Monsanto Data Request 2.7
Monsanto Data Request 2.7
Please explain how STP transmission capability and expense were modeled in
GRID and provide all supporting workpapers.
Response to Monsanto Data Request 2.7
STP transmission capabilty is based on the average capacity over each path in the
48 months ending December 2009. Only paths that averaged more than one
megawatt of capacity are included. Please refer to Confidential Attchment
Monsanto 2.7 for the workpaper supporting the modeled STP transmission
capacities.
There is no incremental expense associated with the use of STP transmission
with the GRID modeL. The Company's wheeling expenses are based on the
twelve months ending December 2009, with known and measurable changes.
Please refer to Confidential Attchment Monsanto 2.10 -10 for the workpaper
supporting wheeling expenses.
Confdential information is provided subject to the terms and conditions of the

Please provide an explanation and provide supporting workpapers of each

Response to Monsanto Data Request 2.33
The Company objects to this request on the grounds that it is unduly burdensome.
Without waiving this objection, the Company states the following:
Since the filing, the Company has identified the following corrections:
. Dunlap was modeled without reserve requirements
. STPtransmission from southeast Idaho to nortern Utah was not removed
afer the inclusion of the Populus to Terminal addition
. The UAMPS Use of Facilities wheeling expense should have been
excluded.
The in-service date of the Top of the World contract has changed from
November i, 2010 to October 1, 2010. The Company has also received
information on changes to the existing contracts and addition of new contracts.
The Company has not performed a study on how these changes would impact net
power costs in the curent proceeding.
Prior to its rebuttal, the Company anticipates additional chages to various
components of the net power costs, including but not limited to the new Official
Forward Price Cure and new short term firm electricity and natual gas
transactions.

Plant operating parameters periodically change due to a variety of reasons. The
changes from the previous case to the current case can be sumarized into three
broad categories: controls upgrades due to new technologies; performance test
upgrades after major equipment overhauls durng a planed outage; and
corrections of past operating parameters by the plant operators at plants where
PacifiCorp is a minority-share plant owner but not the plant operator. Please refer

Response to Monsanto Data Request 2.59
The Company is not able to track actual wind integration costs. Wind integration
costs include expenses for holding incremental reserves and for balancing the
system as wind deviates from expected generation levels. Operationally, the
Company holds reserves to maitain reliabilty and balances the system in
response to changes in actual system conditions affected by a broad range of
varables. Consequently, it is not feasible to isolate how operations and
associated costs would have changed absent wind.
