Chris:

In yesterday’s teleconference Wes and I questioned why the “A” values were so high in Figure 1 of the

ERAC MEMO. I have reviewed the attached memo I think I see the problem.

You have put the “A” and “B” values on a Present Worth basis instead of on an Equivalent First Cost

basis. The electric utilities, almost a 100%, use the Equivalent First Cost basis for their “A” and “B”

values, so they can add the cost of the losses directly to the quoted price. Otherwise we’d be mixing

apples and oranges in the TOC evaluation.

From the second exhibit, if you are given Present Worth and want to convert to Equivalent First Cost the

you would multiply the Present Worth by (1/FCR)*(1/PW Factor).

For a fixed charge rate of 20% or .2 per unit and a PWF of 12.4 @ 7% for 30 years, the value of

(FCR*PWF) becomes

= 2.48. So the “A” and “B” factors per the ERAC Memo are 2

‐ 1/2 times the values

the electric utility would calculate on an equivalent first cost basis. If LBNL and Navigant used the ERAC

Memo for determining the “A” and “B” factors, the life cycle costs/saving would be overstated by a

factor of 2

‐ 1/2. This should explain why the “A” values in Figure 1 appeared to be so high.

I look forward to your reply on this matter & thank you again for all your patience and hard work on this

LCC analysis.

Regards,

Bob Smith, PE

Dear Chris:

Per our teleconference yesterday I am very, very interested in what value you calculate for the “A”

coefficient. If your calculation is different than the one shown on page 24, I hope you will supply an

explanation. You do not need to bother with the calculation of “B”

, as it is based on exactly the same

utility costs as for “A” except there are some other variables like responsibility factor, loss factor, and K 2,

all of which we will continue to debate about

.

I’ve confined my calculations to the end of each year instead of the beginning of each year.

Do not worry about the “C” and “D” factors. They are not very significant and most utilities don’t bother

with using them.

Please try to digest the table on page 16. There is a lot of confusion on the difference between

Equivalent First Cost and Present Worth.Please try to become familiar with the “encircled” definitions on pages 10

‐ 12.

On pages 6 through 9A I list the owning formulas for the utilities as known in 1978. While the “A” and

“B” values of today are about double or triple those shown, the ratios should have stayed the same,

unless the utility has changed its loading practices.

In your model you have assumed a 50% NP loading. In the attachment all loading is a function of Peak

Loading and assumes load growth from the time of original installation. As you can see, it is not unusual

for a utility to change out a transformer when it reaches 160% of Nameplate of peak loading. I point

this out so that you can remember that in today’s transformers there is a lot of extra thermal capacity

that will not be utilized under the DOE 50% loading assumption. But I can assure you, that if we raise

the efficiencies of our transformers by 2 or 3 EL levels and the price goes up another 20 or 30%, utilities

will take advantage of the thermal capacity of our transformers and buy smaller KVA ratings for their

initial installations. So as the load grows we’ll experience just the opposite of our intended effect of

lowering the energy needed for transformer losses.

I look forward to your answer on the correct value of the “A” factor.

Regards,

Bob Smith, PE

Subject: MVLI LCC & NIA - Loading Information

Dear Chris,

At the last liquid

‐ immersed distribution transformer working group meeting, we were chatting about

the loading assumptions that were built into the LCC model. You had commented that there was very

little actual loading information from which to build the model, especially as it pertains to commercial &

industrial as well as larger kVA single

‐ and three

‐ phase units (larger single phase pole mount units are

often ganged to provide three phase service), so the loading information that was available was scaled

across everything. You had stated that you would appreciate any actual loading information that I could

provide.

Below I’ve pasted the loading information provided by We Energies. We Energies serves over 1 million

customers in Wisconsin and Michigan’s Upper Peninsula. The data is quite recent and therefore, should

be relevant.

These values are more in line with the information that other utilities had provided during verbal

interviews. Armed with this information, how difficult would it be to run life

‐ cycle cost and national

impact analysis with these loading levels instead of the 25

‐ 30% load distributions used previously?

Thanks and Best Regards,

Aaron

### Aaron,

### In 2008 we established new A and B factors. At that time we relooked atour load factors in

order to determine the most accurate A and B factor s we could. We used customer data from our

metering group as well as our company design practices to establish these f actors and they are as

follows:

1-phase 3-phase

42% loaded 55% loaded

If there are further questions on these please let me know.
