Cost and Impact • Operational Costs

– Maintenance • Identifying failures • Replacement: components + labor

– Energy • Mostly unmetered • Estimates: Operating hours x power x energy price

• Energy & Sustainability Impact – KWh/year consumed – CO2 impact: 6.89551×10-4 metric tons CO2 / kWh

Monetizing Energy Savings • Requires new utility tariff(s) • Existing utility infrastructure does not support

accepting metering data • Existing metering standards not (directly) applicable

– ANSI C12.1, 12.20 – Meter accuracy – Data security for billing purposes

• New ANSI C136.50 “revenue grade energy measurement device” standard (specific for lighting) under development

Utility Tariffs

12

Tariff Type Energy Use Determination

Flat Calculated (fixed or variable output) [$/kWh/light per month]

Fixed Energy Metered (utility owned meter) [$/kWh/light + meter charge per month]

Time-of-Use Energy

Metered (utility or customer owned meter) [Variable $/kWh/light per month]

Flat, Variable Output Tariff Example Kilowatt-Hour Use Determination • Lamp type • Size • Ballast • Light control device • Number of lamps or groups of

lamps or lighting components • Hours of operation (burning

Hours), • Dimming schedule together with

the reduced wattage during such dimming hours.

Monitoring • Temporary meter • Sampling program • Periodic testing

kWh/light per month = total annual kilowatt-hours of usage/12

Page 17: Lessons Learned from Outdoor Connected Lighting System ... · Lessons Learned from Outdoor Connected Lighting System Installations . January 12, 2016 Michael Poplawski, Pacific Northwest

Time-of-Use Energy Tariff Example Existing (HPS) • Photo-controlled: 4.8315¢ per kWh

– Dusk to dawn Mon-Sun for all calendar months

• Continuous Burn: 5.5270¢ per kWh – 24 hours a day Mon-Sun for all

calendar months • Part Night

– Dimmed or off for some period each night

– Rate somewhere in between the photo-controlled and continuous burn

New (LED) • Super Off-Peak: 3.3225¢ per kWh

– 11:00 PM–7:00 AM, Mon-Sun for all calendar months

• Off-Peak: 8.1538¢ per kWh – Weekends, holidays and any day in

Oct–May: 7:00 AM–11:00 PM – June–Sept (Mon–Fri): 7:00 AM–2:00

PM & 7:00 PM– 11:00 PM • On-Peak: 9.4595¢ per kWh

– 2:00 PM–7:00 PM, Mon–Fri, June–Sept (Summer)

– Excludes Independence Day and Labor Day

demarcation? • Electrical system in

compliance? – NESC vs. NEC

System Configuration

Installation Start-up Commissioning

Devices have basic necessities for operating as

intended

• Luminaire integration • Input voltage • Wiring configuration • Sensor integration • Ancillary devices

Devices are operating as intended, all system

functions and capabilities are available to the user

• Lighting control protocol • Electromagnetic

immunity (EMI) • Network architecture • Wireless spectrum • Backhaul availability • Security

System functions and capabilities are configured according to user desires

• Location • Grouping • Scheduling • Real-time monitoring • Sensor algorithms • Adaptive Lighting • Command Prioritization

– 3-prong receptacle (ANSI C136.10) – 5-7 prong receptacle (ANSI C136.41)

• External to luminaire, variable output – 3-prong receptacle (ANSI C136.10) + wired solution – 3-prong receptacle (ANSI C136.10) + power-line carrier (PLC)

solution – 3-prong receptacle (ANSI C136.10) + wireless solution – 5-7 prong receptacle (ANSI C136.41)

• Internal to luminaire – Installation, responsibility – LED driver interaction (heat, unintentional radiation) – Antenna

• Integral to luminaire (i.e. internal to ballast/driver)

Lighting Control Protocol Options

• 0-10V – One-way analog communication with driver/ballast – Can not set power or light level

• DALI – Two-way digital communication with driver/ballast – Can set light level – Can (theoretically) extract luminaire, driver/ballast

characteristics (e.g. make/model, power profile) – Can report driver/ballast characteristics (e.g.

temperature) • Integral to luminaire driver/ballast

Location Commissioning Options • No capability • Controller location is

assigned from an existing database

• Controller location is captured using a field commissioning device (with GPS)

• Controller captures its own location (via integral GPS)
