The contractors currently working on the transformer in Ebden Street will be trying to switch it on tonight.
No specific time for the return of the power supply has been given yet.
Work has almost been completed but a test needs to be done to ascertain its functionality, Border Kei Chamber of Business’ Adre Bartis has indicated.
She has appealed to locals to use electricity with care and not to switch on aircons and extra appliances at the reintroduction of the power supply.
It was also possible that the power would be switched off again while the system was being tested.
