Unison Commencing 3D Aerial Network Surveying Next Month

May 27, 2021 02:14 PM

Unison Networks is launching a comprehensive aerial helicopter survey of its full electricity network next month, using state-of-the-art technology - LiDAR (Light Detection and Ranging).

“LiDAR will enable us to build an extremely accurate 3D snapshot of the network, across Hawke’s Bay, Taupo and Rotorua,” says Unison’s General Manager of Networks and Operations, Jaun Park.

He says as the first time Unison is using the technology over such a large area, it will prove an invaluable tool for increasing the reliability of the network overall, as well as delivering on some of the Company’s other key areas of focus.

“It’s a very cost-effective way of getting a picture of the whole network all at once, and in a format we can readily use.

“Further to this, and importantly, LiDAR can reach challenging terrain, thereby removing the need for us to put field staff at unnecessary risk accessing these areas by vehicle and foot.”

The survey is scheduled to be completed throughout the month of June, with an extension into July possible if weather causes delays.

In accordance with New Zealand Civil Aviation Authority (CAA) rules and regulations, the helicopter will be operating at 1000 feet above urban areas and 500 feet above rural areas.

“At this altitude, we do not expect there to be any significant audible or visual impact on consumers or livestock, which is something we are always conscious of when carrying out aerial surveying on the network.

“The data accuracy of LiDAR is unsurpassed by conventional forms of measurement which serves as testament to our industry leading approach to delivering on customers’ energy needs.”

He says any members of the Hawke’s Bay, Taupo or Rotorua communities with queries or concerns are encouraged to call 0800 2 UNISON ahead of next month.
