29:20 Then David instructed the entire assembly: “Bless the Lord our God.” And the entire assembly blessed the Lord, the God of their fathers.

It is quite explicit in NERC’s tariffs, published in June 2012, that both the energy charge and the accompanying fixed monthly service charge, for the various categories of customers, are slightly increased annually. Under Nigeria’s tariff system, electricity prices are reviewed every five years, in order to make for adjustments and ensure cost recovery for the investors. I am quite watchful of not competing with a broken record (not being repetitive) over pointing out some grounds for rates increases (even if marginal) being fallout of the power sector privatisation, since I have already reasoned along this line.
