Meet the sniffer dog who helps find energy leaks deep underground and keep power flowing

SP Energy Networks, which covers the north of the county, has been trialling the use of specially trained detection dog Jac.

He is able to find faults on the power network deep underground, by smelling oil and hydrocarbon gases through earth and tarmac before pinpointing the fault by pointing with his front paw.

While cables are typically buried at 40-80cm, Jac has been known to discover a fault two metres deep and his sensitive nose can sniff out as little as a couple of drops of oil.

Scott Mathieson, of Spen, said Jac boasts a 100 per cent success record – and he loves his job because he gets a treat each time.

The dog is being used to help find some of the network issues that could lead to power cuts.

Mr Mathieson said: “Part of keeping the lights on in an electricity network involves investing in innovation and technology.

“We’re used to using laser technology, flying the network with drones, but Jac adds to our armoury significantly.

“He is a sniffer dog and we’ve been piloting using Jac to help us detect cable faults in particular.

“So when cables fail, if they’re oil filled, they let off some oil that lets off hydrocarbon gases or the insulation breaking down lets particulate levels of hydrocarbons off.

“Jac is a springer spaniel whose sense of smell is thousands of times more effective than a human being, and he can detect exactly where the cables have a weakness in them.

“The benefit of that is that we can repair the cable actually before it fails and improve customer experiences.”

The pilot, which is continuing, is one of a number of measures Spen is taking to prepare for the winter weather.

The network operator already expects to see fewer faults needing to be repaired thanks to an innovative system that can spot potential problems before they even happen.

A new Low Voltage Support Room is using advanced monitoring technology to provide real-time information on supplies across its operating area north and south of the border, in what Spen said is a UK first.

It analyses data produced by smart meters and electricity substations to highlight where a potential fault might occur on the network, helping engineers find exact locations where repairs are required, sometimes before power drops and customers are even aware of an issue.

Meanwhile, inspections of the poles and wires that transport electricity around the country continue all year round.

SP Energy Networks is responsible for 65,000 miles of network and 30,000 substations.

The normally storm-resilient network was severely damaged in places when Storm Arwen brought winds of over 110mph in places last November.

Mr Mathieson said: “In general, we’ve have seen around 25 per cent fewer faults caused by winter weather than a decade ago, which is down to the investment in making the network more resilient.

“Storm Arwen was unlike anything we have seen in recent memory with wind speeds last measured as high in the 1950s. However, it’s a stark reminder of the impact extreme weather can have and the unplanned outages that can result.

“When weather-related power cuts happen, we will work around the clock to get supplies back on but we always encourage our customers to be prepared just in case.”

SP Energy Networks is also reminding all customers ahead of the winter season to ensure they keep the national 105 emergency power cut number close to hand so they can call them if their power does go out unexpectedly - no matter who they pay their bill to.
