There are fears that residents of Rivers, Bayelsa, Akwa Ibom and Cross River States may be without electricity in the next five days.
This follows the shutting down of major transmission and distribution centres of Port Harcourt electricity distribution company, in the four states by National Union of Electricity Employees.
This is over allegations of poor welfare and refusal of the company to allow the workers to unionize.
Our correspondent Monica Ogwa reports that the picketing also coincided with a peaceful protest by electricity consumers from Rumuola area of Port Harcourt over what they termed injustice, poor power supply and inaccurate billing system.
In another development, Akwa Ibom State Governor Udom Emmanuel has appealed to the indigeneous people of Ikot Ada Akpan, Oku Iboku clan in Itu Local Government Area of the state to remain law abiding, and give necessary information to security personnel to ensure adequate security in the community.
He made the plea when he visited the community following reports of renewed attacks on the people by their neighbours alleged to have come from Ikot Offiong Community in Cross River State.
According to the governor, efforts are on to uncover the root cause of the hostility.
