1 Sensus Lighting Control A Smart Grid Solution for Energy Efficiency and Demand ResponseNational Town Meeting on Demand Response + Smart GridJuly 11, 2013Charlie Nobles – Marketing Manager, Lighting Solutions
2 Sensus - Our Global Vision The leading provider of innovative technology solutions that enable intelligent use and conservation of critical water and energy resources
3 What We Offer Demand Response Smart Outdoor Lighting Smart Grid Communications NetworksSmart MetersAdvanced MetrologyDistribution AutomationDemand ResponseHome Area NetworksSmart Outdoor LightingManaged ServicesSoftwarePeak shaving, event-based load controlTraditionally, DR controls certain loads (HVAC, hot water heaters, pool pumps) to reduce PEAKs or in response to circuit events. LED lighting (smart or passive) reduces OVERALL consumption in Lighting.Energy efficiency and DR
4 The Intersection of DR and Controlled Streetlighting Up to 40% of a city’s energy load can be attributed to streetlightsStreetlights comprise 6% of NYC DOT energy usageAggregated LoadAbility to dispatchOverlap with Load Demand TimesWinter peaking locales can see 30 to 60 minutes of early morning overlapDistribution system based events can have 100% overlap in eveningsNetworked lights have programmed on/off and dimming controlUser interface supports ‘brown-out’ functionsAMI networks can provide both traditional DR control and networked streetlighting control
5 The Street Lighting Market Aggregated LoadAbility to dispatchOverlap with Load Demand Times45M low efficiency street lights in the US to be replacedOnly 3.6% of these have been replaced with ‘passive’ LED lights<1% of existing street lights have any ControlsMany owned/serviced by utilities and billed on flat rate tariffsOver 14M low efficiency parking lot lights
6 The Street Lighting Market Tension Old Tariff structuresTension between Utilities and municipalitiesDropping costs of LED technologiesMove toward “passive” LEDAll Networked Lighting systems are single application network offeringsWho Owns the streetlights?

11 Sensus Lighting Control - Overview Replace inefficient HPS, Metal Halide, or Mercury lamp technology with new FlexNet enabled LED fixtures. Simple field replacement on existing pole arm for street, roadway, and area lighting.Integrated Smart Grid Services PlatformOutage detection and alarm notificationRemote turn-on / turn-off / scheduling over FlexNet networkOn-board ANSI C12.20 metrology for accurate energy measurementCREE XSP lighting fixtureGGL Acorn decorative lighting fixtureCREE LEDway lighting fixtureSLCRemote Control Based on NeedsUtilization of sunrise / sunset tables for turn-on and turn-offReduce energy consumption via programmable dimming controlDemand based delay can help prevent brownouts during peak intervalsCustom groupings of lights can quickly and easily be selected and programmed for emergencies and events, e. g., light enhancement and flashing for increased securityHosted application in the ‘Cloud’GIS mapping and light asset trackingMulti-tenant application interface
12 SLC – Customer Response Deployment underway for replacement of 27,000 street lightings by FallNoted improvement in public park safety and reduction of crime during the PilotEstimated annual savings of $2.7M on total annual cost of street light program – Chattanooga Office of SustainabilityFeatures for Brownout and Peak Demand offsettingUniversity of Alabama field trial and commitment to replace campus lights over 2 yearsKey driver of cost savings coupled with campus safety and lighting control as part of the school safety response program200+ smart electric meters provisioned as well
13 SummaryWith Energy Efficient LED street lighting, with Control, you have the promise of a clear energy efficiency program that has scale, is aggregated, can be dispatched remotely, and can be integrated with other Smart Energy applications on One Network.Energy Efficiency and Dispatched Load ControlThank You!
