LED Utility Outdoor Lighting
Progress Energy is an investor owned utility that has one million outdoor lights in service throughout portions of NC, SC and Florida. The City of Raleigh, NC was the first LED City for CREE and currently has over 63 LED test installations. The city’s strong desire for LED street lighting encouraged Progress Energy Carolinas to develop the first line item bundled lease utility rate for LED street and area lights in the US. Bob Henderson, LC, CLEP led this introduction of LEDs at Progress Energy. The challenge was to develop options to deal with the higher cost of LED fixtures that would earn the allowed return for the utility without having a severe impact on municipal street light budgets. In short a win-win was needed.
Bob will describe some of the barriers and steps taken to break these barriers to introduce and gain utility commission approval of a new rate and associated LED products. He will also discuss other associated lighting decisions along the way. Some of the program topics will include the new rate format and change-out policy, CCT preference and environmental issues, vendor questions about LED luminaires, mA ratings and more.
The following topics will be covered during Bob’s presentation:
- LED basics and components
