Neat, thanks ! Browsing other Wikipedia articles let me know that one of the longest existing HVDC is the Rio Madeira HVDC system[1] at 2375 km, and the longest underwater HDVC is the North Sea Link [2] at 720 km So while the Singaporian-Australian link still feel monumental it's not as science-fictiony as I initially thought.
