Example Lighting Retrofit Incentive
Measure:
Warehouse (100) 450W MH > 6 Lamp T5HO 350W
 12HRS/Day 7DAYS/Week
 Watt Reduction/Fix = 100W
 Hours /YR = 12Hrs * 7Days * 52Weeks = 4368Hrs
 Watt Hour Reduction = 100W * 100Fix * 4368Hrs = 4,368,0000 Whrs
 kWh Red = WH RED/1000 = 43,680 kWh
 Project Costs = @ $300/Fix = $30,000
Incentive is the lesser of:
35% of project cost -or-
$0.30/kWh (UI)
$.30 * 43680 = $13,104
35% * 30,000 = $ 10,500
Incentive = $10,500
