SFPUC LED Street Light Wireless Control Pilot Project
Conservation through Innovation
1
Services of the San Francisco Public Utilities Commission
San Francisco Public Utilities Commission (SFPUC)
• Pristine Hetch Hetchy tap water to 2.6 million Bay Area customers
• Award-winning San Francisco Combined Sewer System
• Municipal power from…

Greenhouse gas-free power
• SFO • SF General Hospital • MUNI • Police and fire stations • City-owned street lights

LED Street Light Conversion Project
Ultra-efficient LED fixtures will replace 18,500 City-owned, high-pressure sodium cobra-head style street light fixtures.
6
Improved Lighting
• LED’s produce a neutral white light that’s similar to the natural light of the moon
• Better visibility
7
Less Energy LED’s consume up to 50% less energy than existing lamps
Less Money • Existing lamps burn out
after 4 years • LED fixtures are
maintenance free for 15 to 20 years
8
Coming to a street lamp near you …
… or at least not too far away
• Conversion to LED’s scheduled to begin in one to two years
• Installation will take about 14 months
10
SFPUC Street Light Wireless Control Pilot Project
Identify and test leading LED street light wireless control and communications products.
11
Test Locations
• Washington between Arguello and Presidio • Irving between 6th and 24th • Pine between Davis and Grant, and California
between Sansome and Kearny
12
Wireless Controls for LED Street Lights
• On/off scheduling • Failure detection and data collection • Luminaire grouping • Lumen depreciation adjustment
13
… and there’s more!
• Electric vehicle charging stations data transmission
• Municipal electric meter reading • Street surveillance • Street parking monitoring devices • Traffic monitoring • Traffic signal control • Pollution monitoring • Adaptive lighting 14
Adaptive Street Lighting Management
The practice of adjusting lighting power and output as environmental conditions change.

Benefits of Adaptive Lighting
Adaptive lighting – making the most of LED street lights:
• Reduced light pollution = darker night skies • Reduced light into people’s homes • Increased energy savings • Streets are appropriately lit based upon
pedestrian and vehicular usage
16
Why a Pilot?
• Test technology before purchase • Assess public experience with adaptive lighting
practices • Develop effective adaptive lighting strategies • Determine where, how and when adaptive
lighting is appropriate for City streets
