Features

Long Distance Transmission with Lower Cost
  • HVDC is the only solution for an overhead transmission longer than 300km or submarine/underground 40km thanks to the DC characteristics.
Eco-friendly Transmission
  • HVDC system has lower environmental impact because it requires fewer overhead lines compared to the AC system. The technology is also the key component in the future energy system based on renewable energy sources.
Optimal Grid Management
  • HVDC can directly interconnect load centers with huge energy sources efficiently. Therefore, negative impact on the grid is minimized. HVDC also improves the performance of the AC grid by means of additional controllability.
