Abstract The present paper focuses on FACTS (Flexible Alternating Current Transmission System) and HVDC (High Voltage Direct Current) transmission technologies. Particular attention is paid to different specific technical, economic and environmental features of these power electronics-based devices. Final aim of the paper is the investigation of the role that FACTS and HVDC may play towards the development of the future pan-European transmission system. 1 Introduction In the European Union (EU), issues concerning security of energy supply, electricity market restructuring and increasing environmental constraints represent key drivers for new trends which may have significant impact on the design and the operation of the electric power system. This is particularly true for the European electricity grids, which are on the critical path to meet the EU’s climate change and energy policy objectives for 2020 and beyond. Concerning the European transmission network, the challenge will be the integration of very large amounts of variable renewable energy sources (RES), especially wind and also solar, into the power system, while keeping its reliability levels, in a liberalised background. To this scope, a more flexible transmission grid would be then needed. Furthermore, the ongoing energy market liberalisation process in Europe is leading to t
