We obtain the energy distribution in the dyadosphere region for a Reissner-Nordström black hole. We find that the energy-momentum prescriptions of Einstein, Landau-Lifshitz, Papapetrou, and Weinberg give the same and acceptable energy distribution.10 pages, no figuresGeneral Relativity and Quantum Cosmologytext
