  We consider the Penrose process near the naked singularity in the
Reissner-Nordstr\"{o}m metric. Particle 0 falls from infinity and decays to two
fragments at some point $r_{0}$. We show that the energy extraction due to this
process can be indefinitely large in the limit $r_{0}\rightarrow 0$. In doing
so, the value of the particle charge can remain bounded, in contrast to the
previously known examples of the Penrose process in the electric field with
unbounded energy extraction. The effect persists even in the limit of the flat
pace-time.
