The UK's energy watchdog will call on the public to cut how much gas and electricity they use this winter to guard against the risk of shortages.
Ofgem is set to launch a campaign to show people how to reduce energy use.
Ofgem boss Jonathan Brearley is expected to say that a supply emergency is unlikely.
But he will also warn the coming months could be "difficult" and "we cannot at any time, particularly this winter, eliminate all risk".
The initiative, set to be launched in a speech later on Thursday, comes as the government appeared to change direction on its own public information campaign to cut energy bills.
Last week, cabinet minister Nadhim Zahawi said a planned £15m government drive to encourage household energy-saving had been dropped because the National Grid and Ofgem were running similar campaigns. But the BBC also reported that the campaign had been shelved after opposition by Prime Minister Liz Truss.
At Prime Minister's Questions on Wednesday, however, Pensions Minister Guy Opperman asked Ms Truss about having a nationwide mailout campaign on cutting energy usage.
She said that the Business and Energy Secretary, Jacob Rees-Mogg, "is working on a plan to help companies and individuals use energy more efficiently", adding: "I hope we'll be able to start this going in Number 10 straight away."
