In particular, China, although lacking a proper (interconnected) HVDC grid, has built in the last two decades more than 30 HVDC lines. Other countries and continents worldwide have lately emerged as growing markets for HVDC technology.
All the HVDC projects in Europe (with one exception) are point-to-point with specific parameters meeting the local conditions (grid connection, voltage levels, capacity). All the HVDC projects deployed in Europe are “unique”, that is all the equipment is sized to that specific project no two projects are alike.
The same companies built or extensively contributed to projects worldwide. All the major companies in the field that innovated and set the standards are located in Europe. High Voltage Direct Current (HVDC) technologies, due to their lower losses and smaller environmental impact, promise to be the cornerstones of such global power grid.Įurope has been at the forefront of HVDC research, development and deployment since the beginning of large-scale pilot projects in 1950s-1960s. A more flexible, yet robust, transmission grid may be instrumental to interlink distant electricity markets and take advantage of the low-carbon resources temporal and spatial complementarity.Īll the above may drive the realisation of a transcontinental higher transfer capacity system to transport large amounts of electricity over long distances. To fully utilise these resources, the power grid must be enhanced to allow electricity to be transported to the main demand and storage centres. The energy production from renewable sources also greatly depends on local weather conditions. offshore sea) or where grid transfer capacity is low.
Sizable renewable energy potential is concentrated in sites far from the power grid (e.g. The best locations for the generation of renewable electricity are not uniformly distributed across the European continent and worldwide. Diverse geopolitical, market integration and techno-economic dynamics push for further interconnecting the higher voltage systems across countries and continents.
