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
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

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
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)
ML&P LightGrid
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.
