A unitary system is one level centralized government without any semi-autonomous component units. This means that there is no state or regional government under unitary system. In this backward unitary system Nigeria runs presently, state governments does not have any meaningful control on electricity, railway and other resources in their various states. The governance failure will continue until Nigeria is restructured into a fiscal federal system. Fiscal federation is an unavoidable destination for Nigeria, the earlier the better.
