Kira doesn't have "electrical powers" in the way you describe.

She can absorb electricity but, in both instances shown on screen, this appears to be a reflex action and not something she actually controls.

She has produced electricity in large quantities only twice.

In the first instance she was being guided by her mother to repair the sword.

In the second instance she was completely out of control and interacting involuntarily with the Eichen House electromagnetic field.

There is no indication that Kira has more than a rudimentary understanding of her electrical abilities at this point.
