Approximately 40,000 luminaires are scheduled to be replaced during the first three years in the accelerated LED upgrade program. The replacement program will maximise maintenance savings because intervention costs, such as the need to re-attend sites, will be reduced, especially on major and arterial roads with traffic management issues. There are benefits in targeting main roads because of the high-power lamps and the energy savings that can be achieved in these areas. Over the life of the contract, energy costs will be reduced by 40 per cent.
The contract will see the use of the highest quality light fittings, with 20-plus years of expected useful life. This will result in reduced operational and maintenance costs for the territory well beyond the completion of the seven-year contract period.
The last aspect of the contract is focused on implementing smart lighting functionality. Smart digital controls will be implemented as part of the energy efficient LED replacement program. This will include the installation of smart nodes at each upgraded LED luminaire and the establishment of a mesh communication network.
The smart city backbone provides opportunities for the trial and potential adoption of a wide range of smart devices, such as smart traffic controls and sensors, and may allow the network to interact with smart water, gas or electricity meters in the future.
The control maintenance management system, CMMS, will self-diagnose defects and enable optimised maintenance. The smart system will be focused on smart lighting controllers that will collect data from all the lighting points and also calculate, generate and distribute alarms to maintenance teams when needed. Energy consumption will be measured and reported accurately for each light point.
Customers will also be able to see the job status of streetlight defects. The implementation of the smart digital controls will mean that more streetlight defects will be detected and repaired before members of the public lodge a request for service.
LED lights also provide an output that is highly directional. A higher percentage of light can be directed towards where it is required, resulting in less wasted and nuisance light.
Madam Speaker, in addition to the performance outcomes I have just spoken about, this project will deliver significant cost savings and reduce greenhouse gas emissions through reduced electricity consumption.
The streetlight energy performance contract is a lump sum payment of $13.5 million per annum over seven years, totalling $94.5 million. The estimated cumulated guaranteed energy saving is over 110 million kilowatt hours over the seven-year period, an estimated cost saving of around $20 million. In addition, the LED replacement and smart lighting program’s operational and maintenance savings are expected to grow to approximately $2 million per annum by the final year of the contract.
These self-funded upgrades will save the ACT taxpayer money and allow for the development of an improved and higher quality streetlight network that will support
