How heavy is electricity?

Electricity is just a flow of electrons, and these electrons do have mass, but it is an absurdly small amount.

Electricity is, strictly speaking, just the flow of electrons and so it doesn’t make sense to talk of it weighing anything as it’s an abstract quantity. That said, the electrons themselves certainly have mass, albeit very little: each one is around 2000 times lighter than a proton, which itself weighs just a billion-billion-billionth of a kilogram.
