maintenance representing the highest cost for LED as well as UPS as well; cost of each cobra head fixture at approximately $90, but the LED infrastructure cost currently about $300 until manufactures can reduce that cost based on economy of scale; replacement of bulbs versus the entire board and which was found the most efficient based on their life expectancy (23 years for a board); components (e.g. starter, ballast, bulb, other components) and their inability to be recycled at this time, but not identified as hazardous waste as they didn't contain mercury vapor, which is no longer usable in MN. Additional discussion included life expectancy of LED bulbs at approximately 15- 25 years; and potential reduction in operational and maintenance costs as LED lighting moves to the forefront, estimated at approximately 50%. Mr. Bieging noted that use of LED lighting for decorative will not be as effective, nor save money, due to their design and limited lighting capabilities and levels, since LED lights are more direct than conventional UPS fixtures with lighting reflected and refracted inside the fixtures and distribution patterns; as well as the public perception of LED lighting as more measured with the whiter light and allowing use of lower wattages as technologies improve. Ms. Jurek advised that it was Xcel's intent to conserve energy and pass that savings on to its customer base, as well as reducing overall emissions. Further discussion included off-peak power considerations and controls; directional lighting where needed through use of LED lights directed on streets and sidewalks for safety versus into customer's yards (e.g. keyhole to keyhole lighting); relative ease in retrofitting existing cobra head light standards with LED technology; and reluctance of Xcel to consider dimming street lights when needed less due to litigation issues, as well as other considerations. In conclusion, Mr. Bieging advised that new technologies were driving the future of outdoor lighting and the entire industry over the next 10-15 years, with Xcel hoping to be in a position of leadership with a strategic plan for replacing and updating outdoor street lighting systems. Mr. Bieging noted that there was a considerable amount of pressure to move this LED street light program forward in the Midwest, advising that this may prompt an earlier resolution. Mr. Bieging advised that studies for LED lighting in eastern and western states were more advance, primarily due to higher rate structures than currently realized in Midwestern states. Chair Vanderwall and Commissioners thanked Mr. Bieging and Ms. Jurek for their informative presentation. 6. Uniform Commission Code Proposal As previously requested by the PWETC, Mr. Schwartz provided a DRAFT copy of the proposed ordinance (Attachment A) being developed by staff to provide a Page 4 of 17
