I travelled to leepa valley last week end on bike.. We had to take an NOC from DC of balla hatian. After than we were allowed to enter into Leepa Valley. There are many check posts and they make your entry in the register.
If you want to be on local transport than from muzafrabad.. than you have to take buss.. it will take you to reshian.. And will charge 170 Rs.. Than you have 2 options either hire the jeep they will charge from 2000-2500 Rs upto leepa valley. Or for a single person they take 250 Rs...
If you go there from jeep ask them to take you from mojian .. that side has many places to see.
There is no electricity problem in Leepa... I stayed at chinar hotel rest house...In Leepa there is a place name bara hazari.. Its a mountain top 12000 ft altitude. Nice place to visit.. But its route will be open after 15th-20th June. There is also place name tareet shareef, few tombs of Peer are there, from there you can see LOC and indian checkposts as well.
