A power cut has impacted a large area of Hertfordshire and parts of London and Bedfordshire.
Towns in Hertfordshire were plunged into darkness at around 7pm today (Thursday, March 24), with street lights off in St Albans and Hatfield.
According to UK Power Networks' power cut map, the incident was resolved at 9.43pm.
UK Power Networks said that more than 5,000 properties were impacted in 68 postcode areas.
Residents took to social media to share their experiences.
One Twitter user wrote: "Power cut for the whole of St Albans.
"No street lights, traffic lights. All shops and restaurants dark.
"This is... dystopian."
Another wrote: "Houses all dark between Hatfield and Welwyn Garden City."
A restauranteur said: "Our restaurant in Potters Bar EN6 has diners sitting in the dark trying to eat."
They added that power has now been restored to the restaurant, but some of the computer systems remained offline.
Residents also reported issues with their mobile reception.
On the railways, Thameslink and Great Northern reported disruption to their networks.
St Albans City station was closed due to a lack of power, with trains unable to stop.
The closure has now lifted and trains are calling at the station, with compensation available for passengers who have been delayed by 15 minutes or more.
Great Northern and Thameslink trains were earlier unable to call at Potters Bar, Brookmans Park, Welham Green and Hatfield stations, but the service has since resumed.
An earlier statement read: "If you are travelling to or from one of these stations and have not begun your journey we strongly advise delaying your journey until the issue is rectified."
UK Power Networks has been contacted for comment.
Is compensation available after the power cut?
A statement on the UK Power Networks website notes that compensation is not usually available if a power cut last for 12 hours or less.
The statement reads: "We’re sorry you had a power cut, we know they are inconvenient and we always work to get your power back on as soon as is safely possible.
"If you have had a power cut lasting less than 12 hours then unfortunately we wouldn’t normally offer you a payment."
A similar arrangement applies to businesses, where compensation is normally only available for power cuts lasting 12 hours or more.
A UK Power Networks statement reads: "Power cuts occur for many different reasons and usually without warning, so we’re not liable for any loss or damage.
"Your business insurance may cover you so please check with them.
"Most insurance companies will contact us directly if they require further information."
