Gas Natural Acu

completed

  Prumo Logística S.A. (Prumo), BP Global Investments PLC (BP), and Siemens AG (Siemens) are the sponsors of the Gas Natural Açu (GNA) project, a greenfield gas-fired combined cycle thermal power plant located at the Porto do Açu, a brownfield port and industrial complex located in São João da Barra, on the northern coast of the state of Rio de Janeiro, Brazil.    The project consists of a 1,298 MW gas-fired combined-cycle power plant using three Siemens SFT6-8000 H gas turbines with corresponding Heat Recovery Steam Generators (HRSG) and one Siemens SST6-5000 steam turbine. The plant is designed to operate as a peaking facility, with a 30% expected utilization factor and a planned annual 3,472 GWh. It will be connected to the grid via a 52-km double circuit 345-kV transmission line between the Porto do Açu and the Campos dos Goytacazes substation and will provide electricity to the National Interconnected System (SIN, its Portuguese acronym).    The project includes a liquefied natural gas (LNG) marine import terminal to be built on the north pier of the Porto do Açu, with a fully dedicated chartered Floating Storage and Regasification Unit (FSRU) of up to 21 million m 3 /day capacity, ship-to-ship LNG transfer systems from LNG carriers to the FSRU to be offloaded by fixed unloading arms, and a 12-inch diameter high pressure natural gas pipeline to transfer the regasified LNG from the FSRU to the plant. Seawater cooling towers will be used for the condenser cooling. The water intake and cooling water discharge will be located offshore at opposite sides of the north pier.      The plant will be located approximately 1,600 m from the north pier and will be constructed on a 400,000 m 2  site in the Porto do Açu.  The project is potentially the first of four gas-fired power plants to be developed by GNA at the Porto do Açu, which has a preliminary license of 6,400 MW generating capacity.   The transmission line (T-Line) will have a 60-m wide right-of-way (ROW) and 123 towers that have already been built and installed.  The line will cross the municipalities of São João da Barra and Campos dos Goytacazes where the SIN connecting substation is located.   GNA will have a long-term fuel supply agreement with BP, and has also acquired a 23-year power purchase agreement from Bolognesi Group with 36 distribution companies in Brazil beginning in January 2021.  The project will enter into a charter agreement for the FSRU.  The project is anticipated to have a fully-wrapped, turn-key engineering, procurement, and construction (EPC) contract with a Siemens-Andrade Gutierrez consortium for the plant and T-Line. Operation and maintenance services will be provided by Siemens under a long-term service agreement.
