We consider Single Black Holes (SBHs) of 103 M as possible parent objects for cosmological GRBs. The latter are the result of the energy release of SBHs magnetosphere inhomogeneities. The percolation nature of this release yields a unique power law for the GRBs energy distribution that is E (with β = 1.7-1.8), i.e. the same observed in solar flares, flare stars and X-ray sources. The number of GRBs per year per galaxy is about 10-2-10-1 with total energy 1047-1050 ergs for beaming factor of about 10-4-10-5.
