G\u00e1s Natural A\u00e7u (GNA), a joint venture between Siemens Energy Sip Brasil and bp, has launched operations at its second power plant in Porto do A\u00e7u, in northern Rio de Janeiro state. The project, which received R$7 billion in investments, is now the largest thermal power plant in operation in Brazil.<\/p>\n<\/div>\n

\n
\n

The new facility, GNA II, has an installed capacity of 1,673 megawatts and was recently approved for operation by Brazil\u2019s electricity regulator, ANEEL. Capable of supplying energy to roughly 8 million homes, the plant positions GNA as the operator of the largest natural gas-fired power complex in Latin America.<\/p>\n<\/div>\n

\n

GNA II complements the company\u2019s first plant, GNA I, which has been running since 2021 with a capacity of 1,338 MW. Together, the two units represent 17% of Brazil\u2019s thermal generation capacity and play a crucial role during dry seasons when hydroelectric output declines.<\/p>\n<\/div>\n

\n

The goal was to establish a gas hub at Porto do A\u00e7u, GNA CEO Emmanuel Delfosse told Valor. \u201cThese plants are like insurance for the power system as they come online when they\u2019re most needed.\u201d<\/p>\n<\/div>\n

\n

The plants are connected to a private liquefied natural gas (LNG) regasification terminal with a daily capacity of 21 million cubic meters. This allows GNA to import LNG and convert it back to gas for power generation. Combined, the thermal units consume about 12 million cubic meters per day, roughly equivalent to the energy consumption of the entire state of S\u00e3o Paulo, according to Mr. Delfosse.<\/p>\n<\/div>\n

\n

With GNA II operating under a 40% inflexibility clause, the system is contractually required to use the plant at least 40% of the time during Brazil\u2019s dry season, from July to November.<\/p>\n<\/div>\n

\n

The facility runs on natural gas and was contracted through Brazil\u2019s energy auctions. It operates in a combined-cycle configuration, improving efficiency and lowering emissions. However, it lacks \u201cfast ramp\u201d capability, meaning it must be brought online several days in advance\u2014a limitation in terms of operational flexibility.<\/p>\n<\/div>\n

\n

GNA II is part of the federal government\u2019s revamped Growth Acceleration Program (PAC), which targets key infrastructure investments. The total investment in the GNA power complex stands at R$12 billion. \u201cIt was a major technical and logistical challenge, especially during the pandemic,\u201d Mr. Delfosse said. \u201cDoing business in Brazil is complex. The scale of this industrial venture alone\u2014R$12 billion\u2014is remarkable.\u201d<\/p>\n<\/div>\n

\n

The project also has room for significant expansion, with 3.4 GW of additional capacity already authorized from an environmental standpoint. Any future development, however, will depend on demand in upcoming energy auctions.<\/p>\n<\/div>\n

\n
\n

GNA\u2019s shareholders played critical roles beyond capital contributions. Siemens Energy supplied three gas turbines and one steam turbine, while bp handled the gas supply. Chinese state-owned company SPIC joined the venture during a period of heavy Chinese investment in Brazil\u2019s power industry. Prumo Log\u00edstica, which manages Porto do A\u00e7u\u2019s infrastructure, is also a stakeholder in GNA I.<\/p>\n<\/div>\n
