2 AGENDA Program Update LED Streetlight Conversion Next Steps New Technology Remote Monitoring and Outage Reporting Lumen Maintenance Control Adaptive Lighting Controls Intelligent Transportation System Interaction 2

3 LED SL Program Goals Reduce energy use by 40% - Actual 48%+! Lower maintenance costs (only cleaning during fixture life) Improve Customer Service (no lamp change over fixture life years) Improve operation on Bridges 3

4 41,000 Total Residential LED Streetlights to be Converted 5000 Completed in

5 SCL Lighting Types by Use 84,000 Total Fixtures Pedestrian and Special Lighting 11,705 (14%) Arterial Cobra Head Lighting 31,447 (37%) Pilot Evaluations in 2011 Residential Cobra Head Lighting 40,783 (49%) 5

6 Current SL System Energy Use by Category Pedestrian and Special 14,334,629 kwh (16%) Residential Cobra Head 22,693,382 kwh (25%) Arterial Cobra Heads 52,827,180 kwh (59%) After 6000 LED Streetlights installed Energy Usage decreased 90,000 kwh 6
