Siemens Energy has signed four contracts with Eletrobras worth over approximately $60 million USD (R$300 million) to update and renew transmission assets in various regions of Brazil. These contracts focus on improving depreciated assets and enhancing grid resilience, a necessity as the country's energy mix increasingly incorporates renewable sources like wind and solar.

A key project under this agreement is in the Madeira River area, where Siemens Energy will install an online monitoring system for gases dissolved in insulating oil for transformer stations. This technology helps detect potential transformer failures before they occur, ensuring a stable and reliable power supply in a critical region.

André Clark, vice president of Siemens Energy for Latin America, explained that Brazil’s transmission system is reliable but aging. With climate change and extreme weather events becoming more frequent, updates are needed to ensure continued performance and grid stability.

Robson Campos, Eletrobras’s vice president of engineering, confirmed that these upgrades are part of a larger R$3.3 billion investment planned for 2024, with deliveries of the equipment expected between 2024 and 2026.

The updates will also include the Grajaú substation in Rio de Janeiro, supplying nearly 40% of the city’s electricity, and the installation of new fixed series capacitor (FSC) banks for the Imperatriz line in Maranhão to boost transmission capacity.
