Some districts have been without electricity for 10 days or more, sparking protests by residents.
Some protesters have blockaded roads creating gridlock as many tried to leave Buenos Aires to celebrate New Year's Day somewhere cooler.
Military doctors have been setting up mobile stations to monitor the health of those most at risk from the heat.
Police and firefighters have been drafted in to help distribute water to those in need.
