Northern Powergrid have been taking to the air to check the region's power lines and towers.

During the last seven months, Northern Powergrid has been using helicopters to inspect around 12,500km of power lines for signs of damage.

Pete Wilstrop said: “Patrolling our power network from the air allows us to detect potential problems before they occur.”

“These regular inspections ensure we can provide our customers with a reliable power supply.

“Our power lines are often located in isolated areas and have to stand up to rain, snow and high winds over the winter months.

“Checking them from the air is the best and most efficient way of making sure we can keep our overhead network in good working order. Any remedial work can be spotted and dealt with so we are ready for the winter months ahead.

“We fly our helicopter at speeds of around 30km an hour at low levels. Whilst there is some engine noise, the crew work hard to keep it to a minimum and reduce any potential disruption to local communities while they carry out these essential checks.

“Wherever possible we try to avoid areas where sensitive livestock is grazing.”
