Concern over a nationwide power shortage spiked after the National Grid issued a warning to all households in the UK.
The electricity network operator stated that it may struggle to match demand during Tuesday's - November 22- peak times from 7pm, reports the Sun. It means that some homes may suffer from blackouts, as many people switch on their appliances after a long workday. Despite the concerns, the National Grid quickly cancelled the warning - saying it had been triggered automatically.
The National Grid had planned to pay some homes to reduce their power consumption for an hour from 5:30pm from November 22, in a trial run of its new Demand Flexibility Scheme.

As temperatures continue to drop, the whole of the UK is going into the colder months with the tightest supply buffer in seven years.
After the National Grid recently said that they were confident that their reserves would be enough, the supply pinch was too close, and so the automatic alert was triggered for 7pm tonight.
Phil Hewitt, director at energy consultancy Enappsys, told the Daily Telegraph: "This is the first tight day of the winter but it is not super tight. It is a small appetsier of tightness, there will be much tighter days ahead."
A graphic from Enappsys has also been posted on social media, depicting the National Grid's supply margins. This explains that the the Capacity Mechanism Notice was triggered.
Following the concern, the National Grid said on Twitter: "The ESO is confident that electricity margins are sufficient for this evening. However, a capacity market notice (CMN) has been triggered by the automated system. CMN forecasts are issued automatically and are only based on information in the public domain. They do not take into account all the factors which our engineers are working on.
"The ESO has now withdrawn the Capacity Market Notice issued at 2:33pm today."
Even with reduced levels of energy, it is unlikely blackouts would happen, with the blip most likely in isolated areas with prior warning.
