HVDC Hokkaido–Honshu

The HVDC Hokkaidō–Honshū or Hokkaidō–Honshū HVDC Link (北海道・本州間電力連系設備, Hokkaidō-Honshū-kan Denryoku Renkei Setsubi), Kitahon HVDC Link (北本連系, Kitahon Renkei) for short, is a 193 kilometres (120 mi) long high voltage direct current transmission line for the interconnection of the power grids of Hokkaidō (Hakodate static inverter station in Nanae) and Honshū (Kamikita static inverter station in Tohoku, Aomori Prefecture), Japan. The project went into service in 1979 by the Electric Power Development Company (J-POWER). A 149 kilometres (93 mi) long overhead line and a 44 kilometres (27 mi) long submarine cable connects the terminals. The HVDC Hokkaidō–Honshū is a monopolar HVDC line with an operating voltage of 250 kV and rated power of 300 megawatts. This HVDC system uses thyristor static inverters.

gollark: Anyway, for, let us be honestly honest, something which is probably not a high-traffic website, you don't need a full server which will just idle constantly.
gollark: Technically, it already exists.
gollark: Yes, we emulate Raspberry Pis at about 0.03% of normal speed by using a Raspberry Pi to simulate a Raspberry Pi CPU, with the memory and disk on Google Drive.
gollark: More domains Coming Soon™.
gollark: Oh, and we have free osmarks.net subdomains, of course.
