Written Responses - 11 John Amy - Navy The Navy answer is 2-4 years. Subhashish Bhattacharya North Carolina State University – Less than 2-3 years Roger Cooley Northrup Grumman – Efficiency numbers are believed more than “payback period” Geoffrey Dolan Google – This seems too application specific. The goal should be reduction in overall system cost at installation. Small premiums may be supported for efficiency but goal for mass adoption should be lower installed system cost. Krstic Slobodan Corporation –Eaton 1-2 years Stephen Kuznetsov Raytheon – 3 year payback essential Veli-Matti Leppanen ABB – Maybe there could be incentives via some sort of leasing arrangements -the savings could be split between equipment provider and end user. Tim McCoy McCoy Consulting – 3 years or less for commercial applications John Shegirian General Dynamics – 3 years Brij N. Singh - John Deere Inc. Increased efficiency and increased performance offered with medium and high voltage inverter could result into a realistic payback period of two to three years. If there are additional advantages such as reduced size and improved fuel economy in case of transportation applications for heavy-duty vehicle could be a good customer pull to generate strong market interest. Ajith Wijenayake DRS – Preferably less than five years (similar to typical payback periods in the commercial drive industry) but may be different for different applications and should consider individual applications. Key Question 1c. What are efficiency benefits that would warrant incentives?
