Exhibit 245
Page 2 of 2Valuation Of Monsanto Interruptibility
Based on PacifiCorp's Methodology
Explanation of Calculations:
Column (1): PacifiCorp Rebuttal Testimony August 23, 2002
Column (2): Corrected by PacifiCorp in Surrebuttal September 5, 2002
Column (3): Corrected and With Monsanto Adjustments
PacifiCorp Rebuttal Testimony filed August 23, 2002, Exhibit Nos. 13, 14 and 15. Line 46 is
the value of the interruptibility on a "per MWH" basis using Monsanto usage of 1,354,000
MWH as proposed by PacifiCorp in Exhibit No. 11.
At the hearing, PacifiCorp updated its calculation by revising line 4 up to 67 MW, and revising
according to PacifiCorp's proposed rate design. PacifiCorp agreed that Monsanto would not
need to sell 1,000 hours of interruptibility since the second 500 hours were shown to have a
negative value.
Column (3) starts with the corrected Column (2) and represents three adjustments made by
Monsanto to arrive at the net price of $20.67 per MWH. These adjustments include
eliminating lost revenues from the valuation, increasing the FERC Rate Cap to $1,000 per
MWH, and starting with a firm price of $28.3 per MWH.

Valuation Of Monsanto Interruptibility
Based on the Avoided Peaker Resource
Explanation of Calculations:
Column (1): OR WA Simple Cycle CT
Column (2): UTAH Simple Cycle CT
Column (3): OR WA CT, 3 Furnances, 500 Hours Only
Avoided costs based on the resource cost of a simple cycle CT built in Oregon or Washington
according to PacifiCorp's RAMPP-6 planning documents. Both Mr. Schunke and Dr. Rosenberg use
the avoidance of this resource in their valuation of Monsanto's interruptibility. Curtailed capacity and
energy amounts are from Monsanto's original proposal. The curtailed energy of 68,450 MWH was
detailed by Mr. Schunke in his Exhibit 101. Line 20 is the value of the interruptibility on a "per MWH"
basis using Monsanto usage of 1,354,000 MWH as proposed by PacifiCorp in Exhibit No. 11.
The costs for a simple cycle CT built in Utah are also presented in the RAMPP-6 planning documents,
and result in a higher valuation. This resource was used by Mr. Yankel in his testimony, and referenced
by Dr. Rosenberg in his rebuttal. The curtailed capacity and energy amounts are the same as those
shown in Column (1), and are based on Monsanto's original proposal.
Column (3) uses the avoided costs of a CT built in Oregon or Washington, similar to that used in
Column (1). The curtailed capacity and energy amounts reflect Monsanto's updated proposal for
interrupting all three furnaces. The avoided capacity is 162.5 MW before reserves or losses. The
energy curtailed is equal to 800 hours x 162.5 MW, or 130,000 MWH.
