BEFORE THE IDAHO PUBLIC UTILITIES COMMISSION
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
ERRATA TO
ORDER NO. 30480
CASE NO. IPC-07-
The Commission Staff has discovered an error in one of the generic input variables
used to compute the avoided cost rates contained in Order No. 30480, issued on December 28
2007.
In Order No. 30480 the Commission adopted the September 11 , 2007 natural gas
price forecast of the Northwest Power and Conservation Council (NWPCC), and modified the
method used to incorporate the gas price forecast such that all years of the forecast are used "
is." The natural gas prices provided in the Council's forecast are real prices, but nominal prices
are needed for the avoided cost computations. A general inflation rate is used in the avoided cost
spreadsheet to convert the forecast prices from real to nominal. A general inflation rate of 2.
was accepted by the Commission in the underlying methodology (Case No. GNR-02-, Order
No. 29124, p. 12), consequently, the same general inflation rate should have been used to derive
the rates in Order No. 30480. Instead, a general inflation rate of 2.1 % was erroneously used.
Attached to this Erratum are corrected avoided cost rates that replace the rates
contained in Order No. 30480.
ERRATA TO ORDER NO. 30480
DONE by Order ofthe Idaho Public Utilities Commission at Boise, Idaho this /3#

EFFECTIVE DATE ADJUSTABLE COMPONENT

The total avoided cost rate in each year is the sum of the adjustable component and the fixed component from either of the tables
above.
Example 1. A 20-year levelized contract with a 2008 on-line date would receive the following rates:
Years Rate
17.99 + 52.
17.99 + Adjustable component in each year
Example 2. A 4-year non-Ievelized contract with a 2008 on-line date would receive the following rates:
Years Rate
15.33 + 52.
15.68 + Adjustable component in year 2009
16.04 + Adjustable component in year 2010
16.41 + Adjustable component in year 2011
