The sentence about Wikipedia suggests that by "electricity", you mean the electrical charge.
However, GeV isn't a unit of the electric charge. It's a unit of energy; the usual macroscopic unit of the same quantity – energy – is 1 joule. It is something completely different than the electrical charge whose unit is 1 coulomb.
The neutrinos have charge $Q=0$ but energy $E\sim O(10)~$GeV. The rest mass is, by the way, also nonzero but much smaller than the equivalent of the energy, about $m_0\sim O(1)~$meV/$c^2$.
By the way, from the terminological viewpoint, the original title of this question "units of neutrino" is nonsensical. There may be units of physical quantities by neutrinos are not physical quantities.
