Today, the longest superconducting energy cable in the world was integrated officially into the power grid of a German city. The cable of about 1 kilometer (0.62 miles) in length now connects two transformer stations in the city center of Essen. This marks the start of a landmark practical test for the future energy supply of inner cities by RWE, Nexans, and KIT. Compared to conventional cables, the highly efficient and space-saving superconducting cable technology transports five times more power with hardly any losses.
