generators and heat recovery steam generators and instrumentation and control systems.

The company will also provide long-term service and operation and maintenance for the power plant.

The service scope includes advanced remote monitoring and diagnostics, part of the company’s Digital Services portfolio.

GNA 1 LNG-fired combined cycle power plant

According to the company, the GNA 1 Liquefied Natural Gas (LNG)-fired combined cycle power plant will be one of the most efficient thermal power plants in Latin America.

It is the first phase of the Açu Gas Hub, a project under development in the Port of Açu Complex to provide a logistics solution for the reception, processing, consumption and transportation of natural gas from Campos and Santos Basins, as well as import and storage of LNG.

In December 2017 the project’s subsidiary, GNA 2, was selected as the winner in a Brazilian Electricity Auction and in summer 2018 Brazil’s Ministry of Mines and Energy authorised implementation of a second thermal power plant in the port of Açu.

With a total capacity of 3GW, Açu is expected to be the largest thermal power complex in Latin America.

A second phase will comprise additional thermal power projects under the environmental license for 6.4GW owned by GNA.
