Honeywell (Minneapolis, Minnesota) has announced a $4.25 million permanent load-shifting program with Southern California Edison (SCE; Rosemead, California) that will reduce the utility bills of commercial customers and decrease electricity consumption during peak day-time hours.
The Night Shift program is expected to deliver 2.5 MW of peak-power relief between noon and 6 p.m.
Honeywell will manage the program for SCE, retrofitting approximately 300 rooftop air conditioners with Ice Bear hybrid air-conditioning units from Ice Energy. The Ice Bear system freezes water in a storage tank at night when electricity costs are low. When the air conditioner is on in the day, the stored ice cools the refrigerant instead of a condensing unit. As a result, the modules cut peak cooling demand by up to 95%.
