In the year 1987 on July the 23, the met' Tokyo experienced a devastating blackout caused by wild voltage instability. In the blackout more than 8 GW and 2.8 million homes affected. Lessons learned from the blackout have formed the foundation of voltage and reactive power control, currently adopted (TBO) TOYKO BLACKOUT. The very material used to harness the volatile voltage has been forged to create TBO spats.
Some artistic license has been applied.... I don't know the history of Tokyo... But these spats have been made from volatile voltage.
