### All losses are taken into account . The optimization program reports the NLL and LL for any

design. If you want to see what th e loss of the design is at any lo ad factor, simply multiply the

LL by the square of the load factor and add the NLL. That's also how you can verify that the

field efficiency of the unit you receive tested at a 50% load is substantially less than the

efficiency Progress Energy experiences at you r reported 34% load. This calculation is

independent of the material used in the core and the coil.

Excellent points. Can anyone confirm that the consul tants are taking these higher load losses into account

that result from transformers with an amorphous core? I am conc erned that use of amorphous with

distribution transformers that have a high averag e loading (such as distribution transformers serving

industrial and commercial customers) will result in hi gher losses than those that may be realized with

silicon grain oriented steel.

This is a major concern for utilities.

Subject: RE: Negotiated Rulemaking - Distribution Transformers Teleconference

Good afternoon Robert and all:

I must disagree fundamentally with the way you have characterized the loss values. At night when the

load is light everywhere then the energy cost is also low and those who have time of day metering can

attest to it. If the load is as low as 10% then what is left is largely core loss and the generation is only

base generation at very low cost per kWH.During the day when the load is high the peak generators are all fired up and that is expensive energy.

There the winding losses are the big contribution to total transformer losses. Unfortunately when one

has an amorphous transformer that meets the same efficiency as an M3 transformer it has higher

winding losses than the M3. In the modeling that Jerry Corkran and I did we found that the amorphous

transformer had higher day time losses than the M3 which looks like it takes away from the enthusiasm

for amorphous cores as a National standard.

The bottom line is that core loss is not as valuable as winding loss on a watt for watt tradeoff.

Phil

### Steve,

### The statement that "reducing transformer losses pr imarily affects baseload, not peak" is a bit of

an over simplification. Reducing tr ansformer losses affects both base and peak. The value of the

loss at any point in time is then marginal cost or system lambda. That is, the value of reducing

transformer losses is the greater of the cost of the next unit that would have been dispatched, but

for the reduced load attributable to the transforme r, or the cost of gene ration from the last unit

actually dispatched, but used less due to the more efficient transformer. Because generation is

brought on line least-cost first, lo sses are evaluated in reverse order -- highest cost first. As Katie

Coughlin explained at the last meeting, this is the way LBNL evaluates benefits. Thus in the

early years, the more efficient transformer may ac tually save substantially more money than in

later years, when the older, higher cost units ha ve been retired. I don't believe this benefit is

picked up by the LBNL modeling, as it requires more detailed information -- at least hourly

marginal costs for each power pool.

Two comments. First, some comments have focused on just the market for M3 and amorphous steel. The

between M3 and amorphous at different standard levels should help us to address this. Second, reducing

transformer losses primarily affects baseload, not peak. So talking about cost per kW is misleading. An

efficient transformer is energized for more than 8000 hours per year. The average DSM measure saves for

about 3000 hours per year (although there is wide variation). If you want to compare, you'd need to

John’s points are well taken. Keep in mind that the DOE numbers indicate a payback at EL4 only if

amorphous steel is used. Thus, to assume that because it can be built using M3 steel, all is well, is totally

untrue. In John’s auto analogy, at least the customer has a choice of spending the extra money. In our

case, the customer will have no choice.

We all also need to understand that there is not an infinite supply of money to spend on efficiency

improvements. By forcing utilities to spend money on improving transformer efficiencies, we may very

well be taking money out of other efficiency programs which have a much higher payback than what is

being proposed here. In BGE’s case our package of efficiency programs cost us approximately $139 per

kilowatt saved. What is being proposed here is up to 100 times more costly. If BGE pulls back funds from

other efficiency programs to pay the high costs for transformer efficiencies, we would see a significant

decline in efficiency improvements overall.

Subject: RE: Negotiated Rulemaking - Distribution Transformers Teleconference

Robert

You continue to reference the ABB data presented by Wes Patterson as indicating that since a

transformer was sold at the EL3 or EL4 efficiency level that this level is cost effective. Specifically, you

state “Market sales data, however, is quite real. In this case it unambiguously says that the transformersat EL4 are an economically reasonable choice

‐‐ the market has, in fact, selected that choice on multiple

occasions”. This is simply NOT TRUE.

Just because a person buys as Jaguar for $100k that gets 25 mpg in place of a $40k Cadillac that gets 20

mpg; does NOT mean that the $60k delta will ever be “economically reasonable” for the extra 5 mpg.

You seem to be assuming that all of the transformers purchased from ABB that meet the efficiency

levels were purchased for efficiency reasons. This is simply not fact. The fact is that one large

transformer manufacturer was able to produce distribution transformers at EL3 and EL4 using M3 steel.

To my knowledge, Wes did not state the price for these transformers. In addition, just because one

company can produce this product doesn’t mean that all transformer manufacturers can make this

product at this level using M3 steel.

My hope is that we can all understand the facts and the analysis results better over the next few weeks

so that we can negotiate a solution that benefits the consumers, the ratepayers, the manufacturers, the

environment, etc. I plan to stay at the table till the end of the negotiation process.

### 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.

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

DOE makes the final decision on this, I would expect them to do “due diligence” in considering all the

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

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

Well stated Jerry

That is also what my analysis a nd 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 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.

### Robert,

I understand the DOE staff are working on the in cremental 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 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.
