Acute electricity crisis characterised by epileptic and inadequate supply remains a major hindrance to achieving sustainable development in Nigeria. The problems of poor electricity generation, transmission, and distribution have led to a slowdown of industrialisation. The effect of this is evident in the poor standard of living for the majority of the population and the poor state of the economy. While there have been concerted efforts at improving the power sector, pumped-hydro storage consideration and applicability as a potential solution has received scant attention in Nigeria. Meanwhile, its application in electricity networks merits reflection considering the present state of Nigeria electricity. This study seeks to propose the application of P-HS in Nigeria and the steps needed to support its adoption. The attempt thus raised a number of questions. Such as, what are the possible factors that are slowing the application of P-HS? What are the needed steps to accelerate the P-HS application in Nigeria? What are the specific ways in which P-HS can be applied to solve the country’s electricity problem? Thereafter, a conceptual framework to describe our thought was presented and the implications of adopting P-HS in Nigeria were discussed. These include energy storage, generation and ancillary services.
