  2. PHI LED STREET LIGHT PILOT PROJECT • Project Overview • Background • Objectives of Pilot Project • Selection of Pilot Locations • LED Manufacturers • Implementation Plan • Q&A

  3. PHI LED STREET LIGHT PILOT PROJECT • Background • 2007 PHI Distribution Standards 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 Technologies; a third manufacturer, eLumen, was identified in 2008. These three LED lights were installed at our Rockville Service Center in 2008 for evaluation. • Additional LED manufacturers are introducing their products. BetaLED and LED Roadway Lighting has submitted a sample for installation; Howard Industries Lighting Division and Holophane have recently introduced cobra head models.

  4. PHI LED STREET LIGHT PILOT PROJECT • LED Demonstration Area – PHI has installed several LED cobra head fixtures in the Rockville Service Center parking lot as a staging area for displaying this emerging technology to our local communities and jurisdictions.

  5. PHI LED STREET LIGHT PILOT PROJECT • Objectives of Pilot • Investigate LED technology in a cobra head application to replace inefficient incandescent 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

  6. PHI LED STREET LIGHT PILOT PROJECT • 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 • Long Life Photo Cell • Gain customer interest and input: • Glare issues • Coolness of light for high color temp fixtures • Compile information, determine viability of this technology, publish report and potentially establish tariff rates.

  7. PHI LED STREET LIGHT PILOT PROJECT • Selection of Pilot Locations • Pilot Locations selected to meet set criteria • Establish pilots prior to upcoming Holiday Seasons to attract a large number of visitors and gain wide public interest. Select public areas with high visibility which attract larger volumes of people - retail/dining locations, gathering places, and close proximity to Metro. • Limit pilots to areas which can physically handle increased traffic levels due to advertising these pilot locations for public feedback. • LED Pilots to be established in both Pepco counties and all PHI regions. • Pepco – Two (2) pilots in Montgomery County & two (2) in Prince George’s County. • DPL - Pilots in each of two(2) Districts in the PHI Bay Region and two (2) Districts in the New Castle Region TBD. • ACE – Pilots in four(4) Districts in New Jersey. • Each pilot location to consist of ten (10) LED lights.

  8. PHI LED STREET LIGHT PILOT PROJECT • LED Manufacturers • For first pilots, Pepco 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 (typically 70W HPS & 100W MV). • LED Manufacturers for initial pilots in PHI • Elumen - Modular design and Intelligent Electronic Driver • Lighting Technologies - Lightweight fixture; early production • LED Roadway - Solid state design • BetaLED - LA/Clinton initiative; available in variety of wattages • Sternberg

  9. PHI LED STREET LIGHT PILOT PROJECT • Implementation Plan • Select LED fixtures to be installed and evaluated in the selected municipalities for a six month pilot. • Execute a Memorandum of Understanding (MOU) between the selected municipalities and PHI to address billing, objectives of pilot project, ownership of equipment, possible outcomes, etc. • Begin pilots in fourth quarter of 2009 across PHI. • 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. • Establish tariff rates for LEDs based on information learned from pilots.
