Gulf Coast CHP - Laundries

Laundries

Why is CHP a good technical fit for commercial dry-cleaning and laundry facilities?

Operates at least 5 days a week, approximately 12 hours per day
Large quantities of heat/steam consumed
Large quantities of hot water consumed

Typical Commercial/Industrial Laundry Heat Loads:

Tempered water (90 °F - 105 °F)
Hot water (140 °F - 170 °F)

Temperature dependent on laundry type

Clothes dryers
Steam tunnel

Current Status

There is over 4.5 MW of installed capacity in laundry facilities in the U.S. This capacity is found in six states with California and New York clear leaders. The majority of these systems utilize reciprocating engines and natural gas.

State	Installed Capacity (in kW)
CA	2,062
NY	1,360
IL	470
NJ	455
CT	120
CO	40
U.S. Total	4,507
