Streetlight Program Progress
1980: Installs LPS & HPS 2008: Revises Streetlight Policy 2008: SJ demo “smart” LED lamps 2009: SJ trailblazer on “smart” streetlights
Pilot project converting lower wattage Pilot project converting higher wattage
2010: Streetlight Demonstration Project 2010: SJ continues to influence LED lighting

Driving Factors
Reduce O&M costs 13,000 lights replaced/repaired per year 3 year cumulative general fund deficit > $100 m Spending $4 m/year on energy 900 streetlights shut off in 2008
Improve quality of lighting
Directional lights Advance San José Green Vision
Protect night sky for Lick Observatory

Strategy General
Technology Dimming White light factor Metering
Conversion Plan Get most bang for the buck Citywide exposure to white light
Challenges Observatory concerns Funding Regulations – meters and tariff

Network Control System Communication and control system
Programmable and remotely controlled Powerline/Wireless communication system Web based access GPS positioning Monitoring and reporting application
Challenge Finding system with minimal on-going fees Maximize use of existing communication
infrastructure

Metering
Benefits Credit for actual energy consumed

Metering
Current Challenges Acceptable level of accuracy
Currently streetlights un-metered: no data High accuracy standard for residential and commercial Cost prohibitive for streetlights to meet this standard
Need to find the “sweet spot”

Metering
Future Challenges Regulatory and Administrative
Tariff change to reflect individualized meter Security Meter ownership Level of reports/data

Municipal Consortium
Participation Advance LED lighting and network controls Remote Monitoring and Controls Workgroup
Information Repository Forum to share information
Tested and tried “best practices” Develop consistency in standards
![Page 15: San Jose: LED Street Lighting and Controls - Energyapps1.eere.energy.gov/buildings/publications/pdfs/ssl/olay_street...San Jose: LED Street Lighting and Controls Author: amy.olay Subject:](https://reader031.fdocuments.in/reader031/viewer/2022030422/5aaa327f7f8b9a77188dd03a/html5/thumbnails/15.jpg)
What’s Next? Community meetings to share outcome of
Streetlight Demonstration – Summer 2010 Streetlighting Master Plan – Fall 2010
Adaptive Lighting Design Guide
Work with PG&E and CPUC to allow local agencies to allow streetlight metering
Implement funded projects Continue to seek grant funding Explore various financing options
