Don't be confused by the watts-to-watts comparison.

Drone fleet operators would be paying more for ubiquitous access to drone parking on (presumably inspected and pre-approved segments of) powerlines. The energy supply is almost an ancillary service, but an important one.

Just like with EV charging today, the energy cost will presumably be higher than your household bill, or similar billing schemes. "The house always wins."
