million kilometres is the length of the German national grid. You could circumnavigate the globe at the Equator 45 times using the cables. The vast majority of the grid, namely a total of 1.44 million kilometres or 80 percent, is underground. Around 350,000 kilometres are power lines. The supra-regional high-voltage lines are 34,810 kilometres long. About 2,650 kilometres of new power lines are being planned as part of the Energy Reform.
