Lebanon’s power supplies are back to normal after an outage the previous day when the country’s two biggest power stations shut down because of a fuel shortage, the energy ministry says.

The closure piled further hardship on Lebanese struggling with job losses, soaring prices and hunger wrought by the country’s worsening financial meltdown.

The ministry said it had received central bank approval for $US100 million ($A137 million) in credit to issue fuel import tenders for electricity generation, adding the country’s grid had resumed supplying the same amount of electricity as before the complete outage.

On Saturday, Lebanon’s two largest power stations, Zahrani and Deir Ammar plants, shut down due to fuel shortages bringing the Lebanese power network to a complete halt.

The Lebanese army agreed on Sunday night (Australian time) to provide 6000 kilolitres of fuel for the two power stations, the state electricity company said in a statement reported by the official National News Agency.

Lebanon has been paralysed by an economic crisis that deepened as supplies of imported fuel have dried up.

The Lebanese currency has fallen by 90 per cent since 2019.

Many Lebanese normally rely on private generators that run on diesel, although that is in short supply.
