Calculating the Power of Not-Lightning

[Nullflowerblush]

The Seventh Tier Magic Mjölnir is a magical technique that sends a beam of sorts into the sky, causing dark clouds to close in, before exciting and discharging a large beam of, what appears to be, energy with streaks of electricity surrounding it. The Demon Queen's replicated variant does the same thing.

Is there anyway to calculate its power?

Things to note:

1. Despite never causing an on-screen explosion, the beams are incredibly large.
2. There is some electrical discharge from the beam.
3. The Demon Queen simply charging up the attack caused the ground around her to tremor.

Wait, would this qualify for real lightning, or at least 8-C?

Also also, there is a weaker technique that does the same thing and is called "Thunderclap Rampage", if that means anything.

Do the beams themselves act like real electricity?
