The Dunedin City Council (DCC) has selected Telensa as part of a contract with Broadspectrum to upgrade it’s street lighting network.

There are approximately 15,000 high-pressure sodium streetlights on the Dunedin streetlight network. These lights are reaching the end of their useful life and are being converted by Broadspectrum to Light Emitting Diodes (LEDs), which will be wirelessly connected and managed by Telensa’s PLANet system.

PLANet will give DCC control over lighting levels with the lights remotely tailored to suit each location in Dunedin. PLANet is an end-to-end intelligent street lighting system consisting of wireless nodes to connect individual lights, a dedicated network owned by the city, and a central management application. The system will support the LEDs in reducing energy and maintenance costs, while improving the efficiency of maintenance through automatic fault reporting, and turning streetlight poles into hubs for smart city sensors. 

Richard Saunders, group manager transport at Dunedin City Council, said: “This project shows our commitment to intelligent infrastructure and how we’re delivering a safer, more cost-effective service environmentWe’re excited to be working with Telensa and Broadspectrum to make our streetlights smart and to create a platform to deliver smarter, more joined-up services to our residents in the future.”

Domenic De Fazio, chief executive urban infrastructure at Broadspectrum, said: “With more than 1.7 million lights already connected, we are confident that working with Telensa will help us to achieve world-class lighting for the city of Dunedin.”

This project is 85% funded by the New Zealand Transport Agency and work is expected to take 18-24 months. The Transport Agency is fast-tracking co-investment with local authorities in LED street lighting and controls.

“Cities across New Zealand are increasingly adopting wireless control systems for their streetlights – reaping significant environmental, cost and maintenance benefits as well as providing a platform for future smart city applications," said Will Gibson, founder and chief commercial officer at Telensa.

Policy changes in 2015, means local authorities can replace existing road lights with LED and controls immediately, rather than wait until they reach the end of their useful life. As a result, a number of other conversion programmes have already started including WellingtonWhakatane, Upper Hutt, and more. 

"Following our projects with Whakatane and Wellington, we are delighted to now also be working with Broadspectrum and Dunedin City Council to bring these capabilities to yet another city in New Zealand.”
