LED Street Lighting Project
RECOMMENDATION
THAT: Council authorizes staff to negotiate with Entegrus Powerlines Inc. as project manager
to further develop a Request for Proposals for the implementation of the LED Street Lighting
Project, to be considered as part of the 2015 budget.
BACKGROUND
In 2014, the Municipality of Strathroy-Caradoc developed an Energy Consumption & Demand
Management Plan as part of its compliance with the Green Energy Act legislation. The plan
included a target of 5% reduction in energy consumption by 2020. In order to achieve this goal,
Council and staff have actively pursued opportunities to realize greater efficiencies within
operations to decrease energy demand.
Over the last several months, members of municipal staff have investigated the costs
associated with the retrofit of all existing street light fixtures with energy efficient Light Emitting
Diode (LED) technology. The Municipality of Strathroy-Caradoc currently owns and operates
an inventory of 1,992 street lights in the community of Strathroy, and 260 in the community of
Mount Brydges through Local Distribution Company (LDC) Entegrus Powerlines Inc. StrathroyCaradoc also owns and operates 90 additional street lights in the rural areas of the
municipality, which fall within LDC Hydro One territory.
CONSULTATION
Working with Entegrus, a complete audit of existing street lighting within Strathroy and Mount
Brydges was completed to assess potential savings through conversion to LED fixtures,
resulting in a conversion proposal that estimates a reduction of over 196 kW of connected
load, or a reduction of between 53.6% and 57.1% in energy consumption (taking into account
only the 2,252 fixtures located within Entegrus territory). See attached Payback Calculation for
more information. The fixtures located in Hydro One territory must also be included in any LED
upgrade proposal moving forward to ensure that a complete replacement program is achieved,
adding further reduction in overall energy consumption.
As part of their review, Entegrus has provided detailed specifications for the appropriate LED
lighting, with site-specific requirements based on factors such as desired luminosity, road
surface, pole placement, etc. See attached Material Specification for Roadway Luminaires for
1
more information.
FINANCIAL IMPLICATIONS
The proposal developed by Entegrus provided an outline of financial implications for the
fixtures located within Entegrus territory only. Before proceeding with the project, a complete
audit of fixtures for Hydro One territory must be added to the scope of work, and special areas
where specialized lighting is required (ie. decorative light standards in downtown Strathroy)
must also be completed.
Examining only the 2,252 fixtures in Entegrus territory, the proposal outlines a projected capital
cost for fixture replacement at $648,130, including a 10% Project Management Fee. The
proposal also estimates approximately $145,984.87 in annual energy savings, and a
$35,190.60 reduction in maintenance costs due to the longevity of LED roadside luminaires.
Based on these calculations, it is estimated that the cost of retrofitting the complete inventory
of street lighting in Entegrus territory would see a return on investment after only 3.5 years
(see attached Payback Calculation for more detail).
COMMENTS & NEXT STEPS
Based on the review above, it is recommended that the municipality engage Entegrus
Powerlines Inc. to further define the needs of the municipality in terms of street lighting in
Hydro One territory and areas requiring specialized lighting requirements. Once the
appropriate data is gathered, a project management agreement will be established with
Entegrus for Council review and approval. With a satisfactory agreement in place for project
management, Entegrus will proceed with a public Request for Proposals process in
compliance with the municipal Purchasing & Procurement Policy in order to determine an LED
fixture supplier and installation contractor.
Moving forward with the support of the Local Distribution Company will provide the expertise
and experience necessary to ensure that the municipality achieves the best possible outcome.
Entegrus brings to the project a vested interest in the long term viability of the system, and the
ability to assist the municipality in acquiring the maximum rebate funding through available
Ontario Power Authority incentives. With this in mind, the proposed 10% project management
fee is a responsible investment and reasonable for a project of this scope.
With Council approval to move forward, the LED Street Lighting Project would proceed in the
spring of 2015, and be accomplished over an 18 month period, with full completion achieved in
2016.
Staff will be available to answer questions regarding the report.

It may be the intention of Entegrus to dim luminaires during night-time operating hours,
therefore it is desirable, but not mandatory, to have units with an optional dimming capability
should the town decide to include a dimming control system. Dimming control should either
be through a pre-programmed internal switching device, by a wireless control system, or a
combination of both. As an option, the manufacturer shall state its product's capability
for dimming, requirements to make its luminaire "dim-ready", what accessories would be
needed in the base luminaire unit, and what the capital cost adder would be.
4) Quality Assurance
a)
Before bulk purchase, Entegrus may request for inspection one or more standard- production-model
luminaire samples identical (including LED package) to product proposed to be installed. Owner
may request independent testing of sample luminaires to verify luminaire performance and
compliance with the specifications.
b) After in stallation, Entegrus may perform field measurements and/or send luminaires to an
independent laboratory for testing to confirm photometric performance.
5} Pack~gj[lg & Shipping
a) The luminaire shall be shipped as a single self-contained unit in its own boxed container. The
luminaire shall be fully assembled at the factory and not require any on site assembly. Each un it
shall include installation and ope rating instructions.
6}
Warranty
a) The manufacturer shall warrant the replacement of any component due to manufacturing
defect or failure of that component (including LED array and LED driver) for a period of 10
years from date of delivery. Alternatively, the manufacture may opt to repl ace the
entire luminaire at no cost to Entegrus.
PART II- LUMINAIRE PHOTOMETRIC AND ENERGY PERFORMANCE EVALUATION
A; Design Standards
1) It is of primary importance to Entegrus that LED roadway lighting equ ipment conforming to this
specification achieves significant energy usage reduction over the currently used High Pressure Sodium
roadway lighting systems while meeting or exceeding IESNA RP-8-14 Table 3 photometric performance for
luminance level, uniformity and glare control.
It is the intent of this specification to have Vendors, as part of the prequalification process, perform
lighting installation photometric and energy usage calculations for typical municipal roadways using
their selected product. Entegrus will evaluate to what extent the product can deliver the required energy
and lighting performance required for its roadways. Table A summarizes these typical example
roadways. Typical Sections 1 - 7 in Table 2 depict 7 typical municipal roadway geometries to be used
for evaluation purposes by the Vendor. The "typical" calculations will be used to evaluate the product's
suitability to light the roadways under the following three construction scenarios:
2)
a)
New Construction - Independent stand-alone street lighting system with optimized pole spacings and
luminaire selection . Fixed mounting heights and mast arm lengths shall be observed.
b)
New Construction- New street lighting luminaires installed onto new electric utility distribution
poles. Fixed mounting heights, and pole spacings shall be observed.
c)
Retrofit Programs- New street lighting luminaires for retrofit onto existing poles and mast arms . Fixed
mounting heights, pole spacings, and mast arm lengths shall be observed.
Design Restrictions
a)
In reference to the typica l roadway Figures 1- 7, it is not intended to deviate from the indicated
mou nting heights of 6.7 meters for cobra head style lum inaires due to a reluctance to change
from current construction and equipment standards. It is also not possible to change the
location of the poles as indicated relative to the edge of pavement as this is mandated by Entegrus to
avoid underground and surface utility location conflicts.
3)
Energy Usage
a)
4)
Vendors shall calculate the total energy input for a one kilometer section of straight street for
streets depicted in Typical Sections 1- 7
Light Loss Factors
a)
It is the responsibility of each manufacturer to provide a calculation of Lamp Lumen Depreciation (LLD)
for each photometric file used. LLD shall be based on actual lumen depreciation values reached at
87,600 hours at 25° C luminaire ambient and as proven by LM-80 back-up information and as
calculated using the procedures outlined in TM-21-11 as required under section C.4.
b)
For this evaluation, the LDD attributable to accumulation of ambient airborne particulates onto
the luminaire's exposed light emitting surfaces shall be 0.90. The LOO figure of 0.90 was derived
from Figure 2 in IESNA DG-4-03 corresponding to a 5 year exposure time and the "very clean" dirt
condition curve. It is Entegrus's intent to continue to clean the exterior of the light emitting shield
I refractors once every 5 years. Airborne particulate levels (PM 2.5) as recorded in 2009 by the
Ontario Ministry of the Environment did not exceed 150 micro grams per cubic meter in the
Southwestern Ontario area.
5) Installation Life
a)
It is Entegrus' s expectation that the in-service life of a typical LED luminaire installation will be 20 years.
This corresponds to an 87,600 hour on-time operating life based on 4380 hours of operation
annually.
6) Lighting Performance
a)
Lighting levels, uniformity ratios, and veiling luminance ratios are from the IESNA RP-8-14
Recommended Practice Table 3 and are required to be met for roadways depicted in Typical Sections 1
- 9 . These lighting requirements are indicated in Table 1.
b) The indicated lighting levels in Table 1 are those to be present at the end ofthe 20-year luminaire
useful life. They shall observe the 25 deg. C ambient operating temperature, the manufacturer's
light engine LLD and the 0.90 LDD attributable to accumulation of operating ambient particulates.
(Refer to Item 4 above)
c)
Photometric calculations shall recognize only photopic lumens and will not incorporate any
mesopic multiplier factor. Calculations shall observe current IESNA calculation and
measurement methods.
