I have found a website concerning ideas for powers based by lightning, which is electricity.

This website shows three out of four categories: Electricity Manipulation, Energy Attacks, and Technology Manipulation (the fourth one is Weather Manipulation, which I am not sure you would allow a transplant to influence it).

Hopefully, it would help. :)
