Thousands of homes in Bury St Edmunds were left without power this afternoon following a fault on a high voltage underground cable.
The incident affected 3,482 properties in the West of Bury and part of Horringer at about 1pm.
UK Power Networks engineers worked to return supplies to normal for 2,127 homes within 15 minutes and the majority had electricity restored by 1.35pm.
However, another 2,109 properties lost power at 1.50pm as a result of the fault and the situation was returned to normal by 2.10pm.
The cuts also hit many town centre shops, including Waitrose and T K Maxx, with some losing systems all day. There were also reports of cash machines retaining cards that were in them when the power failed.
Remaining households had their power supplies restored by 3.45pm.
A spokesman for UK Power Networks said: “We realise how difficult it can be without power and apologise for any inconvenience.”
