					LIGHTING AND LOAD MANAGEMENT

Peter Morante, Director of Energy Programs, Lighting Research Center, Troy, NY

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
Lighting Research Center

HOW IS LIGHTING CONTROLED TODAY






Manual control – turn off the light switch Through the building’s energy management system – turn off the lights Issues




People aren’t as productive in the dark Cost of Maintenance Personnel to manually turn on & off lights
Lighting Research Center

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
Lighting Research Center

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

Lighting Research Center

With funding from: U. S. Dept. of Energy; California Energy Commission; Connecticut Light & Power; New 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 Signal

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: Internet Hard wired to EMS Signal to Transmitter To Ballast

Power Line Carrier to Ballast

Dim Ballasts

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 $6/yr. $4/yr. $3.50/yr. $2.80/yr. $3/yr. $2.80/yr. $3.50/yr. Simple Payback 1.5 yrs. 2.25 yrs. 2.6 yrs. 3.2 yrs. 3.0 yrs. 3.2 yrs. 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
