Despite current drop in power generation and supply, the directive by the Senate to suspend the new 45 per cent tariff hike remains invalid, as the Nigerian Electricity Regulatory Commission, NERC, said it lacked the constitutional authority to reverse the order. This came as the leadership of organised labour called for the probe of the NERC, and former chairman of the commission, Dr. Dr Sam Amadi, CEO, NERC , over the controversy surrounding the recent hike in electricity tariff. The declaration by NERC came as power generation in the country has plummeted to 3,664 megawatts, MW, according to information from the Federal Ministry of Power. This is happening at a time the distribution companies, DISCOs, are insisting on increasing tariff on all categories of customers without commensurate increase in electricity supply.
