High winds and stormy conditions have left 100,000 properties in the East of England without power.
UK Power Networks said its engineers had been working through the night and were continuing today to try to repair the damage and restore electricity as quickly as possible.
The company is carrying out helicopter patrols in the region to check overhead power lines and staff are working with volunteers from the British Red Cross to support people in the worst affected areas.
A power company has been fined £275,000 over the death of a worker in an explosion at an electricity sub-station in Chelmsford. John Higgins, who was 59, died from 95 per cent burns and inhaling toxic fumes after the blast in May 2008. Serena Sandhu reports.
