I once reinstalled electric to an island.
I had to get permission from landholder who had the nearest connection point.
I contacted the electric company that supplied my service and they
put me in touch with a Texas company which made submersible cable (required for safety, big price).
A local electrical contractor installed the connection and a barge lowered the heavy cable into the water.
The cable had to be an exact length since it could not be spliced.
