Wes,

On the slides, the title "Open Wound Core Grade Di stribution" -- are these wound-&-annealed or mitered core designs?

Thanks, Jerry

## Hi Richard

For the discussion on MVDT I would like to add the following steel distribution analysis required to produce open wound transformers at the varying dEL levels.

This data was determined by reviewing actual ship ment records over a 12 month period June 2010 to June 2011. The products are largely in the DL12 space (3ph, 95BIL, 1500-200KVA).

I agree that a focus on DL12 will focus the conversation.

But I would like to emphasize that, assuming we can a rrive at a significant improvement in the efficiency of DL12, we will not be able to match the same improvement for

 MVDT single-phase products

 MVDT small three-phase products (<= 300KVA)

 MVDT products with BIL's > 95KV

Perhaps we can agree to work out these details with the DOE following the teleconference?

Best regards Wes

Richard Parker

cc Subject Today's Conference Call on Medium-Voltage Transformers



# Dear Colleagues,

As you know, today's conference call is the last scheduled event of our negotiated rulemaking process on medium-voltage transformers. It is scheduled to run from 11 am to 1 pm, though we will end sooner if we finish our business sooner.

I propose that we use th e time to do two things:

1) See if we can get to yes on an EL to recommend for DL 12, th ereby creating a clear foundation an agreement on MVDT.

I propose to focus on DL 12 because DLs 9, 10, and 11 are very small in sales (about 5 % of the market combined). E.g., 135 DL 11 units shi pped in in 2009, whereas 1936 DL 12 units were sold.

Also, these other DLs should scale off of DL 12 , except for the low kVA portion (< 300 KvA) of DL 11 which is even smaller. DL 13 is a high-BIL version of DL 12 (and the upper end of DL11) and also can be treated as variant of DL12. Adjustment factors for DLs 9, 10, 11 and 13 have been proposed by NEMA, but I would suggest that these can be treated separately as part of a technical exercise, that we can discuss if we can get to yes on the big issue, which is DL 12

2) Discuss next steps, if any, for th is group on liquid-filled transformers.

Attached for your review is a chart containi ng the key LCC information for DL 12, with 2010 price results and 2011 price results displayed side-by-side for ease of reference. Also attached are the full LBL and Engineeri ng Analysis results for both 2 010 prices and 2011 prices. 2011 prices are what were are focusi ng on, but 2010 prices offers a useful reference (sensitivity if you will).

I look forward to talking with you at 11. This wi ll be a time for bottom lines. We know the arguments.

Best, Richard Parker
