Intelligent Power supplies SLI Program [AUSGRID] Briefing for Leichhardt Council 3 August 2011...

Councils pay Ausgrid $40m+ per year for lighting capital & maintenance charges + $17m for energy & network charges..

Improved technology & maintenance approach being jointly considered with Ausgrid with the aim of reducing energy consumption and controlling costs:
§ Active Reactor HPS
§ LEDs
§ Induction
§ Cosmopolis / metal halide
§ Intelligent controls / remote monitoring

...Public Lighting in Leichhardt § Approx Ausgrid 3,900 lights in LMC ( .. § 95% funded, owned and maintained by Ausgrid .. § 5% funded by Council/3rd parties but ‘owned’ & maintained by Ausgrid .. § In addition, Council manages some lights directly)
§ 1 per 13 residents or 350 lights/km2
§ $930,000+ spend in 2011/12 by LMC ( .. § Average split of costs is 15% energy, 15% network distribution and 70% capital & maintenance)
§ Energy consumption is more than 2.3 million kWh/yr (with consequent GHG emissions of more than 2400 t CO2/yr)..

LEDs § White light, long life & high efficiency
§ Politics ahead of engineering but rapidly evolving and will emerge as key lighting source
§ US DOE CALIPER program suggests that only 30% of manufacturers’ claims can be substantiated
§ Current barriers include:
.. § Lack of energy efficiency benefits in some contexts
.. § High (but declining) capital costs (~2-3 times more expensive)
.. § Lack of proven reliability & questions about power supplies
.. § Concerns about glare
.. § Compliance with AS1158
§ Pilot proceeding with Ausgrid at 8 sites
§ Status internationally - generally at trial stage but with a handful of large deployments

Induction
§ Fluorescent technology without electrodes
§ High colour rendition and incredibly long life (up to 100,000 hr rate life)
§ Efficient but less likely to see further improvements
§ Most deployments in US & China

Metal Halide / CosmoPolis § High colour rendering, good efficiency, ‘white’ light but lower reliability
§ Utilities reluctant to use but reliability
§ CosmoPolis is Philips variant of metal halide
§ Ausgrid trials underway
§ Most deployments in EU and currently costly in Australia

Off-Peak Dimming / Remote Monitoring § Integral electronic controls and communications to remotely monitor & control lights
§ Dim based on traffic, weather & light levels
§ Off-peak dimming typically by 30-50% between midnight and 5am
§ Application of dimming may be limited in Australia because of lower lighting levels
§ Remote monitoring attractive ...www.leichhardt.nsw.gov.au
