A power cut hit 1,500 homes in Havant, Leigh Park and Rowlands Castle this morning.
Southern Electric Power Distribution says a fault on the network at 5.10am caused the problem.
Within twenty minutes of the loss of power being identified, engineers isolated the network and ensured the number of properties affected went down to 66.
That has now gone down to 11 and the energy company has identified the fault was caused by an overhead cable.
Engineers are carrying out repairs and it’s hoped everyone’s power will now be back by noon, rather than by 9am as originally anticipated.
Thomas Nicoll, a spokesman for Southern Electric Power Distribution, said: ‘It’s never good when people lose power, and that has happened overnight.
‘But thankfully we have managed to restore some power quickly and hope to get all the power back up in the next hour or so.’
