8. 8 The Retrofit Opportunity Catalysts Rising energy prices Climate change goals Enablers Emerging technologies LED Induction Control Systems Competitive financing Reduced energy bills Avoided greenhouse gas emissions Reduced maintenance costs Decreased light pollution Enhanced visibility and performance Near-Term Benefits

9. 9 Potential for 35-70% Energy Savings Outdoor Lighting Program Lower energy costs »35-60% savings vs. high- pressure sodium vapor fixtures »70% savings vs. mercury vapor fixtures »10-20% additional savings with controls Lower maintenance costs »Luminaire life expectancies significantly longer »Integrated system controls help optimize maintenance delivery Reduced GHG emissions »For a city with 150,000 streetlights, potential to avoid >40,000 tons of CO 2 e/year

10. 10 Advanced Street Lighting Deployments Sharing best practices: leverage other cities’ project experience Outdoor Lighting Program

11. Anchorage LED Retrofit Program Outdoor Lighting Program Total Street Lights: 16,500 Fixture Wattages (HPS) »150W — Residential »250W — Collector Roadway »400W — Arterial Roadway

12. Total Capital Outlay$2,199,471 Annual Savings$350,000 Energy Efficiency>50% Payback Period7 Years Net Cumulative Cost Savings $2,837,390 Anchorage LED Retrofit Program: Phase I Outdoor Lighting Program Phase I Key Figures Phase I Retrofit »4,200 150W and 250W HPS Fixtures

13. Resident Survey of New Fixtures Outdoor Lighting Program Residents overwhelmingly approved white light over existing high-pressure sodium system Two Resident Surveys: March and December 2008 »130 male and female residents ages 17-71 »Tested 2 kinds of white light technology »Also tested dimming systems / centralized control

14. 14 Announced February 16, 2009 98% of fixtures to be retrofitted will be HPS City will tender in small, discrete increments to allow for technology innovation Largest LED retrofit project ever undertaken Los Angeles LED Retrofit Program Photos courtesy of the Los Angeles Bureau of Street Lighting – Before and After shots of 6 th Street Bridge LED Retrofit on 8/25/09.

15. 15 Los Angeles LED Retrofit Program Outdoor Lighting Program Estimated Total Project Cost $57 million Projected Annual Energy and Maintenance Savings ($, post retrofit) $10 million Projected Annual Energy Savings (kWh, Post Retrofit) 68,640,000 kWh / year Projected Annual CO2 Savings 40,500 t / CO2 / year Installation Timeline 5 years Expected Payback 7 years Replacement of 140,000 city street light fixtures with LED fixtures and installation of remote monitoring system.

16. 16 Obstacles Particular To Street Lighting Projects Outdoor Lighting Program Concerns about efficacy of new technology Limited budget for large projects Standards do not fully capture benefits of new technology

17. 17 Retrofit Roadmap Define High-Level Project Goals Conduct System Audit Select replacement technologies *Plan and deploy a small scale pilot test Conduct detailed economic analysis Craft business case for full-scale implementation Navigate local approvals process Evaluate existing equipment and define opportunities for system improvement Review projects that have tested and deployed these technologies Include objective and subjective evaluations *Optional, if no other tests are relevant. Conduct assessment of local finance options available to your municipality or utility Analyze various proposals for financing and realizing a retrofit Generate final requirements, purchasing specifications, and finalize finance plan Commit to goals, timeline, and necessary staff resources Outdoor Lighting Program
