BEFORE THE IDAHO PUBLIC UTILITIES COMMISSION
IN THE MATTER OF THE
APPLICATION OF ROCKY
MOUNTAIN POWER FOR APPROVAL
OF CHANGES TO ITS ELECTRIC
SERVICE SCHEDULES
CASE NO. PAC-07-
Rebuttal Testimony
of William R. Griffith
ROCKY MOUNTAIN POWER
CASE NO. PAC-07-
October 2007
Please state your name, business address and present position with the
Company (also referred to as Rocky Mountain Power).
My name is William R. Griffith. My business address is 825 NE Multnomah
Street, Suite 2000, Portland, Oregon 97232. My present position is Director
Pricing, Cost of Service & Regulatory Operations in the Regulation Department.
Are you the same William R. Griffith that previously submitted testimony in
this proceeding?
Yes.
What is the purpose of your rebuttal testimony?
The purpose of my rebuttal testimony is to:
Offer updated proposed rate spread and rate design exhibits that reflect
adjustments to the cost of service study to which the Company has agreed.
Address the direct testimony of Mr. Timothy Shurtz concerning customer
noticing of the general rate case.
Address the direct testimony of Mr. Anthony Yankel testifying for the Idaho
Irrigation Pumpers Association (lIP A) concerning rate design for Schedule 10
customers.
Address the direct testimony of Mr. Bryan Lanspery for the Idaho Public
Utilities Commission Staff concerning rate spread and tariff applicability.
Updated Rate Spread and Rate Design Exhibits
Please explain Exhibit No. 53.
Exhibit No. 53 contains a revised, proposed rate spread along with billing
determinants, proposed rate designs for all rate schedules in this case, and
Griffith, Di-Reb -
Rocky Mountain Power
monthly billing comparisons. These reflect the revisions to the cost of service
model discussed by Company witness Mr. Mark E. Tucker along with the revenue
requirement revisions sponsored by Company witness Mr. Steven R. McDougal.
The proposed rate spread is consistent with the Company s proposal in its
direct case where the Company proposed uniform percentage increases for
residential and irrigation customers along with larger increases for street and area
lighting customers and contract customers. No changes are proposed for other
rate schedule customers.
In a similar manner, the design of proposed rates is consistent with the
methodology in the company s direct case, except that the proposed rates now
reflect the revised revenue requirement and rate spread in the Company s rebuttal
case.
Response to Testimony of Mr. Timothy Shurtz
Do you agree with Mr. Timothy Shurtz s direct testimony wherein he
indicates that Rocky Mountain Power provided "inadequate notice to rate
payers
No. The Idaho Public Utilities Commission s Rules 102., 102., and 102.
specify customer noticing requirements for general rate cases. As indicated by the
Commission staff in Mr. Daniel Klein s direct testimony, the company complied
with the Idaho Public Utilities Commission s noticing requirements for general
rate cases. While Mr. Shurtz might believe that additional requirements should be
put in place, the Commission s current requirements have been met by the
Company in this docket.
Griffith, Di-Reb - 2
Rocky Mountain Power
What notice did the Company provide?
Rocky Mountain Power issued a press release on the day of filing (Rule 102.04)
and sent a bill insert to all Idaho customers (Rule 102.03). The bill insert was
distributed to all customers over the course of a billing cycle, and complied with
the information requirements specified in Rule 102.01. Rocky Mountain Power
also immediately made the filing available at our local offices (Rule 102.01).
What is the appropriate forum for determining the adequacy of the
Commission s current noticing requirements?
As previously noted, the Company complied with the Idaho Public Utilities
Commission s noticing requirements for general rate cases in this proceeding.
However, if Mr. Shurtz believes additional requirements are needed, the
appropriate forum for the review of noticing requirements is a rulemaking
proceeding, not a general rate case, because the noticing requirements would
apply to all utilities regulated by the Commission, not just Rocky Mountain
Power.
Response to Testimony of the Idaho Irrigation Pumpers Association
Please respond to Mr. Anthony Yankel's recommendation that Rocky
Mountain Power offer a time of use rate for irrigation (Schedule 10)
customers.
Rocky Mountain Power does not believe Mr. Yankel's proposed time of use rate
option is complete nor reasonable.
Griffith, Di-Reb - 3
Rocky Mountain Power
Please explain.
The Company has not proposed a time of use rate for irrigation customers in this
docket. The proposal filed by IIP A is incomplete. It contains no workpapers or
cost basis for the proposed time periods or rate differentials. Moreover, IIP A
recommends that "something more like super-peak price be developed" that
perfectly overlaps the irrigation load control demand side management program
timeframe using "the same 4-days per week.. . and the same 6-hours per day (2:00
m. until 8:00 p.
Is it reasonable that liP A's on-peak period proposed in its time of use rate
design proposal perfectly overlap the current Irrigation Load Control
demand side management program s applicable timeframe?
No. We do not believe that IIPA's limited proposal is reasonable. Under IIPA'
proposal, customers participating in both the irrigation load control demand side
management program and a time of use rate would receive double payment-first
the Company would pay customers for their on-peak demand side management
efforts through the irrigation load control program and, second, the Company
would provide time-of-use tariff discounts to those customers for avoiding on-
peak usage. While this would be a good deal for recipients, it is not reasonable to
pay customers twice under lIP A's proposal. IIP A does not address this double
payment issue.
Griffith, Di-Reb - 4
Rocky Mountain Power
Would a tariff restriction limiting customers who participate in the irrigation
load control demand side management program from participating in the
time of use option solve this problem?
It might. However, this has not been addressed in IIPA's proposal.
What is Rocky Mountain Power s recommendation concerning liP A's time
of use proposal?
As discussed above, IIP A's proposal is incomplete and, in light of the current load
control demand side management program, could result in excessive credits to
irrigation customers. The Company recommends lIP A's time of use proposal be
rejected.
Following this general rate case, would Rocky Mountain Power be willing to
work with liP A and other parties to attempt to develop an appropriate time
of use rate proposal?
Yes. The Company would be willing to work with IIP A and other interested
parties on a more thorough analysis to determine the feasibility of such a program.
If such a program were developed, it could be introduced at the time the Company
filed its next general rate case.
Response to Testimony of Commission Staff
The direct testimony of Mr. Bryan Lanspery for the Commission staff
recommends that the street lighting class s rate be increased so that
customers are paying rates equal to their full cost of service. Please compare
his recommendation with the Company
The company s direct proposal recommended increasing street lighting rates by
Griffith, Di-Reb - 5
Rocky Mountain Power
approximately two times the overall price change, and made substantial
movement toward full cost of service. Staff s recommendation results in an
increase of approximately four times the Company s proposal.
Does Rocky Mountain Power agree with Staff's proposal?
The Company believes that each of the proposals has value and recommends that
the Commission weigh the merits of the two approaches.
Staff has recommended that the Company clarify the eligibility criteria for
Schedule 23, General Service, and Schedule 6, General Service - Large
Power. Please comment on Staff's recommendation.
Currently, Schedules 23 and 6 are available to all general service customers.
Schedule 23 is an energy-only rate that applies to all non-demand metered
customers. It also benefits low load factor general service customers including
those with demand meters.
Schedule 6 has both demand and energy charges; it benefits customers
with higher load factors. Along with the presence of a demand charge in Schedule
, the Schedule 6 energy charge is about one third the Schedule 23 energy charge.
These rate structures have been in place in Idaho for well over two decades
and have been optional rates for customers. When a new customer signs up for
service, Rocky Mountain Power analyzes the customer s expected usage
characteristics and recommends placing the customer on the most advantageous
rate for the customer. Customers have been permitted to choose from these two
rates based upon their individual circumstances.
Griffith, Di-Reb - 6
Rocky Mountain Power
Is the Company willing to clarify the eligibility criteria for Schedule 23,
General Service, and Schedule 6, General Service - Large Power?
Yes. The Company is willing to work with Staff to clarify the eligibility criteria
of Schedule 23 and Schedule 6. However, we note that if the current eligibility
criteria are revised in such a way that the optional nature of the current rate
schedules is eliminated that such a change will likely have rate impacts on
customers. We recommend that this eligibility criteria review with Staff occur
following the completion of this general rate case and that any revisions be
proposed in the Company s next general rate case in order to properly reflect the
revenue impacts of any change.
Does this conclude your rebuttal testimony?
Yes.
