Randwick Council manages around 10,000 public and streetlights with energy consumption from streetlights accounting for half of Council's overall stationary energy consumption. The cost for running and maintaining those streetlights is around $1.5 million per year.
Street lighting Improvement Program
The Street lighting Improvement Program (SLI) is an initiative between Southern Sydney Region Organisation of Councils (SSROC) and Sydney Councils to work with Ausgrid, who own the streetlights, to address sustainability issues including services, technology and pricing.
The SLI program has adopted two approaches for improving street lighting efficiency:
Adoption of Light Emitting Diode (LED) lights for residential roads
The current residential street light will progressively be converted from its existing Compact Fluorescent Lighting (CFL) or Mercury Vapour (MV) lighting to an energy efficient LED light. This switch will generate savings of around 20% of total lighting costs for Randwick and around 60% in energy consumption for residential road lighting.
Adoption of Active Reactor High Pressure Sodium (HPS) lights for main roads
The existing main road lighting will be changing over from MV lamps to HPS lights. This changeover will contribute to a 20% in lighting costs for Randwick and around 50% in energy consumption.
The adoption of the energy efficient streetlights for both the main and residential roads, which account for 80% of the street lighting inventory, will help Council save up to 50% of our street lighting energy consumption and generate an overall cost saving of around 30%.
