Street Light Rate Schedules_________________________________________________________________________________________________________________________________________________________
• Issues– Street Lights are typically unmetered– Rate based on type of lamp, calculated energy use– No “standard” products– Lengthy regulatory process– What about controlled streetlights?

Street Light Rate Schedules_________________________________________________________________________________________________________________________________________________________
• Proposed Solutions– Develop “wattage categories”
– Validate energy consumption based on IESNA LM-79 test– Adjust controlled streetlights based on confirmed operating
