People in the UK have been warned to prepare for planned blackouts this winter.
The National Grid ESO warned that in the even of a gas supply shortage, it may be forced to impose three-hour power outages early next year which could see people without electricity for hours on end.
With the power going off, there is a chance the surge of electricity coming back may cause some plugged in appliances to be damaged, the Mirror reports.
And some everyday essentials that should remain unplugged during these blackouts include televisions, irons and home computers.
According to the Sun, people should wait until after the outage is over before plugging these back in.
If the blackouts do happen they would be on weekday evenings in January and February when it is particularly cold, according to National Grid boss John Pettigrew.
As a result it may be important to unplug the essentials before heading to bed in case appliances are damaged while people are sleeping.
At the Financial Times' Energy Transition Summit, Mr Pettigrew admitted fuel for Britain's power stations, which generates most of the nation's power through gas, could be scarce by January in the worst case scenarios.
This would mean blackouts could happen on "really cold evenings" between 4-7pm in January and February.
To prepare, people are being urged to keep their torches on hand and stock up on batteries so that they can get through the hours of darkness.
Candles are also a popular choice for lighting up the dark nights, but experts have warned that these could pose safety risks.
It's not yet been confirmed if the blackouts will definitely take place. They would depend on a number of different factors, such as whether the UK fails to secure enough gas from other countries in time for the new year - especially if the country experiences colder weather than expected.
This is combined with lower than usual wind speeds for wind turbines and restricted electricity imports via subsea cables from other European countries such as Belgium, France and the Netherlands.
If they do go ahead, any plans will need to be by the Government and King Charles before they could happen.
A Government spokesperson said: "The UK has a secure and diverse energy system.
"To strengthen this position further, we have put plans in place to secure supply and National Grid, working alongside energy suppliers and Ofgem, will launch a voluntary service to reward users who reduce demand at peak times."
