Well stated Jerry

That is also what my analysis and report said. If you restrict to M3 then the cost of EL1 rises to about

$20/watt.

To Mr. Parker and the DOE working group,

The reason for the request for the incremental cost of the losses is that the current DOE efficiency levels

can be obtained if the design is optimized at about $4 per core watt and $1 per winding watt at full

load. At the DOE 50% kVA rating, this is the same as evaluating th e losses or optimizing the design at

about $4 per total watts loss.

The present DOE efficiency loss level results in transformer designs about like many utilities were

purchasing their transformers before 2007. The utilities were purchasing the efficiency leve ls that werejustified based on the cost of losses. A few utilities were purchasing higher efficiency that the 2007

efficiency rules because of the calculated cost of energy being higher than the $4/$1 loss evaluation.

What came up in the discussion last week was even for loss level 1, the incremental cost of lo sses was

about $17 per watt for the design checked, between the present DOE losses an efficiency level of DEL1.

The added cost of $17 per watt is so much higher than the typical cost of the energy for the utilities,

that it is very questionable that the DOE payback esti mates are accurate. A 3% interest rate may be a

factor in the payback calculations.

Robert,

I understand the DOE staff are working on the incremental Watts calculations and will get that out to

group as soon as it's ready.

best wishes,

Richard

Thank you Richard. That clarification is helpful.In the liquid

‐ filled meeting we were told that we would receive an analysis of incremental Watts saved

by DL for all ELs, as well as the incremental cost. When will that analysis be available? For many of us,

that analysis is the basis for additional, perhaps extensive analyses, so it should come with e nough lead

time before any additional meetings or teleconferences to that we can give it the required

consideration. It would be most helpful if the incremental cost were provided separately for transformer

and installation, with any pole component of the installation identified.

For the MV Dry and LV Dry mee tings, it would be most helpful if you would also circulate an agenda with

objectives, hopefully this week, so that we are able to prepare for those meetings.

Dear Colleagues:

The telcon on the 17th is currently planned for medium

‐ voltage dry

‐ type and the telcon on the 21st is

reserved for low

‐ voltage. There will be revised analysis circulated in advance of both calls per our

discussion yesterday. Eac h call has substantial chunks of time allocated, though I hope we won't need

all that time.

It may be prudent to schedule a liquid

‐ filled call at some point as well, but I propose that we hold off on

that for day or so, until we can clarify wh en revised analysis for liquid

‐ filled will be ready.

Thanks for your very constructive participation in the meetings over the last two days.
