Subject: Re: DOE DL2 Proposed Modification 

Hi Wes, Aaron and others, 

My recollection -- due warning, it is that of a layman -- is that two workgroups were formed for 

the MV work group. One devoted to general issues of data quality and replicability -- for design 

parameters of rep units and question of whether rep units are sufficiently representative. A 

second to deal specifically vault and network transformers, and to make recommendations on 

whether they should be treated as separate sub-category and if so how. 

My further recollection, which seems to have been corroborated by Wes's reply, is that for 

liquid-immersed there was reasonable concurrence with the view that while the rep units chosen 

might not perfectly reflect dominant market shares, they could be used (with the adjustments of 

the sort Wes describes herein) as a basis for extrapolating cost-efficiency estimates for units 

covering the market in that DL category. If so, then the chief charge of this data sub-group 

might be to confirm Wes's analysis and deal with any other data-quality-related concerns raised 

by Rob Greeson/Federal Pacific at our prior meeting. 

Hope this helps. Let me know if there are further questions. 

All best, 

Richard

Hi Aaron 
I do not understand what the charter is on any of the work groups. Hopefully Richard will provide some 

guidance. 

With regards to my comments on the representative unit for DL2.... in the attached I mapped 12 months 

worth of production to the ascertain how well the "representative" units matched what is moved in the real 

market place. 

As you can see 

 Pads - only RU5 actually was shipped and it was less than 1% of the pad market. 

 Poles - only RU2 actually was shipped and it was less than 1% of the pole market

At the KVA dimension RU2 represents 20% / 26% (units / MVA) of the pole market and 20% / 3% of the 

pad market. 

People should understand that the ratings selected as "representative" units DO NOT represent the 

market. 

However, with proper extrapolations, this data can be used to analyze the cost/efficiency characteristics

Wes, 

Help me understand what our charter is with respect to adjusting DL2?  I believe your contention is that the

parameters of DL2 are not representative of what is widely purchased in the market.  Is that solely based on kVA,

or is it more geared toward the primary voltage? 
 

Thanks and Best Regards,
