POSITION Lighting is an ideal electric end use
for load management

• Available in virtually every building
• Easy to control
• Easy to measure the results
• The load reduced is repeatable
• Can reduce the amount of lighting rather than
  turn it off, thereby preserving productivity

HOW IS LIGHTING CONTROLED TODAY

• Manual control turn off the light switch
• Through the buildings energy management system
  turn off the lights
• Issues
• People arent as productive in the dark
• Cost of Maintenance Personnel to manually turn on
  off lights

CAN CUSTOMERS BENEFIT FROM LOAD MANAGEMENT?

• Benefits received from Utilities or System
  Operators are less than adequate to recover costs
  of current lighting technologies
• Full dimming ballasts are costly
• Loss of productivity, when turning off the lights
  is high
• Simple paybacks exceed 10 years

SOLUTION Develop a cost effective ballast
controller that will

• Dim lights / reduce demand for power
• Retain worker productivity
• Not effect lamp life
• Control from central location, internal or
  external to building
• Pay for itself within 3 years

With funding fromU. S. Dept. of Energy
California Energy Commission Connecticut Light
PowerNew York State Energy Research
Development Authority

• Lighting Research Center has developed a load
  shed ballast

• Instant start ballast platform Add circuitry to
  reduce current to lamps by fixed amount

Load-shed Ballast
Dim Lights

• Receiver for dimming signal
• Incremental cost of no more than 8

• Dimming occurs over 10 seconds

CONTROLLER
RF pager/radio signal
Receiver Signal to Dim Ballasts
Transmitter To Ballast
Power Line Carrier to Ballast
Internet
Hard wired to EMS
Push Button

• Interchangeable circuits for how signal is
  received
• Minimum data transferred to ballast (on/off)
• PLC allows for no additional wiring

• Estimated cost 1 per ballast

PAYBACK TO CUSTOMER

• Dependant on location, utility demand charges or
  System Operator incentives
• Cost of 9 per ballast
• Benefit Simple Payback
• New York City 6/yr. 1.5 yrs.
• Ohio 4/yr. 2.25 yrs.
• Chicago 3.50/yr. 2.6 yrs.
• Georgia 2.80/yr. 3.2 yrs.
• Connecticut 3/yr. 3.0 yrs.
• New Jersey 2.80/yr. 3.2 yrs.
• California 3.50/yr. 2.6 yrs.

WHERE IS IT?

• Ballast is developed Discussions with large mfr.
  underway
• Controller being tested Manufacturer interested
• Full scale demonstration in NYC in 2004, Utility
  to ballast
• Seeking funding for 3 additional demonstration
  sites
• Commercialization late 2004
