If you want to put in the island, and don't see the need for electrical, there is a way around the code requirement.

There is not a code requirement for a piece of furniture! If you don't attach the unit to the floor, then it is furniture, and code requirements do not play a role.

Honestly, if you are putting in the island, it is probably best to bite the bullet, and get electrical there. Just wanted to make you aware of how to sidestep the code requirement.
