Hundreds of homes in the St.Johnston and Raphoe areas are without power in what is suspected to be a major fault in the area.
Homes have been without electricity for the past hour while ESB crews battle to fix the fault.
One elderly resident said he was hoping the power supply returned as soon as possible.
“Luckily I have a supply of candles but I didn’t have the fire on. I had the oil on but that’s out now.
“IT’s getting cold so hopefully it will return soon. Nobody seems to know yet,” he said.
