National Grid will share some of the excess cash it has made from electricity cables to Europe ahead of schedule as regulator Ofgem and others try to help keep bills pushed down.
The grid operator said it will pay £200 million to consumers over the next two years - the balance is normally settled every five years, but an unprecedented crisis in the energy markets meant the company and Ofgem thought it wise to make the payments earlier.
National Grid is not allowed to make more than a certain amount of money from its cables, so excess has to be paid back to consumers.
