1 Anchorage Municipal Light & Power LED Streetlight Initiative Growing Sustainable Communities Conference 3 October 2017 Gary A. Agron Division Manager, Engineering Municipal Light & Power Mark Wilbur Senior Solutions Architect General Electric

2 Mission Municipal Light & Power converts over 3900 HPS Streetlights in its service area to networked LED fixtures NLT 31 Dec Vision Savings, Safety, Sustainable

3 Definition sus tain a ble /səˈstānəb(ə)l/ adjective 1. able to be maintained at a certain rate or level. "sustainable fusion reactions 2. able to be upheld or defended. "sustainable definitions of good educational practice"

4 ML&P Street & Area Lighting One of eleven street lighting departments in Anchorage 110 miles of streets are illuminated ~4,000 cobra head streetlights in four predominant wattages

5 The Value 50 % Energy Savings Cars (approx.) 1,800 cars off the road ~4,000 LED Streetlights 2000 Metric Tons CO2 Reduction $350,000/year Savings Homes (approx.) Energy for 1,900 homes Reduced Power Consumption/Costs ($350k/yr) Reduced O&M Costs ($50k/yr) Improved lighting quality Greater metering capability Improved Asset Management Improved inter-departmental cooperation Control Output with more precise dimming schedules, notably for middle-ofnight operation in low-traffic areas: save energy Control Metering with per-pole utility-grade metering, only pay for what s used: save money Control Maintenance with quicker, more efficient upkeep. Attain better maintenance scheduling and response to outages: save manpower

6 Bundling Advantage

7 Adaptive Strategies for Safety and Energy Efficiency* 120% 100% 80% 60% Parks & Rec 40% 20% Parking Lots Street Intersections Streets & Roadways 0% 30 minutes before Sunset Sunset - Midnight Midnight - 3 a.m. 3 a.m. - Sunrise 30 minutes after sunrise * Set to astronomical clock in Anchorage

8 ML&P LED Streetlight Initiative Convert ~4,000 streetlights to LED Install Wireless Control System Timeline 2017 Field Installation by ML&P Crews Total Cost Est $3.4 million Program payoff 10-years Launched May 2016 (20 lights in 2016; remaining in 2017) RFP initiated

9 Energy Use reduction Goal: >40% Desired Effects Measurement begins at Full Operating Capability (FOC) O&M Reduction Goal: >95% after FOC Measurement begins at FOC Customer Acceptance Goal: Complaints < 10 per month Illuminates per spec Measurement begins at FOC Project Scope, Schedule, Budget Goals: no scope creep; installation completed NLT 31 Dec 2017; under $3.4M

12 Initiative Geographic Area LED Conversion of ~4,000 streetlights in the ML&P Area of Operations

13 The Luminaire ~4000 LED Streetlights Minimize distraction glare Zero up-light (IDA Compliant*) Cold-weather tested 15-year lifetime 10-year warranty Quick Connect ANSI C (Control Capable) $250 $500/LED (Size dependent) LED light bulbs provide a huge opportunity for energy savings and make a substantial contribution to sustainable development.

14 The Network Experienced Enterprises: Phillips: CityTouch (Los Angeles, San Francisco) GE*: LightGrid (San Diego, Jacksonville, NYC, Chicago, Calgary, Oakland) Lumewave: Echelon (Cambridge, Bellingham) Telensa: PLANet (UK) *Current ML&P Standard LED

15 Status Gateways & Modems: Seven sets deployed and operational Two areas uncovered; plan TBD LED Streetlights and Nodes Delivery by Area synch d Planned vs Actual installation rate One area remaining Disconnects and Stale Nodes resolution Customer education FAQs on ML&P Website Expanding Parks & Recreation Bike & Ski Trails Municipal Transit Bus Depots and Stops Pilot in development with adjacent utility Sep

16 Before After Pine Street, Mountain View Subdivision, Anchorage Alaska. Taken February, 2017, by Wayne Johnson, ML&P

17 Public Reaction Overall very positive Resident Concerns too bright I can t see the moose in my yard lights up my yard are you watching me? lights are shining in my living room you re violating the AMA directive Concerns dissipated as late-spring came around

18 Improved Lighting Reduced Energy Usage Less Maintenance Public Outreach Installation Progress Map Website: /Projects-Construction/LED- Street-Light-Conversion LED Streetlight Conversion Initiative

19 What we re working on Governance of controlled lighting Dimming Emergency Requests Light Removals IDA concerns Tariff rates Expandability IoT Applications on Streetlight Network Small Cell

20 Challenges Gateways: 3G/4G Network AT&T or Vz? Shipping to Alaska Tariff and the Regulatory Commission Municipal Design Criteria and International Dark Skies Meter Shop Metering accuracy verification & Birth Certificates Billing 15 minute reports compiled for a bill too much data getting the right files Installation High vs Low Voltage Right of Ways Parked Cars and Snow Berms LightGrid: stale and disconnected lights (reported)

21 ML&P LightGrid

22 What we re learning Energy reduction: 51% (2016 vs 2017) Maintenance Call Outs for lights: < 6 since installation began Customer Complaints ~ 12 since installation began Installation faster than planned Distribution can t get around Asset Management and visibility enhanced Others want to join our LightGrid Network Controlled LED Streetlights push to smart lighting technology The benefits to the community are clear, affordable and sustainable.
