RE: CASE NO. IPC-E-01-30 (Idaho Power)
BPA RESIDENTIAL AND SMALL FARM ENERGY RATE ADJUSTMENT
CREDIT
On August 31, 2001, Idaho Power Company (Idaho Power; Company) filed an
Application with the Idaho Public Utilities Commission (Commission) requesting approval of a
new tariff Schedule 98, which will implement a Bonneville Power Administration (BPA)
Residential and Small Farm Energy Credit (BPA Credit). The Credit for which approval is
sought is for the period October 1, 2001 through September 30, 2006. The Company requests an
effective date of October 1, 2001. The Company requests approval of the proposed accounting
entries that are required to track the BPA calculations and for related modifications to the Power
Cost Adjustment (PCA) calculation.
Settlement Agreement
In support of its Application, Idaho Power represents that it signed a Settlement
Agreement (Agreement) with BPA whereby Idaho Power received 120 aMW of benefits from
DECISION MEMORANDUM 1
the federal Columbia River Power System beginning October 1, 2001. The benefits provided for
under this Agreement are to be passed through and shared by the residential and small farm
customers of Idaho Power. Idaho Power Company’s Idaho residential and small farm customers
will receive 115 aMW of benefits. The Company’s customers in the state of Oregon will receive
5 aMW of benefits.
The Agreement between Idaho Power and BPA settles the parties’ rights and
obligations for the Residential Exchange Program provided for by the Northwest Regional Power
Act that was designed to benefit the residential and small farm customers of the Pacific
Northwest investor-owned utilities (IOUs).
The benefits of the Settlement Agreement consist of two components: a monetary
benefit and a firm power sale benefit. The monetary benefit is a direct payment each month by
BPA to Idaho Power and is determined by the difference between BPA’s forward flat-block price
forecast ($38/MWh) and BPA’s base residential load firm power (RL) rate ($19.76/MWh). The
Company proposes to calculate the power sale benefit as the difference between the average
monthly Mid-C price and the monthly residential load firm power (RL) rate. The Mid-C heavy
load hours (HLH) and light load hours (LLH) prices will be weighted by the amount of power
delivered in HLH and LLH hours. The RL rate, adjusted by BPA’s cost recovery adjustment
clause (CRAC), will be the actual amount billed to Idaho Power by BPA calculated on a daily
basis for each revenue month.
The Company has a number of additional options related to the firm power sale
component. Idaho Power may take delivery of power and calculate the value of this firm power
delivery. The Company may elect to terminate the Firm Power Sale Agreement and convert it to
the monetary benefit. Idaho Power Company retains the right to terminate the Firm Power Sale
Agreement up to 30 days after FERC grants interim approval for the BPA’s wholesale power
rates that are effective October 1, 2001. If the Company decides not to terminate the Firm Power
Sale Agreement, Idaho Power has the right to have all or a portion of the power delivered or not
delivered. If all or a portion of the power is not delivered, it is converted to a cash payment. The
cash payment is calculated as the difference between the average firm Mid-C index price for the
month and the BPA RL rate less wheeling and losses multiplied by the amount of power Idaho
Power does not schedule.
DECISION MEMORANDUM 2
BPA’s RL rate is subject to three cost recovery adjustment clauses (CRAC): a “load
base” (LB) CRAC, a “financial base” (FB) CRAC, and a “safety net” (SN) CRAC. The firm
power sale benefits are subject to all three CRAC amounts, whereas the monetary benefit is only
subject to the SN CRAC. The CRAC amounts will be calculated by BPA every six months.
Thus, a change in the CRAC amount will change the value of the benefits that flow to residential
and small farm customers.
Accounting
Benefits derived, as a result of the Settlement Agreement, will be deferred to Account
254—Other Regulatory Liabilities. Separate subaccounts will be used to distinguish between
residential and qualifying small farms by state. The monetary benefit and the net benefit value-
cost will be directly credited to Account 254 as well as interest calculated on qualifying small
farms retentions. Interest will be charged to Account 431—Other Interest Expense. The
payment for power deliveries taken at BPA energy prices will be charged to Account 555—
Purchased Power Expense. The benefit associated with the power deliveries taken, will be the
difference between the Mid-C price and the amount paid to the BPA for the power and will be
accounted for by debiting Account 557—Other Power Supply Expense and crediting Account
254. The result being that the charges to Account 555 and Account 557 will reflect a purchased
power expense amount equivalent to having purchased power at the average Mid-C price for the
month. Charges to Accounts 555 and 557 will be included in the calculation of the deferral of
power cost under the PCA mechanism.
Account 254 will be cleared (debited) and the offsetting credit being applied to
Account 142—Customer Accounts Receivable for the total benefit passed through to the
qualifying customers including any interest on qualifying small farms retentions.
Power Cost Adjustment (PCA) Modification
Without a modification to the PCA, the net benefits of the BPA power acquisition
will be distributed twice. The PCA calculations will reflect the same net benefit used to establish
credits on residential and small farm accounts. Three line item modifications to the PCA
calculation are required. Two of the line item modifications relate to the purchase power
expense for the 63 MW. The third line item modification is required to reflect the value of the
63 MW purchase in excess of the direct 63 MW purchase expense.
Benefit Distribution/Calculation
DECISION MEMORANDUM 3
The Company proposes to pass through the estimated benefit amount on a uniform
cents per kilowatt hour basis to all qualifying customers served under Schedules 1, 3, 24, and 25,
as well as Prairie Power schedules A and I. The calculation of the benefit for all residential
customers will be performed monthly and passed through beginning with the Cycle 1 billing
cycle commencing October 25, 2001. The calculation of benefit for qualifying irrigation
customers is, the Company states, much more problematic since the benefits may only be
received by irrigation customers with agricultural pumping loads 222,000 kilowatt hours per
month or less. Benefit dollars to be passed through to qualifying small farm loads will be
calculated monthly, but will be retained and passed through on an annual basis, concurrent with
the annual kWh and property tax rebate program.
The Company’s Application is accompanied by supporting testimony and exhibits.
On September 12, 2001, the Commission issued Notices of Application and
Modified Procedure in Case No. IPC-E-01-30. The deadline for filing written comments was
Thursday, September 20, 2001. The Commission Staff was the only party to file comments
(attached). Staff recommends that the Company’s Application be approved with the following
modifications:
1. The cost of delivered BPA power and the quantified benefit of that power that is
disbursed by Idaho Power to qualifying customers should be allocated to all
jurisdictions within the PCA like any other power supply expense.
2. The cost of delivered BPA power should be shared 90/10 by customers and Idaho
Power like any other non-QF power supply expense.
3. Benefits derived and paid by Idaho Power to qualifying customers for BPA power
delivered should be excluded from the 90/10 sharing provision of the PCA.
4. The Company should report monthly market prices, monthly energy use subject to
the credit and monthly credits paid in conjunction with current reports provided
for the PCA.
Staff’s recommendation does not change the calculation of benefits derived nor the benefits
returned to qualifying customers as a result of power purchases from BPA. It simply applies
existing PCA methodology to recover expenses associated with power actually delivered. The
only exception is that Idaho Power is not required to share the cost of benefits quantified and
returned to customers. Moreover, Staff recommendation assures that the FERC jurisdiction
DECISION MEMORANDUM 4
DECISION MEMORANDUM 5
shares in the cost of a BPA power purchase program that reduces system power supply costs in
other areas such as fuel, other power purchase expenses or increased power sales. Non-
qualifying customers in Idaho and Oregon share the BPA purchased power expense and, Staff
contends, so should the FERC jurisdiction as would be required for any other non-QF power
purchase expense.
Commission Decision
Idaho Power proposes to implement a tariff Schedule 98 BPA Residential and Small
Farm Energy Rate Adjustment Credit. Staff recommends approval of the Company’s
Application with modification. Idaho Power recommends that the Commission approve the
credit and requests an opportunity to file written comments regarding Staff’s proposed
modifications. Does the Commission find this procedure acceptable?
