Street Lighting

8 Street Lights: Energy Use & Emissions 1.3% of all end-use electricity in the EU25, or 35 TWh per year 1 1% of all end-use electricity in the USA 2 10% to 38% of a municipal governments electricity consumption and greenhouse gas emissions 3 1: P.

9 Street Light Retrofits: Potential for 35%-70% Energy Savings and Significant Emissions Reductions Greater energy efficiency from advanced luminaires and integrated control systems –35-60% savings vs. high-pressure sodium vapor streetlights –70%+ savings vs. mercury vapor streetlights –additional 10-20% savings with integrated system controls Lower maintenance costs –Luminaire life expectancies significantly longer Short payback –3-7 years, depending on replacement technology and pre-existing infrastructure Reduced GHG emissions –For a city with 150,000 streetlights, potential to avoid >40,000 tons of CO 2 emissions per year, assuming US average.600kg CO 2 /kWh Outdoor Lighting Program

10 Advanced Street Lighting Deployments Outdoor Lighting Program CityTechnologyProject Description Ann Arbor, Michigan LEDIn 2007 installed 1,400 56W LED street lights to replace 100W HPS streetlights; each LED unit cost $460; energy savings of >50%; payback in 4.4 years Anchorage, Alaska LED, InductionIn 2008 initiated replacement of all 16,500 City street light fixtures with LED; Expected energy savings of >50% from a full retrofit of all 16,000 street lights; $2-3MM annual O&M savings forecast. Simple payback of <7 years for retrofit. Oslo, Norway Intelligent Control System and Electronic Ballasts In 2007 began to equip its 55,000 HPS streetlights with an intelligent control system and electronic ballasts; has achieved 62% energy savings to date These are only three of many successful projects; CCI will help its partners leverage these cities experiences in lighting retrofit projects.

18 Obstacles Particular To Street Light Retrofits ObstacleWay To Resolution Concerns about efficacy of new technology Share experiences of early-adopters, including equipment specifications and operating data, to demonstrate technology viability Present several energy-efficient alternatives with sound warranties to enable choice from a menu of options Misaligned incentives to retrofit –Utilities own assets –Utilities set rates Involve lenders to propose alternative project financing structures and equipment ownership structures that untangle conflicting incentives Limited budget for large project Again, involve lenders to propose project financing structures to minimize debt burden on city Encourage consolidation of project onto one contract to enable scale-up beyond a single years budget Standards do not fully capture benefits of new technology Optimize street lighting system according to current lighting standardsreduce over-lighting, and prioritize quality of light over quantity of light Encourage reevaluation of current lighting standards through projects enacted by early adopters Outdoor Lighting Program

19 Fixture Technology Options, Pros and Cons TechnologyMercury VaporHigh Pressure Sodium Vapor InductionNew Ceramic Metal Halide LED Relative Age Description Older, very common high-intensity discharge (HID) technology that generates a bluish- white light Orange-hued HID light source commonly used to displace less-efficient mercury vapor street lights. White-light electrodeless light source with long operating life White-light HID technology; new CMH fixtures with electronic ballasts are >35% more efficient than previous CMH systems New, white-light technology that uses arrays of LEDs small, directional light sources to illuminate areas. Pros Low initial cost Longer lamp life (~24K hrs) White light Sudden failures are uncommon Low initial cost Longer lamp life (~24K hrs) High lamp efficacy (~115 lumens/watt) Long life (100K hrs) White light Low maintenance cost High fixture efficiency due to electronics White light High lamp efficacy (~115 lumens/watt) High fixture efficiency due to electronics and tighter optics around smaller lamps Long life (>50K hrs) White light High uniformity High fixture efficiency due to electronics and directional LEDs Cons Poor lamp efficacy (~40 lumens/watt) Lower fixture efficiency Orange light High initial cost Lower lamp efficacy (~75 lumens/watt) High initial cost Shorter lamp life (~20K hrs) High initial cost Lower LED efficacy (~75 lumens/watt) oldestnewest Other technologies not profiled include linear fluorescent, compact fluorescent and incandescent street lights Outdoor Lighting Program

20 Common Steps Toward Enacting a Retrofit Project Outdoor Lighting Program Define High-Level Project Goals Survey Staff Resources & Expertise Conduct System Audit Prepare and Vet Economic Model Communicate Project Opportunity Receive and Review Proposals Approvals Process Identify lighting engineers with system expertise and interest in a retrofit project Collect data on street lighting system inventory, ownership structure, incentives to retrofit, stakeholders, This model will capture the complete economics of a retrofit, to help decision-makers determine whether a project is feasible Share economics with lending institutions, contractors and manufacturers (if appropriate under local procurement rules) to generate proposals Analyze various proposals for financing and realizing a retrofit Begin defining project proposal for internal approval; generate final requirements and purchasing specifications Prioritize among improved safety, enhanced performance, reduced energy use, many others
