Millions of people were affected by major blackouts today after power cuts paralysed the nation causing chaos as homes, airports, traffic lights and trains were all left without electricity due to a 'failure of the National Grid'.

Areas including London and the South East, as well as the Midlands and the North West were all left without power in scenes described as a 'nightmare' by those caught up in the confusion.

The National Grid Electricity System Operator has revealed the outage was caused by a problem with two generators, but is still investigating. It is in touch with the National Cyber Security Centre which has said 'there is no evidence the issue was related to a cyber incident'.

Although the issue has now been 'resolved', there is still major disruption across the country. Those affected by the outages have described scenes of 'total and utter chaos' with one saying 'it was like witnessing something out of an apocalyptic film.'

While others joked 'have they tried turning it off and on again', as they tried to make light of a situation which left commuters having to disembark their trains and walk along tracks back to the station.

In London, commuters were plunged into darkness on the Victoria Line while traffic lights in Battersea lost power. All services out of London King's Cross were cancelled, and Thameslink trains were held 'at a stand' as British Transport Police confirmed they were assisting station staff and crowds.

Passengers were also left waiting on planes in Luton and Newcastle, with the former airport also affected by flooding this afternoon. In Ipswich, a hospital was left without power - as was St Mary's in Paddington.

Elsewhere, in Derbyshire, homes were left entirely without power with one resident telling MailOnline of burglar alarms going off and police sirens in the area. Another said they feared missing their honeymoon due to the travel chaos.

Concerned residents have reported power outages at their homes. One in Derbyshire told MailOnline: 'Our whole estate had all the burglar alarms going off, and there were a few police sirens.'

While Claire Wynn, who runs a PR company, also told MailOnline: 'We are heading off on our honeymoon in the morning on a holiday of a lifetime cruise with Royal Caribbean from Southampton and currently we are stuck on a train at Peterborough with several trains stuck ahead of us.

'Another train has been told to get on our train as well so it is overfilled, hot and cramped.'

'(I) realised that nothing was open and there was hardly any phone signal,' the 26-year-old said.

'All the traffic lights were down, but there were no police present, which meant it was dangerous to cross - cars weren't stopping either.

'It was like witnessing something out of an apocalyptic film.

'No one knew what was going on and, given it's a Friday afternoon, it's the last thing you want to encounter.'

And at a Sainbury's in London, people appeared to make off with free shopping, with an eye-witness saying: 'No one knew what to do. The staff just asked everyone to abandon their trolleys and leave.

'But with no security cameras or alarms, people were just leaving with all their shopping. Someone walked out with a hoover.'

Passengers at King's Cross Station in London were also affected, with Richard North saying: 'Would be interesting to know who will compensate the £120 taxi or the fines for collecting children three hours late from two separate childcare providers.

'Two children who were meant to be in bed an hour ago and we're still in a taxi.'

UK Power Networks, Western Power Distribution in the Midlands and Northern Powergrid all reported outages - due to a failure on National Grid's network.

Around 300,000 UK Power Networks customers were affected in London and the South East, a spokeswoman said and Western Power Distribution said around 500,000 people were affected in the Midlands, South West and Wales, with power restored to them all shortly after 6pm.

A spokeswoman for Northern Powergrid, which serves Yorkshire and the North East, said 110,000 of its customers lost power, while at least 26,000 people were without power in the North West of England, Electricity North West said.

Police have been drafted in to deal with the power cuts, which have stopped traffic lights in some areas of the country.

UK Power Networks tweeted on Friday evening: 'We're aware of a power cut affecting large parts of London and South East.

'We believe this is due to a failure on National Grid's network, which is affecting our customers.'

Paul was struggling with a similar problem, and wrote on Twitter: '#powercut and the worst thing is when it comes back on having to reset all the clocks again.' Advertisement

Commenting on the rail disruption, a Network Rail spokeswoman said: 'There was a power surge on the national grid this evening which means we lost power to all our signalling over a wide area, including the Newport, Gloucester, Ashford, Bristol, Eastbourne, Hastings, Three Bridges and Exeter areas.

'All trains were stopped while our back-up signalling system started up.'

Police in the capital could also be forced to man busy junctions after traffic lights failed.

A Transport for London spokeswoman said some traffic lights are 'not working' but the scale of the problem is not yet known.

Police officers could be called in to 'manage the busy junctions, to physically manage them themselves', she said.

'We're just assessing how many traffic signals are out.'

Scott McKenzie was travelling through Newcastle Airport when the power cut out for around 15 minutes, in what he was told by officials was 'due to a wider problem in the region'.

'Some of the spaces in the airport have little daylight - we were literally plunged into darkness and people were using their phones as torches to see and get around.'

Mr McKenzie said the problem at the airport 'seems to have been resolved' and Newcastle Airport said it is aware of the power issues but flights have not been disrupted.

'We have put in place alternative travel advice which is available on our website and National Rail Enquiries and on social media, and would urge passengers to check before they travel.
