Turkey's Karpowership, which provides electricity to Lebanon from two barges, said on Friday it was shutting down supplies over payment arrears and after a legal threat to its vessels in the country, which is in the midst of a deep economic crisis.
The company, which supplies Lebanon with 370 megawatts (MW) or the equivalent of about a quarter of the country's current supply, had told the government this week that it would have to take the step if there were no moves to reach a settlement.
The company said in a statement it was shutting down the power supply on Friday, and a source familiar with the situation said the measure was taken around 8 a.m. (0500 GMT) as fuel on the vessels had run down.
Lebanon has been without a functioning government since August, with political leaders deadlocked or complacent as the country hurtles toward total collapse. Fuel supplies are running out, leaving the country at risk of plunging into total darkness as power stations and generators run dry.
The current economic crisis is unprecedented in Lebanon's modern history.
