Yes young Thor has called down lightning, but according to canon vis a vis Aaron's writing, all power of lightning & thunder comes from the Mother of Storms.
Even Odin had a hard time taming the Mother of Storms and when it was put into Mjolnir it would whisper to Thor, hence him wielding lighting. The Mother of Storms whispered to Jane too, that is why she knew that that there must always be a Thor.
Yes Thor's powers have been duplicated, and again that is because the Mother of Storms allowed it. Beta Ray Bill is a noble hero who is worthy, so why couldn't the Mother of Storms imbue that power to him?
