18. 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

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.
