Subject: Engineering Data Exchange

MV Committee Members,

Several of the group have proposed that DOE facilitate a bidirectional exchange of engineering data.

Attached is one kind of template that could be used to compare the ways in which different parties can

achieve certain efficiency levels. DOE would populate the spreadsheet with detailed design information

for the le ast cost transformers able to achieve the draft efficiency levels using different steels.

Data provided to DOE could then be compared to the DOE designs and differences explained. Because

this data would likely be considered confidential, Navigant is willing to enter into nondisclosure

agreements with any party submitting such data. Th is process would first be used to verify theengineering analysis of the current representative units and could be expanded to analyze scaling

relationships.

We welcome comments and specific suggestions of how this process could be implemented.

Best,

Brian Coffey
