  Recently, Comisso and Asenjo proposed a novel mechanism for harnessing energy
from black holes through magnetic reconnection. Our study focuses on exploring
the utilization of this mechanism on Konoplya-Rezzolla-Zhidenko (KRZ)
parametrized black holes to assess the impact of deformation parameters on
energy extraction. Among the various parameters, $\{\delta_1, \delta_2\}$ are
identified as the most important factors affecting the physics under
consideration. The influence of these two parameters on the ergoregion,
circular geodesics in the equatorial plane, and energy extraction from the KRZ
black holes through magnetic reconnection is carefully analyzed. Results
indicate that deviations from the Kerr metric have a notable influence on the
energy extraction process. Particularly, energy extraction is enhanced with
more negative ${\delta_1}$ or more positive ${\delta_2}$ within the range
constrained by current astronomical observations, resulting in significantly
higher maximum power and efficiency compared to the Kerr model. Moreover, when
${\delta_2}$ is sufficiently negative, extracting energy through this mechanism
becomes increasingly challenging, necessitating an exceptionally high black
hole spin.
