The Brazilian government's energy research company, EPE, has unveiled forecasts indicating a substantial investment demand in power transmission in Brazil. The projected capex ranges from 114.7bn to 153bn reais by 2034, with investments allocated for transmission lines and substations. This surge in investment is attributed to the expected growth in datacenters and green hydrogen projects within the country. EPE's recommendations include reinforcing systems in specific regions, introducing new technologies like FACT and SSSC for grid optimization, and focusing on reducing service charges in Amazonas. Moreover, studies are underway to ensure the resilience of the electricity system in regions prone to extreme weather events, such as Acre and Rondônia. Additionally, measures are being planned to address the ageing infrastructure of Brazil's transmission system through strategic investments. The shift towards renewable energy sources like wind and solar plants is also influencing the country's power generation capacity, mainly concentrated in the northeast region. The article highlights key projects and initiatives aimed at enhancing the efficiency and reliability of Brazil's power transmission network. These efforts align with the country's ambitions to strengthen its energy infrastructure and accommodate the growing demand for power, particularly in sectors like datacenters and green hydrogen production.
