Members of organised labour are currently occupying Nigerian Electricity Regulatory Commission (NERC) offices nationwide.
The rise in energy rates for users in the Band A category is being opposed by the Nigeria Labour Congress (NLC), Trade Union Congress (TUC), and other affiliated organisations.
The power rate for users in the classification was approved by NERC on April 3 and is now N225 per kwh instead of N66.
The demand from organised labour is for the increase to be reversed and for talks to resume.
The unionists, on Monday, arrived at the NERC office located at Novel House in Ikeja, Lagos, around 9:40am.
Addressing workers at the complex, Funmi Sessi, NLC Lagos chairperson, asked them to vacate their offices.
Sessi said the unions do not understand the regulatory functions of NERC amid the epileptic power supply in the country.
In Abuja, the unions besieged the NERC office located in the Central Business District.
Labour has also shut NERC offices in Jos, Akwa Ibom, Benin, Kaduna and in other capital cities across the country.
