I am currently playing the FTB Revelation modpack (LP 0.10.3.62 mod is manually added) in MC 1.12.2 and I can't craft the logistics power providers, Power supplier upgrades and the power transportation upgrades. I could not find any crafting recipes online either and I am not sure if any other mod has disabled them. In creative mode I was able to test everything and the power transportation seemed to work except for the MJ power provider (it didnt connect with any other pipe).

They don't have recipes because we have not looked at them in MC 1.12 yet. It is good to know that they worked for you. That is input that will go into our decision when to work on them and finally provide them with a recipe again.
