Abadi had also ordered an internal government investigation into Electricity Minister Qassim al-Fahdawi's role in the deterioration of utility services. There was no immediate comment from Fahdawi, Washington Post reported.
Protests have swept cities in the long neglected south, Iraq's Shia Muslim heartland, over widespread electricity outages during the blistering hot Iraqi summer, a lack of jobs and proper government services, and pervasive graft.
On Saturday, Abadi sacked five local election officials after they were charged with acts of corruption during the May 12 parliamentary election.
Abadi's moves come after Iraq's top Shia cleric, Grand Ayatollah Ali al-Sistani, urged government action to fight corruption to defuse unrest.
Public anger is mounting at a time when politicians are struggling to form a new government after a May 12 election that was marred by allegations of fraud, prompting a recount.
