More than 100 homes in the Abingdon area have been without electricity this morning following a power cut.
The lights went out at about 9am this morning and Scottish and Southern Energy engineers are working to fix the fault.
A customer services spokesman said homes in three postcode areas including OX14 were affected.
Another spokesman said 68 homes in the Winterborne Road area lost power, which was restored by 10.30am.
However, a further 44 customers in the Park Road area are still without electricity.
Scottish and Southern Energy spokeswoman Lisa Marchi said: "We would like to apologise to all customers affected."
She added the company hoped to provide an update after 1.15pm.
