IN THE MATTER OF IDAHO POWER
COMPANY'S PETITION TO MODIFY THE
METHODOLOGY FOR DETERMINING FUEL
COSTS USED TO ESTABLISH PUBLISHED
RATES FOR PURPA QUALIFYING FACILITIES
CASE NO. IPC-O7-
COMMENTS OF THE
COMMISSION STAFF
COMES NOW the Staff of the Idaho Public Utilities Commission, by and through its
Attorney of record, Scott Woodbury, Deputy Attorney General, and in response to the Notice of
Petition, Notice of Modified Procedure and Notice of Comment /Protest Deadline issued on
September 27 2007, submits the following comments.
Pursuant to the Public Utility Regulatory Policies Act of 1978 (PURP A) and the
implementing regulations of the Federal Energy Regulatory Commission (FERC), the Idaho
Public Utilities Commission (Commission) has approved a methodology for calculation ofthe
avoided cost rates paid to PURP A qualifying cogeneration and small power production facilities
(QFs) by Idaho Power Company, Avista Corporation and PacifiCorp. Avoided cost rates are the
purchase price paid to QFs for purchases of QF capacity and energy.
On September 10, 2007, Idaho Power Company (Idaho Power; Company) filed a Petition
with the Idaho Public Utilities Commission (Commission) to modify the methodology for
determining fuel costs used to establish published rates for PURP A QFs. Idaho Power contends
STAFF COMMENTS OCTOBER 23 , 2007
that use of the current method to set the fuel cost component in the surrogate avoided resource
(SAR) methodology will result in published avoided cost rates that are not representative of the
costs Idaho Power is likely to avoid by purchasing energy from QFs.
BACKGROUND
In Order No. 29124 issued September 26 2002 in Case No. GNR-02-, the
Commission established the methodology currently used to compute the fuel cost component of
the surrogate avoided resource (SAR) methodology. For QF projects generating less than
aMW, the avoided cost rates determined by the SAR methodology are commonly referred to as
the published rates. The current SAR is a natural gas-fired combined cycle combustion turbine.
In accordance with Order No. 29124, the release of a new forecast by the Northwest Power and
Conservation Council (NWPCC; Council) triggers a recomputation of the published avoided cost
rates.
The method the Commission adopted in Order No. 29124 to calculate the fuel cost
component in the SAR methodology starts with an arithmetic average of the nominal prices for
natural gas for the first 3 years of the Council's median 20-year forecast of natural gas prices.
These three years consist of the current year s forecasted price, plus the previous two years
forecasted prices. The SAR methodology then escalates that 3-year average natural gas price at a
uniform percent per year over 20 years. The escalation rate is also calculated from the NWPCC
20-year natural gas forecast.
ST AFF ANAL YSIS
On September 11 , 2007, the NWPCC released a new forecast of natural gas prices.
Unlike past forecasts that predicted gradually increasing prices over the 20 years of the forecast
the new forecast predicts a decrease in prices between 2008 and 2012. This decrease in prices
produces a pronounced dip in the shape of the forecast as shown on the graph on Attachment 1.
In its Petition, Idaho Power points out that there is an extreme divergence between
NWPCC's new forecast of natural gas prices and the natural gas prices used in the avoided cost
calculation model. This extreme divergence is illustrated in Attachment 1. Using the adopted
method, the fuel prices used in the avoided cost model exceed the prices in the Council's actual
gas price forecast in all but one year of the forecast. The current methodology, while it fairly
replicated gas price forecasts in the past where prices were always increasing, now fails to
STAFF COMMENTS OCTOBER 23 2007
recognize the expected downward trend in fuel prices apparent in NWPCC's 20-year forecast.
Failing to recognize the downward price trend in the NWPCC's 2007 forecast will cause the
published rates to be much higher than they otherwise would be.
Staff notes that it is very important that the fuel cost component of the avoided cost rates
be accurately modeled. The fuel cost component in the SAR methodology comprises
approximately two-thirds of the avoided cost rates.
Idaho Power proposes that the Commission utilize the average of all 20 years of the
NWPCC's final 2007 median 20-year natural price forecast as the fuel cost component in the
SAR methodology. Because Idaho Power proposes to use the 20-year average price, no
escalation forecast is needed.
Staff is convinced that the current methodology for computing the fuel component of the
published avoided rates poorly replicates gas forecasts shaped like the Council's 2007 forecast.
However, Staff does not agree with Idaho Power s proposal to average all 20 years of the
forecast. The Company s proposed approach cannot accurately replicate the shape of any
forecast, it fails to recognize the time value of money, and it could in the future produce even
more divergence between forecasted and modeled gas prices than the current method.
A much better approach, Staff contends, is to simply use each year of the Council'
entire forecast "as-. This approach is straightforward, simple and mathematically sound. It
eliminates problems that occur when trying to replicate a forecast with computed numbers. It
recognizes the time value of money and will work equally well in the future with forecasts of any
shape.
The table below depicts four sets of published avoided cost rates for Idaho Power for the
years 2007-2009:
(1) the current published avoided cost rates;
(2) the published avoided cost rates that would go into effect if the 2007 NWPCC natural gas
price forecast is used and the 3-year average natural gas price method remains
unchanged;
(3) the Idaho Power proposal- the fuel cost component is computed using the average of the
20 years of natural gas prices from the NWPCC's 2007 median gas price forecast, and
(4) Staffs proposal to use each year of the Council's entire forecast.

2009 65.74.68.67.
Because the same methodology is used to compute the avoided cost rates for Idaho
Power, A vista and PacifiCorp, any change in methodology approved by the Commission in this
case should apply to all three utilities. Using Staffs proposed methodology and the Council'
new forecast, avoided cost rates for each of the three utilities for the years 2007-2009 would be
as shown in the table below:
20-yr Levelized Avoided Cost Rate

On-line Date Idaho Power Avista PacifiCorp
2007 66.67.67.
2008 67.67.67.
2009 67.68.68.
Staff believes its proposed approach is fair and reasonable, but it does suffer from one
minor problem. The Council's forecast, while commonly referred to as a 20-year forecast
actually extends to 2030. That provides Staff with 24 years of forecasted gas prices (including
2007) with which to use in computing avoided cost rates. Staff has traditionally produced tables
showing avoided cost rates for projects scheduled to come online up to five years in the future
(See Attachment 2). Thus, 25 years of forecasted prices are needed in order to produce 20-year
contract rates for projects coming online five years from now. On Attachment 2, for example, a
20-year levelized rate for a project that comes online in 2012 cannot be computed with a gas
forecast that only extends to 2030. Similarly on Attachment 2, non-Ievelized rates for years
STAFF COMMENTS OCTOBER 23,2007
beyond 2030 also cannot be computed. (See the circled figures on Attachment 2). This problem
will propagate one year at a time until the NWPCC renews and extends its forecast so that 25
years of forecasted prices are available.
To resolve this problem, Staff proposes to extend the natural gas price forecast by the
necessary years using a mathematical extrapolation. An exponential growth function is used in
the avoided cost spreadsheet to compute gas prices based on the last ten years of the NWPCC
forecast.
Staff believes that this method produces reasonable results because any possible errors in
the approximation technique are likely extremely small considering the overall forecast accuracy.
Furthermore, it is uncommon for contracts to be written for projects not expected to come online
five years into the future, thus, it is unlikely that approximated avoided cost rates would need to
be used anyway.
A complete set of fueled and non-fueled rates for each utility computed using the new
NWPCC fuel price forecast and the methodology described in these comments is attached as
Attachment 3. Also included for reference purposes, as Attachment 4 , is a printout of the revised
avoided cost spreadsheet. Electronic copies of the spreadsheet have been provided to each of the
utilities, and are available upon request to any 'other interested party.
ST AFF RECOMMENDATIONS
Staff recommends the following:
1) That the Commission adopt the September 2007 fuel price forecast of the Northwest
Power and Conservation Council for use in computing published avoided cost rates;
2) That the Commission issue an Order changing the method for determining the fuel cost
component of the SAR methodology to utilize each of the 20 years set out in the
NWPCC's 2007 median forecast of natural gas prices rather than the escalated average of
the first 3 years of the same forecast, and
3) That the rates computed using the September 2007 Council forecast and the new
proposed fuel cost methodology be effective beginning November 2007.
