Introduction
• The City of Edmonton operated 98,000 HID streetlights.
• These consumed nearly 73,800 MWh of energy per year.
• Annual maintenance costs were approximately $9.4 Million.
• The City needed to reduce maintenance and energy costs while advancing Edmonton’s conservation culture.
• Reduced light pollution, improved safety and leading with innovation were mandated.

A New Technology…
• Life up to 100,000 hours.
• Reduced consumption up to 70%.
• Adaptable controls.
• Flat lens design to reduce light pollution.
• Improved efficiency in colder temperatures.
• In 2006 the City of Edmonton completed the conversion of 17,000 traffic lights to LED.
• The application was highly successful.
• The City was ready to further test this new technology…
THE POTENTIAL THE FIRST STEP

Senior Street Light Engineer City](https://reader035.vdocuments.net/reader035/viewer/2022080506/5f79bd10f9c47c7ab45dc86b/html5/thumbnails/4.jpg)
The Move To Study
• In 2009 the application of LED for street lighting was still unproven.
The Question
• EPCOR Technologies commissioned to evaluate LED street lighting feasibility.
The Contractor • Five manufacturers
are chosen to pilot their roadway capable LED luminaire in various neighborhoods.
The Pilot
![Page 5: City of Edmonton Street Lighting Initiatives · A City of Edmonton and EPCOR Technologies Pilot Project in LED Implementation Vlado Cicovski P.Eng. Senior Street Light Engineer City](https://reader035.vdocuments.net/reader035/viewer/2022080506/5f79bd10f9c47c7ab45dc86b/html5/thumbnails/5.jpg)
Methodology
• Pre-existing pole spacing was maintained.
• Installed five of each manufacturer’s luminaire side by side.
• Used a 100W HPS Lumec Helios as the reference point.
• Pilot areas covered a minimum of one residential block.
• Tested on ease of installation, illumination performance, energy consumption and cost.
![Page 6: City of Edmonton Street Lighting Initiatives · A City of Edmonton and EPCOR Technologies Pilot Project in LED Implementation Vlado Cicovski P.Eng. Senior Street Light Engineer City](https://reader035.vdocuments.net/reader035/viewer/2022080506/5f79bd10f9c47c7ab45dc86b/html5/thumbnails/6.jpg)
Pilot Study
• Lighting simulations were modeled for efficacy using AGi32 software.
• Modeled with both standard and manufacturers level of depreciation.
• The two simulations provided similar results.
• Top ranked luminaire produced 67% greater luminance.
Lighting Performance

Pilot Study
INSTALL
• Looked at leveling, terminals, overhead wiring access, construction and handling.
• Of five tested only one proved difficult.
ENERGY
• Bottom ranked consumed 60% more energy.
COST
• Highest payback at 25 years.
• Lowest payback at 12 years.

Pilot Study
• 10 year all inclusive material warranty
• Industry standard 3rd party testing reports
• Surge protection requirements of 10kV
• LLF for ambient nighttime annual temp of 2.6°C
Specifications were built to remove as much risk as possible
from the customer.
Requirements included…
Luminaires meeting these specifications were pre-qualified

The City of Edmonton’s Environmental
Strategic Plan
The Way We Green
• It sets out principles, goals, objectives and strategic actions and
approaches for Edmonton to live in balance with nature.
• Some of the goals:
– Edmonton’s communities are full of nature — a place where in
the course of everyday life, residents experience a strong
connection with nature.
– Edmonton’s sources and uses of energy are sustainable.

Strategic Plan
Edmonton’s Environmental Management System
• This policy establishes the ISO 14001, the international standard, as
the benchmark for a corporate Environmental Management System
(EMS). Standard Environmental Management System practices
across the City will address environmental regulatory compliance,
pollution prevention and continual improvement.

Neighbourhood Renewal
• The Neighbourhood Renewal program is part of the Building Great
Neighbourhoods initiative which outlines a cost effective, long-term
plan to address the needs of Edmonton’s neighbourhoods. The
program involves the renewal and rebuilding of roads, sidewalks and
streetlights in existing neighbourhoods and collector roadways
balancing the rebuild need in some neighbourhoods with a
preventative maintenance approach in others.

Design Considerations
• Maintain current lighting levels.
• Address over and under lit areas.
• Re-design for high night time collision locations.
• Identify pole and luminaire style requirements for heritage neighborhoods.
For
Neighborhoods
• Host open houses for Q&A prior to install.
• Notify residents of install date.
• Anticipate some initial discomfort with “White” light.

Implementation
KICK-OFF
• Understood as-built legends up front.
• Surveyed for conformity in pole base size.
• Surveyed for pole and base condition.
INSTALL
• Local staging facilities.
• Pre-wiring in-house.
• Crews were able to work in winter downtime due to lack of underground construction.

Lessons Learned
PRODUCT
• Know your asset base - non-standard bases require modifications to new pole flange or install of a new base.
• Older neighborhoods saw more modifications of pole bases.
• Ensure new upgrades meet new Canadian Electrical Code.
• LED color temperature allowed a lower wattage than anticipated still meeting historical lighting levels.

Lessons Learned
INSTALL
• Stage locally and group retrofit by neighborhood when possible.
• Redesign light distribution type for poles close to corner lots.
• Survey base condition and size in older neighborhoods.
• Record out of box failures for warranty coverage.
• Define failure with the manufacturer.
• Ensure retrofits are logged closely in order to calculate immediate energy savings.
