Hitachi Energy to enhance Mediterranean electricity connectivity with HVDC technology
In a significant development for European energy infrastructure, Hitachi Energy has been selected by Terna, the Italian Transmission System Operator, and Électricité de France (EDF), the integrated French energy company, to implement its advanced high-voltage direct current (HVDC) technology. This project, named Sa.Co.I.3 (Sardinia – Corsica – Italy), aims to enhance the electrical connection between Italy’s mainland and the islands of Corsica and Sardinia, boosting the capacity to 400 megawatts (MW).
Technological Advancements and Strategic Importance
The Sa.Co.I.3 project is set to completely overhaul the existing transmission equipment, replacing it with state-of-the-art HVDC technology in a bipolar, multi-terminal scheme. This upgrade will significantly enhance the efficiency, reliability, and sustainability of the electricity system serving the large Mediterranean islands and Tuscany. As part of the EU’s list of Projects of Common Interest (PCI), Sa.Co.I.3 holds strategic importance for Europe’s energy security and integration.
Innovative Solutions for Efficient Power Transmission
Hitachi Energy will deploy its HVDC Light solution, which utilizes voltage source converter (VSC) technology. This system efficiently converts alternating current (AC) to direct current (DC) for long-distance, underwater transmission, and then back to AC as it integrates into the grid. Niklas Persson, Managing Director of Hitachi Energy’s Grid Integration business, expressed enthusiasm about the project: “We are excited to have been selected by EDF and Terna to develop the Sa.Co.I.3 project and help secure power for the people living on these islands.”
Collaboration for Optimal Implementation
The project also involves collaboration with Pellegrini and Razel-Bec, who will handle the civil and installation aspects. This partnership leverages the core competencies of all parties to deliver an industry-leading solution, positioning Hitachi Energy as a key player in supporting the global energy transition, particularly in Europe as it moves towards large DC grids.
The implementation of multi-terminal HVDC systems, like Sa.Co.I.3, is increasingly vital as they serve as key enablers for the energy transition. By connecting multiple points efficiently, these systems facilitate a more resilient and flexible energy network, essential for integrating renewable energy sources and enhancing grid stability across regions.
The Sa.Co.I.3 project not only underscores the technical capabilities of Hitachi Energy in pioneering HVDC technology but also reflects the growing emphasis on sustainable and interconnected energy solutions in Europe. As the continent progresses towards an integrated and low-carbon energy system, initiatives like Sa.Co.I.3 play a crucial role in shaping its energy future.
