1 Remote Monitoring & Adaptive Lighting Control Systems LED Street Lighting Workshop - Boston August 3-4, 2012 Michael Poplawski, Senior Lighting Engineer, PNNL

2 LED street lights can save you energy and money Ideally with improved lighting performance Sometimes with, sometimes without reduced illuminance Not a simple 1-for-1 replacement; education and homework required Remote monitoring & adaptive lighting control systems can save additional energy and money Not as simple as installing a new PE or checking an option on street light order; education and homework required 1

3 Value propositions Reduce recurring maintenance costs Immediate feedback on outages, dayburners Reduce energy costs Dayburners Dimming Extend luminaire lifetime Lower power Lower time-of-use 2

4 Value propositions Lumen maintenance Fixed light output with increasing power vs. decreasing light output with fixed power Diagnostic maintenance Based on luminaire feedback Respond to transient events Public safety concerns, issues Police, fire, maintenance activity Special events 3

5 Big questions What is your (baseline) cost of maintaining (or not maintaining) your street lighting system? Will you dim? Why or why not? According to what lighting guidelines? Will you install controls coincident with (LED) street light installations? 4

6 User internal environment What rules, requirements, options do you have? Capital expense payback, recurring expense management Financing options Internal or external service, management of networks, hardware, software 5

7 User internal environment What infrastructure, capabilities do you have? Asset management system Communication networks Capability: fiber optic, twisted pair Density (traffic signal) IT department Servers Security 6

8 Quantifying value propositions How will you monetize savings? Maintenance Reduce, eliminate dayburners Dimming What else matters to you? Outage processing cycle time Extended luminaire lifetime, lumen maintenance, diagnostic maintenance Transient event response 7

9 Utility partnership Can you monetize energy consumption savings from dimming? Metered lighting circuits? Fixed control/dimming schedule Variable control/dimming schedule with metering Metering accuracy Energy data reporting format 8

10 Utility partnership Streetlight tariffs PGE Network Controlled Dimmable Streetlight Pilot Program ess/customerservice/startstop/streetoutdoorlighti ng/streetlight_pilot_faq.pdf 9

11 Reducing light output IES RP-8 Municipal Guidelines ADAPTIVE LIGHTING: LUMINANCE METHOD CRITERIA Selected Street Classification Selected Pedestrian Classification Average Luminance (cd/m 2 ) Adapted Luminance (cd/m 2 ) Major High Medium Low Collector High Medium Low Minor High Medium Low portfiles/green vision/public_streetlight_design_guide.pdf 10

12 Rollout When and how will you install controls? Together with luminaire installs Independent of, subsequent to luminaire installs One or multiple phases (facilitated by standards) Will you install control-ready luminaires? What does control-ready mean to you? Dimmable driver Installation tools, time 11

13 Installation of control hardware Internal to luminaire External to luminaire NEMA 3-pin (power) + other dimming NEMA 5-pin (power + dimming) ANSI C Controller plus antenna Field vs. remote installation Energized or off Cost efficiency 12

14 ANSI C proposal 13

15 Deployment What does the street light inventory that you want to control look like? Voltage Density, topography Interference sources How will you commission the system? Who, when, how 14

16 MSSLC tools Model specifications For LED Roadway Luminaires For Remote Monitoring and Adaptive Control of LED Roadway Luminaires Retrofit financial analysis tool Recommended practices Dimming characterization 15

17 MSSLC Model Specification for Remote Monitoring and Adaptive Control of LED Roadway Luminaires 1) User Interface 2) System Interoperability 3) Network Performance 4) Inventory Management 5) Power, Energy Measurement 6) Remote Monitoring 7) Adaptive Control 8) Security 9) Installation 10) Commissioning 11) Maintenance Inventory Management System Backhaul Communication System Controller-Controller, Controller-Gateway Communication Standard Roadway Luminaires

18 Closing thoughts If you are installing LED luminaires, start thinking about controls now ( control-ready ) Learning opportunities Municipal demonstration projects (many) Municipal installations (Los Angeles, Portland, Glendale, San Jose, Austin ) 17

19 Closing thoughts MSSLC is investigating and developing tools Model Specification (coming soon) Technical Committee GATEWAY demonstration projects (next FY) Standards are coming ANSI C TALQ ( 18
