The energy of the blackhole would not be necessarily electromagnetic waves or e/m fields in static form, there are views where gravitation field has energy density, allowing a bh can be made of pure gravity! As gravitational field can "escape" from event horizon, the energy of the bh might be comfortably stored as finite gravity energy density without requiring singularity.
