CASE NO. PAC-E-I0-07
November 2010
1 Q.Please state your name.
2 A.My name is Wiliam R. Griffith.
3 Q.Are you the same William R. Griffith who bas testified previously in this
4 case?
5 A.Yes I am.
6 Q.What is the purpose of your rebuttal testimony?
7 A.The purpose of my rebuttal testimony is to:
8 . Offer updated proposed rate spread and rate design exhibits that reflect
9 adjustments to the cost of service study to which the Company has agreed.
10 . Address the direct testimony of Mr. Bryan Lanspery of the Idao Public
11 Utilties Commssion staff ("Staff'), Dr. Don C. Reading of the Idao
12 Conservation League. ("ICL") and Ms. Teri Otens of the Community Action
13 Parership Association of Idaho ("CAP AI") concerning residential rate
14 design issues.
15 Updated Rate Spread and Rate Design Exhibits
16 Q.Pleas explain Exhibit No. 84.
17 A.Exhibit No. 84 contains a revise, proposed rate spread, bilg determnants, rate
18 designs, and monthy biling comparsons. These reflect the revenue requirment
19 revisions sponsored by Company witness Mr. Steven R. McDougal.
20 The proposed rate spread is consistent with the Company's proposal in its
21 diect case where the Company propose to alocate the price change to customers
22 in line with the cost of service results. The only exception to ths is for rate
23 schedule classes for which cost of service results suggest the need for price

decreases. For those customers, the Company proposes to make no change to
present rate levels.
Pleas describe the Company's proposal for the allocation of the rebuttal
revenue requirement.
The overall proposed price increase is 12.3 percent. The Company proposes the
following allocation of the base price increase:
Customer Class
Residential - Schedule 1
Residential - Schedule 36
General Service
Schedule 23/23A
Schedule 6/6A135/35A
Schedule 9
Schedule 19
Irgation

9.7%
13.3%
12.8%
10.8%
7.6%
18.2%
14.7%
0%
Mr. Lanpery for Staff proposes a uniform percentage rate spread for the
combined residential class--standard residential service Schedule 1 and time
of use Schedule 36-- rather than the separate cost-of-servce-based increases
propose by the Company for Schedule 1 and Schedule 36. Does the
Company agree with Staffs proposal?
No. The cost of service differences between Schedule 1 and 36 are consistent
with the Company's prior Idaho cost of service analyses using different test
periods. Those persistent differences should be reflected in the rate spread in ths
case.
Grifith, Di-Reb - 2
Rocky Mountai Power
1 As Mr. C. Craig Paice points out, in the 2008 general rate case the cost of
2 service results indicated that the cost of service-based increase for Schedule 36
3 was 1.8 times the increase for Schedule 1. In this current case, the cost of service
4 results indicate that Schedule 36 requires an increase equal to about 1.9 times the
5 increase necessar for Schedule 1. The differences between Schedule 1 and
6 Schedule 36 have been persistent in these cases, and they should be reflected in
7 the prices that customers pay.
8 We see no reason that Schedule 1 customers whose present average rates
9 are approximately 24 percent higher than Schedule 36 rates should continue to
10 subsidize Schedule 36. Even with the Company's proposed cost of service-based
11 change, Schedule 1 customers wil pay average rates 16 percent higher than
12 Schedule 36.
13 Residential Rate Design
14 Q.Please summarize the Company's residential rate design proposal for
15 Schedule 1.
16 A.The Company proposes replacing the curent monthly miimum bil and seasonal
17 flat energy charge residential rate design for Schedule 1 with a two-tiered inverted
18 block seasonal pricing strctue for energy use and a $12.00 fixed monthly
19 customer service charge. The Company proposes that the second inverted tier
20 apply to all usage in excess of 800 kWh per month. The Company chose to
21 termnate the first block at 800 kWh in order to reflect curent average usage on
22 Schedule 1 which is curently 839 kWh per month. Under the Company's
23 proposal, the average Idaho residential customer on Schedule 1 would see an

increase well below the average increase. Larger users with more discretionar
usage would see substantially larger increases.
Do parties support the Company's proposal?
Staff, ICL and CAP AI support an inverted energy charge rate design for
residential customers, but they propose a number of modifications to the
Company's proposal. Moreover, Staff and ICL believe that a $5.00 customer
charge would be appropriate and that, as indicated by Mr. Lanspery, the
Company's proposed $12.00 monthly basic charge is "too high". CAPAI opposes
fixed monthly charges in their entirety.
Does the Company agree with Staff's and ICL's proposed $5.00 customer
charge?
No. A $5.00 customer charge would fall far short of recoverig the fixed costs of
serving residential customers. As indicated in my diect testimony, the fied costs
of serving residential customers are over $29 per customer per month. A $5.00
per month customer charge would require that $24 permonth of fixed costs be
recovered through volumetrc energy charges rather than though fixed monthly
charges. Ths would send customers improper price signals, result in a high level
of intra-class subsidization, and lessen the abilty of the Company to have the
opportnity to recover the fixed costs of serving residential customers.
CAP AI opposes fixed monthly charges and indicates that other PacifiCorp
''sister companies" have residential customer charges "substatiay below
the $12.00 proposed in Idao." Pleae comment.
While the Company has customer charges lower than the proposed $12.00

customer charge in some jursdictions, it also has higher customer charges in
others. For example, prior to May 2009 in Wyoming, the Company had a
residential customer charge equal to $10.18 per month along with a flat energy
charge. In May 2009, Rocky Mountain Power implemented a two block inverted
rate along with a $20.00 residential monthly customer charge. Customer
acceptance of the new rate design strcture in Wyoming has been positive, and
the Company now has a fai opportnity to recover the fixed costs of serving its
residential customers. We believe that the Company's Idao proposal is also
moderate and fair. As indicated in my rebuttal Monthly Biling Comparisons
contained in Exhibit No. 84, Rocky Mountain Power's average Idaho Schedule 1
customers using 839 kWh per month wil see alost no change to their monthly
bils, while low usage customers wil pay a faier share of the fied costs of
serving them.
Please comment on Staffs and ICL's proposed inverted residential rate
designs.
As indicated above, the Company proposed a seasonally differentiated two block
inverted residential energy charge strctue where the first block would cover
usage from 0-800 kWh and the second block would cover all additional monthly
usage. Staff supports retaing the curent seasonal dierentiation, but it proposes
that different tiered rate block thesholds apply in different seasons- the first
block would be comprised of the first 700 kWh in the summer and the first 900
kWh in the winter. ICL proposes a thee block inverted residential rate design
and proposes dierent energy charge blocks in both the summer and winter

months.
Does the Company support Staffs proposed seasonally differentiated
inverted tiers?
No. The Company believes that these seasonaly differentiated tiers are
unnecessar and wil have little meaningful impact on customer usage. In fact,
they may increase customer confusion, parcularly durng the transition from the
existing flat rate to an inverted rate. As Mr. Lanspery indicates, "Rocky
Mountain Power customers in Idao have not faced anythg other than seasonal
flat rates since the 1970' s, at least." The Company believes that the proper way to
implement a transition to an inverted rate is to implement a single year round tier
with seasonally diferentiated prices. It is simpler and more easily understood by
customers.
Please comment on ICL's propósed seasonally differentiated three tier
inverted rate structure for Schedule 1.
ICL's proposed rate design greatly increases rate complexity and volatilty, and
the Company does not support it. ICL proposes three inverted rate tiers for
Schedule 1 in the summer and the diferent inverted rate tiers in the winter. In
the summer it proposes the following blocks: 0-700 kWh, 701-1800 kWh, and ::
1800 kWh. In the winter it proposes the following blocks: 0-1000 kWh, 1001-
3000 kWh, and :: 3000 kWh. It proposes the same rates in each of the the tiers
regardless of season. As a result of ICL' s proposal, customer usage for the first
700 kWh per month, for example, wil no longer be seasonally differentiated.
Ths seasonal change in the propose thee rate tiers wil introduce even

more rate complexity than does Staf's proposal, and it wil be confusing to
customers. It should be rejected by the Commssion. Again, the Company
believes that the proper way to implement a transition to an inverted residential
rate design is to implement a single year round tier. This was the Company's
proposal in Wyoming as discussed above. This supports the principle of
gradualism and can be more easily understood by customers.
Does the Company believe that ICL's proposal may produce unintended
consequences?
Yes it may. As the Schedule 1 rate design becomes more complex, customers
may simply choose to migrate to lower priced time-of-use Schedule 36, while
makng no change to their usage patterns, in order to avoid the higher third tier
prices and rate complexity of Schedule 1, paricularly large Schedule 1 users.
Please describe ICL's proposed revisions to residential time-of-use Schedule
36.
ICL proposes to "tu back the clock" on TOU Schedule 36. It proposes to lower
the customer charge from its curent level and to eliminate the curnt seasonal
diferential. ICL appears to ignore the fact that Idaho TOU customers have paid a
higher customer charge than ICL proposes, and they have paid seasonally
diferentiated energy charges for more than twenty years.
Doe the Company agree with ICL's proposls?
No. The Company believes that durng a time of rising costs, ICL's proposal to
reduce the curent TOU customer charge is unacceptable. It is-not cost-based,
does not reflect the curent cost environment, and sends an incorrect price signal

to TOU customers. In addition, the elimination of the seasonal differential for the
TOU rate, while continuing to retain seasonalty in the Schedule 1 rates, sends
confusing and conflcting signals to residential customers. ICL's proposed lower
customer charge and simpler TOU structue may enhance Schedule 36's appeal to
customers, paricularly large customers, choosing to avoid the higher prices on
Schedule 1. These customers may benefit from ICL's rate design while makng
no changes to their curent usage patterns. These improper price signals wil
produce unintended consequences if ICL's proposed rate designs are
implemented. ICL's proposals should be dismissed by the Commssion.
Has the Company performed any studies of residential rate structures?
Yes. The Company conducted telephone interview sureys of 405 randomly
selected Utah residential customers in September 2007 to assess their
understanding of Rocky Mountain Power's Utah residential rates. The
Company's Utah residential rate includes a three-tier inverted energy charge
strctue for the months of May though September.
What are the major findings of the study?
The major findings of the study are that most residential customers are unaware of
their electrc rates and usage. As reported by the surey respondents, 67 percent
do not know how much energy they use each month, 67 percent do not know
when their biling cycle begins and ends, and 86 percent do not know on average
how may kWh they use in a typical month. All of this inormation, plus
knowledge of the rate blocks and the amount of energy consumed durng the
bilg cycle at any given point in tie, is required to effectively receive a price

signal under an inverted rate design. When asked their preference, a majority of
customers, 54 percent, preferred a flat rate year round.
What were the Company's conclusions from these findings?
The Company concluded that the residential inverted rate strctue was not
understood by customers and was not signifcantly impacting consumption
decisions.
What lesson can be learned from this study for Idaho residential rate design?
The main lesson is that the vast majority of customers have little knowledge of
their electrc rate structure. Because of this, rates should be easily understood and
structual changes to rates should be minimized. Staff s and ICL's proposals to
change the rate block structure twice a year, and ICL's additional proposal to
implement a third invertd rate tier, would have little impact on actual customer
usage whie increasing rate complexity and confusion. The Company believes the
transition from the current flat Schedule 1 energy charge should move towar a
simple, year round two-block inverted rate strctue. This wil assure a smooth
transition to an inverted rate design and wil assure that rates are easy to
understand for our customers.
Doe this conclude your rebutt testimony?
Yes.
