“Our transmission systems have been helping secure energy supplies in Brazil for decades,” said Niklas Persson, CEO of Hitachi Energy’s grid integration business. “We are proud to support Taesa with state-of-the-art HVDC control systems and Hitachi Energy Service solutions, making the connection safer. Based on almost 70 years of experience, our services will extend the life of the system, improve its availability and reliability. “
“Our mission is to connect Brazil to safe and reliable electricity, creating value for society and transmitting energy with excellence and quality,” said Emmanuel Pasqua de Moraes, Head of Development Planning and Engineering at Taesa. “Cross-border connections like Garabi are central to this mission, and this Hitachi Energy HVDC system is an important part of Brazil’s national interconnection system’s energy security, and international connections increase the energy security of our system.”
HVDC systems are usually used for large-scale electricity transmission and exchange over long distances between two HVDC converter stations, but the Garabi HVDC converter station is a single-site system.1 Back-to-back stations use sophisticated digital control of the HVDC system to precisely control the flow and characteristics of the electricity supply, which offers many benefits for network management and stability.
