### Greetings!

With all due respect, I think that some people are forgetting that there can be a

“regulatory lag” between when ex penses are paid and when the recovery period starts.

For example, the expense may be in year 1, but the recovery may not start until year 4.

In addition, the attached slides show declini ng ROE’s for utilities, which means that the

payback periods are even longer.

### Chuck,

I think you'll find that consumer electric bills actually fall. The in crease in cost to the consumer

is the depreciation and return (with the equity portion grossed up for taxes) on the incremental

transformer cost. As a simplification, I typi cally levelize the combined return and the

depreciation (a mortgage payment, if you will) ra ther than dealing with a declining return over

time. Thus only 1/30th of the incremental cost (including return and taxes) is paid by the

consumer each year. This is offset by the full e fficiency gain each year -- the full reduction in

generation and fuel cost. Regulator y accounting results in the consumer realizing benefits in year

1 rather than at the end of the payback period. In this negotiating envi ronment I believe that

viewing the implications through the lens of utility ratemaking and cost / kWh would be more

familiar than the LCC framework, it was determined that such analyses were sufficiently similar

to the LCC approach and that even th e small added cost was not justified.

I understand that ABB is only one vendor, but my understanding is that they are the largest. I

also understand that they don't focus on a single market segment at the expense of others.

Accordingly, although not a true random sample fo r purposes of probability, I'm satisfied that the

data are sufficiently representative of the market for our purposes.

It is also important to note that the current period is deci dedly not the same as the 2004-2007

period. The shortages and rationing that occurre d during that period was the result of a

confluence of several complex f actors, one of which was the de mand by domestic transformer

manufacturers that you mention. I don't see those f actors in the current market. Although due to

the limited competition in the domestic steel market, one cannot totally dismiss the possibility of

a recurrence of 2004-2007, the size of the international mark et significantly re duces the risk of

such recurrance. In any case, the 2004-2007 phenomenon clearly had nothing to do with

efficiency; nor do I believe that an increased focu s on efficiency would significantly increase the

likelihood of such recurren ce. Hope that helps.

Robert:

The perspective of Users is that the first-time, up -front costs of (slightly) more efficient distribution

transformers will result in consumers paying much mo re for electric service. Even though the “model”

predicts some type of LCC savings over extremely lo ng periods of time, I am very doubtful that the

American public will ever realize any of these savings. The current efficiency requirements that the DOE

implemented on 1/1/2010 already force very efficient tr ansformers (as Steve Rosenstock’s email to Steve

Nadel of earlier today showed, the DOE required signi ficantly higher efficiencies in the Final Ruling than

the NOPR indicated). Squeezing a few more Watts at a significantly higher transformer cost does not

make any sense.

As far as the ABB data, you need to consider that this data is from one vendor that controls a part of the

overall market. If all distribution transformer vendors ha d to supply transformers with an EL4 efficiency

in an environment similar to that of 2004-2007, then we will most assuredly run out of product unless we

can repair enough older transformers to fill the n eed. Core steel was being rationed during 2004-2007

because of the severe demand for transformers (large, medium, small and distribution class

transformers all rely on M3 grade core steel to a large extent – and will do so even more if the efficiency

levels are increased). We, as Users, had a hard tim e purchasing enough distribution transformers to fill

our customer’s needs during the 2004-2007 time period. Anyone that tries to make the rationale that just

because ABB made transformers with M3 core steel th at met the EL4 efficiency level and therefore, all

distribution transformers should be required to do the same isn’t getting the “big picture”. If all

transformer manufacturers have to use M2, M3 and/or amorphous core steel to meet an EL4 efficiency

level, the reliability of the US electric system is going to go right into the dirt.

We as Users want to reach some type of consensus on whether any change in efficiency levels are

necessary, and if so, what should they be. Howeve r, we have to represent our customers who we are

charged with providing reliable and reasonably priced electric service and efficiency levels of EL4 will

not allow us to do so.Regards,

### Bruce,

Those upfront transformer costs ar e compared to the fuel cost savings in the LCC approach. The

discounting process values fuel cost saving in the future at less than the costs in curred today. The

positive LCC means that that the efficiency a dvocates are not ignoring costs, but comparing

them with benefits and finding that the consumer is better off and will be paying less. One does

not, however, need to rely on the LBL analysis to see this. The ABB sales data shows M3

transformers being delivered at EL4 efficiency. As a modeler, I am always skeptical of model

results -- people do not live in computers and certainly not on in some of the back-of-theenvelope calculations that we have seen from others. Market sales data, however, is quite real. In

this case it unambiguously says that the tran sformers at EL4 are an economically reasonable

choice -- the market has, in fact, selected that choice on multiple occasions.

To the extent that there are dug-in positions, again the evidence does not support that it is the

efficiency advocates that ar e dug-in. Although EL4 is achievabl e and beneficial based both on

market data and LBL analyses, the proponents of greater efficiency indicated a willingness to

compromise. It is certain repr esentatives of the industry who ha ve consistently said either no

change, or a fractional change. It is those industry re presentatives who appear to be advancing

### the "my position or nothing" attitude. Although I happen to agree that substantial movement

towards more efficient distribution systems, I also note that these are incredibly expensive

meetings. We have a large number of very se nior people devoting s ubstantial time to the

meetings, their preparation and non-trivial trav el costs. These peopl e have other things

competing for their time. If you and others hone stly believe that you cannot agree to a higher

standard, and place no value on regulatory certain ty, then let's not waste additional time and

money. Let's just say that we gave it a good shot, cut our losses here, and make our respective

cases to DOE outside the negotiation process and let DOE make it's own decision. I believe that

they certainly have sufficient in formation to support their positi on in a February NOPR. I can't

imagine what else they would need.

It appears that negotiation to you is defined as agreeing with your position

unfortunate that you believe the American public, especially in these trying economic times, should be

in the distant future

This is not a “cut and dried” economic decision but is one that needs to be taken seriously for the major

impact it could have on the electric supply of the US and the financial position of the American public. IfDOE makes the final decision on this, I would expect them to do “due diligence” in considering all the

effects there decision would have on US businesses and the US economy.

Let it be known that the Utility Industry has not pulled out of the negotiation process and will continue

to work with DOE to reach the right decision.

Phil,

We're in the middle of negotiations and some of us have made clear that no or little change to the

standard is not acceptable as the DOE analysis just ifies higher standards (higher levels are technically

feasible and cost-effective on a life-cycle cost basi s). The efficiency groups would rather leave the

decision to DOE than agree to subpar standards. If you and other participants want to veto any

significant change in the standard, th en we might as well save some time , break off negoti ations and just

make our respective arguments to DOE. Is that what yo u want to do? If the answ er is no, then let's start

talking about how to make higher standards acceptable rather than continue to make arguments about

why low standards are needed. We're all busy and if we're going to ma ke progress we need to break new

ground and not rehash old ground.

Hello Robert and all:You must not have looked at Jerry Corkran’s message because he found the cost to be $17/watt, which

is pretty close to my number, where both Jerry and I have used M3 core steel to derive the cost curve.

The fact is that the cost curve is very steep with M3 and quickly hits the brick wall.

1. I have checked Carlos Gaytan’s cost curves as well and he is finding about the same relationship with

M3.

2. I have checked Wes Patterson’s data as well and he is finding an M3 cost curve about the same as

mine.

3. I have checked the OPS data with M3 as well and it too is very close to $20/watt.

a. For example, for design line 1 they show an efficiency at 50% load of 99.08% which translates to 232

watts of loss and sells for $1,960.73.

b. They show another M3 design with an efficiency of 99.26% which translates to 186 watts of loss and

sells for $2962.11.

c. The change in selling price is $2,962.11

‐ $1,906.11 or +$1,001.38

d. The change in watts is 232

‐ 186 or ‐ 46 watts.

e. The OPS $/watt is therefore, $1,001.38/46 watts or $21.77

f. Hence we see that all data sources are pointing to cost per watt of ~$20 /watt saved to go from the

current mandatory standard to EL1. I get $30/watt to go to EL2 and $53/watt to go to EL3

4. The fact is that M3 is about out of gas and the DOE did a good job in the last rule making.

5. The fact also is that a push to anything beyond present does not show economic value and I do not

support it.

6. The fact also is that a push to higher efficiencies will kill the new transformer market and open up the

rebuild market, destroying jobs at the new transformer manufacturers and resulting in transformers of

lower efficiency which will cost energy and not save it.

### Even if it were that high (and Mr. Hopkinson is the only one I've seen who has put the number

anywhere near that), the effi ciency objective is saving Watt- hours (energy) not Watts (the

capacity to save energy) . One Watt saved fo r 8,760 hours per year for 30 years is 262.8 kWh

(not counting leap years). Even at Mr. Hutchi nson's $20, that's just over 7¢ / kWh. If Mr.

Hutchinson will examine his electric bill, as he ha s reported, he will see that even as high as 7¢

it's a good buy, and that assumes we put a ZERO valu e on any environmental benefits (which is

why DOE agreed to reconsider its 2007 MEPS in the first place.

Indeed, the cost of losses per Watt (roughly the A factors that O PS has been using) are no where

near the $20 claimed here. Moreover, as ABB and others have pointed out, the proper approach

would have been to minimize cost subject to e fficiency, not A & B, which would have resulted

in a lower, flatter curve to the asymptote. ABB's actual market data -- physical transformers

produced and delivered -- shows a competitive market for M3 transformers even at EL4

efficiency. You can make all the hypothe tical claims you want to, gentlemen, the market is

the real world

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 the 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 levels that were

justified 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 losses 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 estimates are accurate. A 3% interest rate may be a

factor in the payback calculations.

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 a dditional, perhaps extensiv e analyses, so it should

come with enough lead time before any additional meetings or teleconferences to that we can

give it the required consideration. It would be most helpful if th e incremental cost were provided

separately for transformer and installation, with any pole component of the installation identified.

For the MV Dry and LV Dry meetings, 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 circulat ed in advance of both

calls per our discussion yesterday. Each call has substantia l 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 when revised analysis for liquid-filled will be

ready.

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