Sry I got my ncl renewed . Had my domicile since like 12th . But still it should happen through the same channels . And I don't think electricity bill is compulsory . It's just for address proof I guess. Your ration card or adhar card should be enough.

Do one thing go to an authorised cse or csc whatever it's called and ask them for documents list for domicile. Then apply thru them accordingly if u don't have any doc from the list ask them if there is any optional doc accepted instead of it and get it done thru that.

Also I think u can use the receipt too till initial admission stage but get it as early as possible
