(J-POWER). A overhead line and a submarine cable connect 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
converters.
In 2019 a second HVDC system between the two islands, with a rated power of 300 MW and using Voltage-Source Converters, was put into operation.
