What is it?

• A small control unit that can be installed inside
  the streetlight fixture at an estimated cost of
  35, plus labor (approximately 6).

3
Why should BPA and owners of streetlights be
interested?

• Significant energy savings can be accomplished
  with a moderate investment
• This streetlight unit test may qualify for
  Research Development Demonstration under CRD
• Reduced maintenance costs in labor and material
  are substantial

4
What does each individual control unit do?

• Turns lights on and off at preset times (most of
  the savings here)
• Eliminates day-burning streetlights using a
  cadmium sulfide cell day/night sensor
• Cuts power to the lamp when lamp cycling
  (failure) is detected, thus eliminating damage to
  ballasts and eliminating Radio Frequency
  Interference (RFI)
• Trouble light alerts maintenance personnel of a
  malfunction, during the daytime
• The real-time clock (daylight savings, leap year)
  is backed up by a 72 hour supercapacitor
• Hand-held remote control used to set time and
  timer
• Manufacturer provides a ten-year warrantee

savings are two-fold

• Energy savings
• The Smart Pack can turn its light off during
  hours of the night when less or no light is
  needed (Remote-control programming.)
• Labor and material cost savings
• Lamp cycling damage to ballast and igniter is
  eliminated
• Eliminates Radio Frequency Interference (RFI)
• Lamp lifecycle increased
• L.E.D. makes a faulty lamp easy to spot in the
  day time
• Unit installed inside the light fixture (weather
  protected)

6
Power Savings because less electricity is used
7
Investment Savings because no need to replace
photo cells
8
Investment Savings because fewer lamps to
replace
9
Labor Savings because fewer lamps need
replacement
10
Annual costs savings based on turning lights
off and no cycling photo control problems

The plan 500 streetlight test

• Ask one to three utilities to participate in a
  500 light fixture test
• Full service customers are the most desirable
  candidates for participation in the test
• Any savings can count towards the requested 10
  load reduction
• BPA pays for the control unit installation cost
  is the responsibility of the participating
  utilities
