Electrostatic potential independent of distance?

Say I have a packet of electrons just sitting there, before they repel each other, what is their potential energy?

I have no idea of how to calculate their potential energy since at r = 0 , U = infinity, which is not helpful since my problem requires U to be finite but the only way I know of that being true is that r does not = 0.

Any way of calculating PE without distance?

hmmmm , I dont think this is possible .. do you have the exact question ?

I think it is impossible and so I just forced some boundary conditions. i.e. initial separation is not = 0.
