Hey there. The electricity charges are included in the Hostel charges . There is no additional payment to be made for electricity
Mess charges are variable. It costs nearly 113 rupees per day for 4 snacks. You can opt for max 7 graces in a month( That means you do not eat complete day in mess and hence you do not need to pay 113 rupees per day) , that too has a procedure to be followed. Nothing complicated. Many people apply for grace.
