Ofgem has said "companies could have done more" to help customers during last year's winter storms, when power cuts affected nearly a million homes.
Ofgem's Maxine Frerk said:
A power cut at Christmas time is the last thing anyone needs.
While we recognise the hard work of the companies and their staff who were out working to reconnect customers during the severe weather, the companies could have done more to plan for the weather and keep customers informed.
The energy regulator is to more than double the minimum compensation payment for households that suffer power losses due to severe weather.
Ofgem said the planned changes should "strengthen the incentives for companies to act quickly" and reconnect customers as soon as possible.
