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

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
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.
