A power cut disrupted flights and terminal services at Edinburgh airport this morning.

The electricity is believed to have failed just before 9am.

The airport said the power “was now returning” but flights have been disrupted and passengers should expect further delays.

The power cut affected the terminal building and the main hall was plunged into darkness with only emergency lighting available for almost an hour, the BBC reported.

It was not possible to provide the usual ground services such as check-in or security during the outage.

An airport spokesman said: “We can confirm that power is now returning to the terminal and that flights have resumed.

“We’re working to allow passengers to continue their journeys in a safe and ordered manner and we thank passengers for their patience whilst we do this.

“As always, the safety of passengers and staff is our priority. We expect there to be further delays whilst we clear the backlog.”

Hundreds of passengers inside the terminal were advised to be patient while engineers worked to restore power.

Those planning to fly later this morning are being advised to come to the terminal building as usual.

Miranda Hurst, from Edinburgh, who is due to fly to London, told the BBC Scotland news website, said: “I was on the airport bus when we were told the bus couldn’t go any further as there had been a power cut so the barrier could not be lifted.

“So we had to walk. When I arrived at the terminal the lights were off and nobody knew what was happening.

“I’m in a queue at the arrivals exit as we cant go upstairs as there is no security as they cant scan anything.

“The Tannoy has been affected too so they cant communicate anything to us. They have started handing out water to us.”
