These are documented payback periods based on customers
actual utility bills, using their local EDC & LDC utility rates . . .  
and the true incremental value of the energy units saved.
 

       


'Typical' payback periods of some Energy Conservation Measures (ECMs)

Energy Management payback periods vary based on conditions found while
conducting the ENERGY AUDIT on a facility. Factors affecting payback periods
include your local electrical and natural gas costs, mechanical & electrical
systems, hours of operation, present manual and automatic controls, condition
of building systems and other factors.
