Four hurdles EnergyDrive OvercomesNEED FOR CAPEX FINANCE:

Typical installation paybacks are in excess of 3 years

THE MEASUREMENT AND VERIFICATION DILEMMA: How to create a verified, realistic base line, and track the actual savings

PLANT DOWN TIME: The risk that VSD failure can cause plant down time, thereby wiping out any

savings created

TECHNICAL RESOURCES: Finding the technical staff for such projects
