These aerial patrols of over 5,500kms of the electricity network will allow trained observers to identify and record any signs of damage or wear and tear on the lines and equipment that carry electricity.
Alister Fenton from Northern Ireland Electricity said: “The power network in Northern Ireland has the highest ratio of rural overhead lines per customer in the UK, apart from the remote Scottish Highlands. We employ a helicopter as it is the quickest and most effective way of inspecting the lines and directing refurbishment crews to carry out further detailed checks and repairs.
“This work will help to improve the reliability and quality of service for our customers across Northern Ireland.”
The patrols will continue until March 2013. Any landowners with concerns about livestock or animals should contact NIE's Customer Helpline on 08457 643 643 for details of the inspection schedule.
