Delmarva Power LED Street Light Pilot Project 1
AGENDA Background Objectives of Pilot Project Selection of Pilot Locations LED Manufacturers Implementation Plan 2
Background 2007 Utility Distribution Standards employees began researching LED Technology for roadway use. Information obtained from pilots in the City of Ann Arbor, Michigan and Toronto, Canada identified two manufacturers - Relume and Lighting Technology (Leotek); a third manufacturer, elumen, was identified in 2008 for evaluation. Additional LED manufacturers are introducing their products. BetaLED has submitted a sample for installation; Howard Industries Lighting Division and Holophane have recently introduced cobra head models. 3
Objectives of Pilot Investigate LED technology in a cobra head application to replace existing lights, and also to replace High Intensity Discharge (HID) lighting as it is phased out in the future. LED evaluation criteria would verify the following: Power consumption Ease of installation Lumen output Quality of product Luminaire life rating Input from customers Compile information, determine viability of this technology, publish report and potentially establish tariff rates. 4
Objectives of Pilot (cont.) Identify standards to ensure uniform performance and product criteria. (i.e. IESNA RP-8-00). Look to manufacturers to identify various issues which can affect uniformity of product. Lumens per watt release Agreed-upon wattage classifications Dark Skies compliance Heat dissipation/management Warrantees for premature failure Gain customer interest and input: Glare issues Coolness of light for high color temp fixtures 5
Pilot locations selected to meet proposed criteria: Select area that can establish pilot and product comparisons within a compact area Select an area that may contain vehicular traffic, pedestrian traffic, limited/no tree intrusions, etc. Select area that proposes safe working conditions for employees while light products are installed and tested LED Pilots established in four Delmarva Power regions City of Wilmington Town of Elkton Town of Chestertown Town of Georgetown Each pilot location to consist of ten LED lights representing two different manufacturers. 6
For first pilots, Delmarva Power is working with several LED manufacturers to provide a variety of fixtures currently available Primarily focused on cobra head fixtures to replace existing incandescent and HID lighting (MV and HPS). Selections based on ability to meet lumen output and light patterns/distribution for replacement of existing fixtures 7
LED Demonstration Area Delmarva Power has installed several LED cobra head fixtures on Broom Street between Concord Avenue and 23 rd Street. LED photos are illustration only. 8
Implementation Plan Select LED fixtures to be installed and evaluated for about a six month pilot. Execute a Memorandum of Understanding (MOU) between the selected municipalities and Delmarva Power to address billing, objectives of pilot project, ownership of equipment, possible outcomes, etc. Begin pilots in 2010 Sign boards to be installed at each location announcing pilot and pointing to information & questionnaire on website. Publish results of pilots and share information with customers and others; determination to be made moving forward. Evaluate performance, review feedback, consider tariff rates for LEDs based on information learned from pilots. No firm dates established for LED implementation in Delmarva Power. 9
