Included - Village of Huntley

MEMORANDUM
B. The Village requested CBBEL estimate costs associated with the retrofit of the existing
lighting system along the segment of Kreutzer Road installed as part of the Lions Chase
residential subdivision. CBBEL counted 27 existing streetlights along the existing segment
of Kreutzer Road.
27 fixtures x $1,300/each installed LED fixture retrofit kit = $35,100
3 controllers to be modified with meters: 3 x $1,500 per controller
(assumed) = $ 4,500
Total estimated retrofit construction cost = $39,600
ComEd one time rebate program savings (if available): 27 luminaires x
$15 per fixture = ($ 405)
DOE one time incentive program savings (if available): 27 luminaires x
$15 per fixture = ($ 405)
Total retrofit cost approximately = $39,000
C. CBBEL recommends the Village consider the following issues related to the use of LED
technology and to the retrofit of existing HPS streetlights to LED systems.
The current rate of $0.03 per kW-hr that the Village pays for electrical service from
Commonwealth Edison on the Rate 25 contracts is considered to be at the low end of
rates CBBEL typically sees with our other municipal clients.
The overall age of the majority of the Village’s street lighting systems is plus or minus 10
years. CBBEL approximated the Village’s average age of the street network to be 10
years in our 2011 pavement evaluation report. Typical luminaire life should be
considered to be 30+ years.
The pace in which LED technology is evolving may mean current LED retrofit kits may
be obsolete in the near future when replacement parts may be required for knock downs
and miscellaneous physical damage.
Following the retrofit of a Village street lighting system, the Village may have to stock
additional LED retrofit kits in advance of possible maintenance repairs being identified.
Having the material on hand would provide the ability to make timely repairs to the
system to avoid long delays in obtaining replacement parts as LED parts are not stocked
by local electrical supply houses as HPS and metal halide lamps are typically stocked.
SOLAR POWERED STREET LIGHTING
CBBEL is continuing to research and explore the options related to solar powered street lighting
equipment. Please find attached a brochure CBBEL was able to obtain from a manufacture of a
solar / wind powered lighting equipment.
