Street Light Project Objectives Reduce street lighting energy use and greenhouse gas emissions Improve street lighting performance and maintenance Enhance understanding of community attitudes and support for the program Develop financial models for street lighting alternatives. Development Street Lighting Service Agreement. Disseminate information

Issues 160 different tariff rates and line items for Coffs. Safety and risk management Capital Cost of lamps, fittings and poles. Ownership of lights, poles and fittings Capital cost met by different parties Lumen Depreciation Many lights operating well below 70 % efficiency Lamp survival/mortality. Colour Rendering Sensor/timer problems.

Issues Contestable street light energy from 1 Jan 2001 Mandatory Benchmarks and Non renewable Greenhouse Abatement Certificates Compatibility of existing fittings Inefficiencies of lights due to spill, and spread where light not needed. Capital depreciation terms Replacement terms for fittings Light pollution Inadequate street light performance monitoring Street lights records - location, type and age Light characteristics – glare, illumination, distribution. Availability and cost of long life high efficiency lamps. Compliance with Australian Standards 1158.1.3 & 1158.3.1 Efficiency loss due to insects, dirt etc

DULUX® T/E 57w & 42w IN Compact fluorescent lamps with Amalgam technology for applications with high ambient temperatures.

STREET LIGHT PROGRAM ACTIVITIES Audit of street lights - number, type, age, location Evaluate lighting alternatives. Street lighting trial in a residential area: replace MV with HPS; replace MV with LPS; evaluate & survey residents. Financial/Energy/Lumen modelling – Establish depreciated capital values; Calculate spot and bulk maintenance costs Management costs; Costs lamps, fittings, poles etc; Model capital eg loan, revised fees, one off payment, terms; Model terms for replacement progressive upgrading energy/greenhouse performance lighting performance

STREET LIGHT PROGRAM ACTIVITIES Enhance street light GIS data. Develop software model Develop specifications Prepare Service Agreement for upgrading and servicing. Prepare brochures and information Program commences.

Coffs Harbour Street Lights Annual Savings Retail Energy $25121 NUOS $30909 Capital $5242 Maintenance $30815 Total Ownership $92098 Greenhouse eCO2 tonnes 644 Ownership savings to pay out residual capital of $400,000

What this means: Regional Councils NSW (Country Energy)- COFFS HARBOUR - 35 % Energy Savings 644 tonnes less CO2 per annum 15% saving in street lighting costs Regional Councils NSW (Country Energy)- 24,000 tonnes less CO2 per annum Savings to Councils of $3,000,000 per annum

Steps to Introduce Energy Efficient Street Lighting Obtain Network Providers Database for your Council area Audit of physical assets against database Examine lighting alternatives relative to your own area, and consider issues such as available technology, temperature, pole heights and spacing, crime, and travel distances. Establish energy costs, maintenance costs, residual capital values and upgrade costs Input data and variables into Model

Steps to Introduce Energy Efficient Street Lighting Calculate cost/benefits for new and old lighting scenarios. Decide upon financing options for residual and new capital Keep your council informed and take advantage of positive media opportunities Investigate carbon trading Document CCP Greenhouse Gas abatement for compliance with Goals and Milestones Use savings – Greenpower, revolving funds.
