Our LED lighting network with smart controls underlines the city’s focus on smart technology.
In total, the Council owns 38,000 lights in its road network, and 4500 are already LED.
The timing for the replacement of the remainder will be considered as part of the upcoming 2018-28 Long Term Plan.
Over the 20-year lifespan of the LED lights, we will save $32 million – or $1.6 million per year – on the electricity and maintenance costs involved with the old form of lighting, once all of the lights are replaced.
We expect maintenance costs to drop by about $600,000 per year and energy use by about $1 million. The conversion of all street lights is expected to cut carbon emissions by about 1,500 tonnes per year.
The central control system provides real-time energy monitoring and additional savings, and each light can be controlled individually.
A central system also allows better detection of problems and faster responses to any failures.
In addition to the financial benefits, LED lights produce 50 to 70 per cent in energy savings.
LED lights also offer a directional source, focusing the light downwards and reducing light spill or pollution.
