After a major power cut across Portsmouth on Monday, with further unrelated incidents on Tuesday and Wednesday, last night almost 200 homes in Southsea experienced further problems.
The main roads affected were Eastfield Road, Westfield Road, and Landguard Road.
Scottish and Southern Electricity Networks have confirmed they areÂ investigating the cause of the incidences and will be reimbursing customers who were affected on Thursday up to Â£25 per person.
AÂ spokesmanÂ said: '˜SSEN would like to apologise to customers in the Southsea area for the persistent issues with low voltage and intermittent power interruptions over the last few days, including yesterday evening.
'˜There were 186 customers affected by last night's interruption with engineers attending the site promptly and power restored to all customers by 11pm.Â
'˜This included action to reconfigure the local network which will help maintain voltage stability. We have multiple teams on site today to identify the underlying cause behind the localised issues and progress a long-term repair, which is our priority.
'˜We recognise this is a frustrating situation for our customers and, as a gesture of goodwill, have offered to reimburse the cost of a hot meal, up to Â£25 per person, for anyone affected by Thursday night's fault.
'˜Our customer and community advisors have visited residents directly and we would encourage any customer who would like to discuss the situation to call our power cut helpline, 105.'
