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
