Households will see an average of £12 a year come off their bill under price control plans for the companies that run Britain's local electricity network.
Energy network companies will have to pay £17bn to upgrade and maintain the network under proposals put forward by industry regulator Ofgem.
Ofgem sets price controls for the companies to limit the amount they can collect from customers' bills and incentivise them to improve their services.
The regulator rejected price control plans from five of the six energy distribution companies, saying they did not represent value for money for consumers.
