FROM:SCOTT WOODBURY
DATE:NOVEMBER 26, 2003
RE:CASE NOS. A VU-03-8, IPC-03-, PAC-03-
AVOIDED COST-VARIABLE RATE
REVISED FUEL PRICE (NATURAL GAS)
The Idaho Public Utilities Commission in Order No. 29124, Case No. GNR-02-
ordered several changes to the variables and manner in which avoided cost rates are to be
computed for projects smaller than 10 MW. Among the ordered changes were abandonment of
the utility first deficit year, changes in cost variables associated with a combined cycle
combustion turbine and changes in the manner in which fuel costs are determined.
More specifically for fuel costs, the Commission chose to adopt the medium fuel
pnce forecast prepared by the Northwest Power and Conservation Council (formerly the
Northwest Power Planning Council) along with the method for establishing the starting year gas
price and escalation rate proposed by the Idaho Independent Energy Producer s witness Trippel.
Order No. 29124 states that natural gas prices can be updated when a new Northwest Power and
Conservation Council forecast becomes available.
A new fuel price forecast was prepared by the Council on April 22, 2003. Staff has
used this forecast to compute new avoided cost rates for proj ects smaller than 10 MW according
to the revised methodology spelled out in Order No. 29124. A copy of the revised fuel price
forecast, computation of starting year gas price and escalation rate, and Staff computation of the
resultant avoided cost rates was provided to PacifiCorp, Idaho Power and Avista for their review.
All utilities by letter accept the calculated rate schedules as accurate.
DECISION MEMORANDUM
Under the revised fuel price forecast of the Northwest Power & Conservation
Council, the starting gas price increases from $3.75/mmbtu to $4.40/mmbtu; the fuel escalation
rate decreases from 2.6% to 2.4%.
Commission Decision
Pursuant to Commission approved avoided cost methodology (Order No. 29124)
natural gas prices are to be updated when a new Northwest Power & Conservation Council
forecast becomes available. The medium fuel price forecast prepared by the Northwest Power &
Conservation Council has changed. The resultant change in avoided cost rates is a simple
arithmetic calculation. The new forecast includes a new starting gas price and fuel escalation
rate. Staff recommends that the Commission approve the Staff calculated changes in the avoided
cost rates for Idaho Power, Avista and PacifiCorp (see attached) for an effective date of
December 15 , 2003.
