The U.S. Department of Energy's (DOE) Modern Grid Team has detailed seven key characteristics of the Smart Grid. $ ^$ {2 m9 w2 |: @$ d. G( h! z3 w/ t. K8 L$ l. O

' ~- j: [9 A! r9 ^The DOE has explicitly called out superconductors as one of the fundamental technologies needed for the Smart Grid. Superconductor cables can significantly enhance the flow of power on the transmission system, relieving grid congestion and increasing efficiency. Applied under our city streets, they can enable, for instance, widespread adoption of plug-in hybrid electric vehicles. These same cables also can automatically suppress power surges and enable resilient power grids that can survive attacks and disasters.
