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.

10
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

What this means

• 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

31
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

32
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.
