The Lunar Base scheduled for construction in 2050 apparently will be underground; a reasonable choice for survival and safety, yet high temperature super-conducting wire may be established on the surface for several uses including transportation power and bringing electricity to underground caves, etc.
High temperature super-conducting ceramics have been a N.A.S.A. priority for some time. With the cold nights of the lunar surface superconducting wires for a power grid can be practical and cost efficient to install. Automated robot dogs can unspool power lines manufactured on earth and launched to the moon base and stretch them out along selected routes that electric surface vehicles can travel.
It would of course be possible to use very small rockets or mortars to launch wire ends outward from a spool and make a radius of super-conducting power lines.
