About two million households in Nigeria are set to bear the burden of an inefficient power sector as the Nigerian Electricity Regulatory Commission (NERC) on Wednesday increased the electricity tariff of 'Band A' customers from N70 to N225 for every kilowatt per hour (kWh). This comes amid indications that the price of prepaid meters may skyrocket to above N300,000 as manufacturers and the NERC push for a liberalised market.
