GrandPower is a library made by Technici4n with the goal to unify long energy capabilities for NeoForge, it's goal is to be as easy to implement as possible for modders
It is currently only used by Modern industrialization but I have hopes that Draconic evolution's popularity could make that library more know to modders benefiting from such a library

Interesting, but that's kind of why Brandon's Core has the OP system split off from Draconic Evolution. I'll leave it up to @brandon3055.
