At Aath Chowk, JI Karachi chief Monem Zafar also sought a forensic audit of K-Electric and answers on the Rs25.28 billion Lyari Transformation Project.
Jamaat-e-Islami on Sunday called for an immediate end to prolonged and unannounced load-shedding in Lyari.
JI Karachi chief Monem Zafar said some areas get power for only four to six hours a day, with outages of 18 to 20 hours.
The party demanded a forensic audit of K-Electric and cited a Rs164 billion subsidy this year and Rs1,500 billion since privatisation.
Zafar asked the Sindh government where Rs25.28 billion announced for the Lyari Transformation Project was spent.
He objected to cutting supply for whole neighbourhoods over theft or unpaid bills by some residents.
