Lebanon is without electricity since Saturday as the two major power plants shut down because of a severe fuel shortage.
The state news agency and other media outlets reported that power supply is not likely to resume for several days.
Lebanon's economy has been in a dire state.
The financially strapped country virtually defaulted in March 2020.
The coronavirus pandemic and massive port explosion in its capital, Beirut, in August of last year hurt the economy further.
A lack of foreign currency hindered imports of gasoline and heavy oil, which led to a chronic power supply shortage.
Even in the central part of Beirut, residents have had only a few hours of electricity a day since the beginning of the year.
The current government, which was formed in September after more than a year of political vacuum, now has the difficult task of rebuilding the economy.
