Power firms are pushing for a fresh 100 percent increase in electricity tariff, the second in six months.
The electricity distribution companies (DisCos) raised tariff by over 45 percent in February.
The DisCos had written to the regulatory authority, the Nigerian Electricity Regulatory Commission (NERC) demanding hike in tariff from the current average of N24 per kilowatt (for residential consumers) to N50 per kilowatt.
However, the Director General of the Manufacturers Association of Nigeria (MAN), Mr Remi Ogunmefun said that his association had opposed that move in writing to the NERC.
The NERC announced the 45 percent hike in electricity tariff with effect from February 1, 2016, and said the increase would enhance service delivery and customer satisfaction.
