due date to the date of payment unless and until the Executive
Committee shall determine another rate.
9.4 In case any portion of any bill is in dispute, the entire bill
shall be paid when due. Any excess amount of bills which,
through inadvertent errors or as a result of a dispute, may
have been overpaid shall be returned by the owing Party upon
determination of the correct amount, with interest accrued at
the rate of one percent (1%) per month, or the maximum
interest rate permitted by law, if any, whichever is less,
prorated by days from the date of overpayment to the date of
refund unless and until the Executive Committee shall

two (2) years from the date on which the first bill was
delivered for a specific transaction.
9.5 If a Party's records reveal that a bill was not delivered for
a specific transaction, then the Party may deliver to the
appropriate Party a bill within two (2) years from the date on
which the bill would have been delivered under Section 9.1 of
this Agreement. The right to payment is waived with respect to
transactions, or portions thereof, not billed within such two
(2) year period.

shall keep complete and accurate records, and shall maintain
such data as may be necessary for the purpose of ascertaining

Within a two (2) year period from the date the first bill was
delivered under this Agreement, any Party to that transaction
may request in writing copies of the records of the other
Party for that transaction to the extent reasonably necessary
to verify the accuracy of any statement or charge. The Party
from which documents or data has been requested shall
cooperate in providing the documents and data within a
reasonable time period.
10. UNCONTROLLABLE FORCES:
No Party shall be considered to be in breach of this Agreement
or any applicable Confirmation Agreement to the extent that a failure
to perform its obligations under this Agreement or any such
Confirmation Agreement shall be due to an Uncontrollable Force. The
term "Uncontrollable Force" means an event or circumstance which
prevents one Party from performing its obligations under one or more
transactions, which event or circumstance is not within the reasonable
control of, or the result of the negligence of the claiming Party, and
which by the exercise of due diligence, the claiming Party is unable to
avoid, cause to be avoided, or overcome. "Uncontrollable Forces" may
include and are not restricted to flood, drought, earthquake, storm,
fire, lightning, epidemic, war, riot, civil disturbance or
disobedience, labor dispute, labor or material shortage, sabotage,
restraint by court order or public authority, and action or nonaction
by, or failure to obtain the necessary authorizations or approvals
from, any governmental agency or authority

Western Systems Power Pool Original Sheet No. 22A
Rate Schedule FERC No. 6

The following shall not be considered "Uncontrollable Forces": (i)
the price of electricity faced by Seller; or (ii) Purchaser's inability
due to price to use or resell the power purchased hereunder. No Party
shall, however, be relieved of liability for failure of performance to
the extent that such failure is due to causes arising out of its own
negligence or due to removable or remediable causes which it fails to
remove or remedy within a reasonable time period. Nothing contained
herein shall be construed to require a

Western Systems Power Pool First Revised Sheet No. 23
Rate Schedule FERC No. 6 Superseding Original Sheet No. 23

Party to settle any strike or labor dispute in which it may be
involved. Any Party rendered unable to fulfill any of its obligations
by reason of an Uncontrollable Force shall give prompt notice of such
fact and shall exercise due diligence, as provided above, to remove
such inability within a reasonable time period. If oral notice is
provided, it shall be promptly followed by written notice.
Notwithstanding the "due diligence" obligations or obligations
to remove or remedy the causes set forth in the foregoing paragraph
(which do not apply to this paragraph except as specified below), where
the entity providing transmission services for transactions under any
Service Schedule interrupts such transmission service, the interruption
in transmission service shall be considered an Uncontrollable Force
under this Section 10 only in the following two sets of circumstances:
(1) An interruption in transmission service shall be considered an
Uncontrollable Force if (a) the Parties agreed on a
transmission path for that transaction at the time the
transaction under this Agreement was entered into by the
Parties' thereto, (b) firm transmission involving that
transmission path was obtained pursuant to a transmission
tariff or contract to effectuate the transaction under the
applicable Service Schedule, and (c) the entity providing
transmission service curtailed or interrupted such firm
transmission pursuant to the applicable transmission tariff
or contract;

(2) if the Parties did not agree on the transmission path
for a transaction at the time the transaction was entered
into, an interruption in transmission service shall be

Western Systems Power Pool Original Sheet No. 24
Rate Schedule FERC No. 6

considered an Uncontrollable Force only if (a) the Party
contracting for transmission services shall have made
arrangements with the entity providing transmission service
for firm transmission to effectuate the transaction under the
applicable Service Schedule, (b) the entity providing
transmission service curtailed or interrupted such
transmission service due to an event of Uncontrollable Forces
or provision of like effect, and (c) the Party which
contracted for such firm transmission services could not
obtain alternate energy at the delivery point, alternate
transmission services, or alternate means of delivering energy
after exercising due diligence.
No Party shall be relieved by operation of this Section 10 of
any liability to pay for power delivered to the Purchaser or to make
payments then due or which the Party is obligated to make with respect
to performance which occurred prior to the Uncontrollable Force.
11. WAIVERS:
Any waiver at any time by any Party of its rights with respect
to a default under this Agreement or any Confirmation Agreements, or
any other matter under this Agreement, shall not be deemed a waiver
with respect to any subsequent default of the same or any other matter.
12. NOTICES:
12.1 Except for the oral notice provided for in Section 10 of this
Agreement, any formal notice, demand or request provided for
in this Agreement shall be in

Western Systems Power Pool Original Sheet No. 25
Rate Schedule FERC No. 6

writing and shall be deemed properly served, given or made if
delivered in person, or sent by either registered or certified
mail, postage prepaid, or prepaid telegram or fax or other
means agreed to by the Parties.
12.2 RESERVED
12.3 Notices and requests of a routine nature applicable to
delivery or receipt of power or energy or operation of
facilities shall be given in such manner as the committees
from time to time or the Parties to a transaction shall
prescribe.
13. APPROVALS:
13.1 This Agreement is subject to valid laws, orders, rules and
regulations of duly constituted authorities having
jurisdiction. Nothing contained in this Agreement shall give
FERC jurisdiction over those Parties not otherwise subject to
such jurisdiction or be construed as a grant of jurisdiction
over any Party by any state or federal agency not otherwise
having jurisdiction by law.
13.2 This Agreement, including any Service Schedule hereto, shall
become effective as to any Party when it is accepted for
filing by FERC, without changes or conditions unacceptable to
such Party, for application to the Parties subject to FERC
jurisdiction under the Federal Power Act; provided, however,
that nothing in this Agreement is intended to restrict the
authority of the Bonneville Power Administration (BPA)
pursuant to applicable statutory authority to use its existing
wholesale power and transmission rates or to adopt new rates,
rate schedules, or general rate schedule provisions for
application under this Agreement and obtain

Western Systems Power Pool Original Sheet No. 26
Rate Schedule FERC No. 6

interim or final approval of those rates from FERC pursuant to
Section 7 of the Pacific Northwest Electric Power Planning and
Conservation Act, 16 U.S.C. Sec. 839e, provided such rates do
not exceed the maximum rates in the applicable Service
Schedule and are consistent with the terms and conditions of
said Service Schedule. If, upon filing of this Agreement by
Parties subject to FERC jurisdiction under the Federal Power
Act, FERC orders a hearing to determine whether this Agreement
or a Service Schedule under this Agreement is just and
reasonable under the Federal Power Act, the Agreement or
Service Schedule shall not become effective until the date
when an order issued by FERC, determining this Agreement or
the Service Schedule to be just and reasonable without changes
or new conditions unacceptable to the Parties, is no longer
subject to judicial review. Any changes or conditions imposed
by any agency or court, including FERC ordering a hearing,
shall be cause for immediate withdrawal by any nonconsenting
Party.
13.3 The Parties subject to FERC jurisdiction under the Federal
Power Act shall have the right to terminate their
participation in this Agreement, and any rate schedule or
services included herein, pursuant to the terms of Section 5
of this Agreement and without the necessity of further filing
with or approval by FERC.
13.4 Any amendment or change in maximum rates specified in the
Service Schedules shall not become effective with regard to
any Party that is subject to FERC jurisdiction under the
Federal Power Act until it is accepted for filing or

Western Systems Power Pool Original Sheet No. 27
Rate Schedule FERC No. 6

confirmed and approved by FERC as specified in and subject to
the conditions of Section 13.2.
13.5 Nothing contained in this Agreement shall be construed to
establish any precedent for any other agreement or to grant
any rights to or impose any obligations on any Party beyond
the scope and term of this Agreement.
14. TRANSFER OF INTEREST IN AGREEMENT:
No Party shall voluntarily transfer its membership under this
Agreement without the written consent and approval of all other Parties
except to a successor in operation of the applicable properties of such
Party. With regard to the transfer of the rights and obligations of any
Party associated with transactions under the Service Schedules, neither
Party may assign such rights or obligations unless (a) the other Party
provides its prior written consent which shall not be unreasonably
withheld; or (b) the assignment is to a successor in operation whose
creditworthiness is comparable to or higher than that of the assigning
Party. Any successor or assignee of the rights of any Party, whether by
voluntary transfer, judicial or foreclosure sale or otherwise, shall be
subject to all the provisions and conditions of this Agreement and
Confirmation Agreements (where applicable) to the same extent as though
such successor or assignee were the original Party under this Agreement
or the Confirmation Agreements, and no assignment or transfer of any
rights under this Agreement or any Confirmation Agreement shall be
effective unless and until the assignee or transferee agrees in writing
to assume all of the obligations of the assignor or transferor and to
be bound by all of the provisions and

Western Systems Power Pool First Revised Sheet No. 28
Rate Schedule FERC No. 6 Superseding Original Sheet No. 28

conditions of this Agreement and any Confirmation Agreement (where
applicable). The execution of a mortgage or trust deed or a judicial or
foreclosure sale made thereunder shall not be deemed a voluntary
transfer within the meaning of this Section 14.
15. SEVERABILITY:
In the event that any of the terms, covenants or conditions of
this Agreement or any Confirmation Agreement, or the application of any
such term, covenant or condition, shall be held invalid as to any
person or circumstance by any court, regulatory agency, or other
regulatory body having jurisdiction, all other terms, covenants or
conditions of this Agreement and the Confirmation Agreement and their
application shall not be affected thereby, but shall remain in force
and effect unless a court, regulatory agency, or other regulatory body
holds that the provisions are not separable from all other provisions
of this Agreement or such Confirmation Agreement.
16. MEMBERSHIP:
16.1 Any Electric Utility, Retail Entity or Qualifying Facility may
become a Party to this Agreement. The Executive Committee
shall notify such Electric Utility, Retail Entity or
Qualifying Facility of its decision within sixty (60) days of
a request to become a Party to this Agreement, and any
acceptable entity shall become a Party hereto by the execution
of this Agreement or a counterpart hereof, payment of costs
pursuant to Section 16.4, and concluding any necessary
acceptance or approval referred to in Section 13. Any such
Party, if it is subject to the ratemaking jurisdiction of
FERC,

shall be responsible for any FERC filing necessary for it to
implement its performance under this Agreement.
16.2 Each Party shall continue to meet the requirements of
Section 16.1 in order to remain a Party to this Agreement
16.3 Being a Party to this Agreement shall not serve as a
substitute for contractual arrangements that may be needed
between any Party which operates a Control Area and any other
Party which operates within that Control Area.
16.4 Any entity that becomes a Party to this Agreement which was
not a party to the experimental Western Systems Power Pool
Agreement shall pay a one time fee of $25,000 under this
Agreement in recognition of prior efforts and costs incurred
by the parties to the experimental Western Systems Power Pool
Agreement, which efforts greatly facilitated development of
this Agreement. Such fee shall be credited to future costs of
the Operating Agent incurred hereunder.
17. RELATIONSHIP OF PARTIES:
17.1 Nothing contained herein or in any Confirmation Agreement
shall be construed to create an association, joint venture,
trust, or partnership, or impose a trust or partnership
covenant, obligation, or liability on or with regard to any
one or more of the Parties. Each Party shall be individually
responsible for its own covenants, obligations, and
liabilities under this Agreement and under any applicable
Confirmation Agreement.

17.2 All rights of the Parties are several, not joint. No Party
shall be under the control of or shall be deemed to control
another Party. Except as expressly provided in this Agreement,
no Party shall have a right or power to bind another Party
without its express written consent.
18. NO DEDICATION OF FACILITIES:
Any undertaking by one Party to another Party under any
provision of this Agreement shall not constitute the dedication of the
electric system or any portion thereof of the undertaking Party to the
public or to the other Party, and it is understood and agreed that any
such undertaking under any provision of this Agreement by a Party shall
cease upon the termination of such Party's obligations under this
Agreement.

or obligate any Party to provide any services hereunder directly to or
for retail customers of any Party.

or revenues, personal injury, or any other direct, indirect,
or consequential damages or injury, or punitive damages, which
may occur or result from the performance or non-performance of
this Agreement (including any applicable Confirmation
Agreement), including any negligence arising hereunder. Any
liability or damages faced by an officer or employee of a
Federal agency or by that agency that would result from the
operation of this provision shall not be inconsistent with
Federal law.
21.2 [RESERVED]
21.3 The following damages provision shall apply to transactions
under Service Schedules B and C. For transactions under
Service Schedule A, this damages provision or some other
damages provision will apply only if such a damages provision
is agreed to through a Confirmation Agreement. The damages
under this Section 21.3 apply to a Party's failure to deliver
or receive electric power or energy in violation of the terms
of the Agreement and any Confirmation Agreement. The Contract
Quantity and Contract Price referred to in this Section 21.3
are part of the agreement between the Parties for which
damages are being calculated under this Section.
(a) If either Party fails to deliver or receive, as the
case may be, the quantities of electric power or
energy due under the Agreement and any Confirmation
Agreement (thereby becoming a "Non-Performing Party"
for the purposes of this Section 21.3), the other
party (the "Performing

Western Systems Power Pool Original Sheet No. 32
Rate Schedule FERC No. 6

Party") shall be entitled to receive from the
Non-Performing Party an amount calculated as follows
(unless performance is excused by Uncontrollable
Forces as provided in Section 10, the applicable
Service Schedule, or by the Performing Party): (1) If
the amount the Purchaser scheduled or received in any
hour is less than the
applicable hourly Contract Quantity, then
the Purchaser shall be liable for (a) the
product of the amount (whether positive or
negative), if any, by which the Contract
Price differed from the Sales Price
(Contract Price - Sales Price) and the
amount by which the quantity received by the
Purchaser was less than the hourly Contract
Quantity; plus (b) the amount of
transmission charge(s), if any, for firm
transmission service upstream of the
delivery point, which the Seller incurred to
achieve the Sales Price, less the reduction,
if any, in transmission charge(s) achieved
as a result of the reduction in the
Purchaser's schedule or receipt of electric
energy (based on Seller's reasonable
commercial efforts to achieve such
reduction). If the total amounts for all
hours calculated under this paragraph (1)
are negative, then neither the Purchaser nor
the Seller shall pay any amount under this
Section 21.3(a)(1).

Western Systems Power Pool Original Sheet No. 33
Rate Schedule FERC No. 6

(2) If the amount the Seller scheduled or
delivered in any hour is less than the
applicable hourly Contract Quantity, then
the Seller shall be liable for (a) the
product of the amount (whether positive or
negative), if any, by which the Replacement
Price differed from the Contract Price
(Replacement Price - Contract Price) and the
amount by which the quantity delivered by
the Seller was less than the hourly Contract
Quantity; plus (b) the amount of
transmission charge(s), if any, for firm
transmission service downstream of the
delivery point, which the Purchaser incurred
to achieve the Replacement Price, less the
reduction, if any, in transmission charge(s)
achieved as a result of the reduction in the
Seller's schedule or delivery (based on
Purchaser's reasonable commercial effort to
achieve such reduction). If the total
amounts for all hours calculated under this
paragraph (2) are negative, then neither the
Purchaser nor the Seller shall pay any
amount under this Section 21.3(a)(2).
(3) The Non-Performing Party shall pay any
amount due from it under this section within
the billing period as specified in Section 9
of this Agreement or agreed to in the
applicable Confirmation Agreement if the
Parties agreed to revise the billing period
in Section 9.

Western Systems Power Pool Original Sheet No. 34
Rate Schedule FERC No. 6

(b) The Parties agree that the amounts recoverable under
this Section 21.3 are a reasonable estimate of loss
and not a penalty, and represent the sole and
exclusive remedy for the Performing Party. Such
amounts are payable for the loss of bargain and the
loss of protection against future risks.
(c) Each Party agrees that it has a duty to mitigate
damages in a commercially reasonable manner to
minimize any damages it may incur as a result of the
other Party's performance or non-performance of this
Agreement.
(d) In the event the Non-Performing Party disputes the
calculation of the damages under this Section 21.3,
the Non-Performing Party shall pay the full amount
of the damages as required by Section 9 of this
Agreement to the Performing Party. After informal
dispute resolution as required by Section 34.1, any
remaining dispute involving the calculation of the
damages shall be referred to binding dispute
resolution as provided by Section 34.2 of this
Agreement. If resolution or agreement results in
refunds or the need for refunds to the
Non-Performing Party, such refunds shall be
calculated in accordance with Section 9.4 of this
Agreement.
22. DEFAULT OF TRANSACTIONS UNDER THIS AGREEMENT AND CONFIRMATION
AGREEMENTS:

22.1 EVENTS OF DEFAULT
An "Event of Default" shall mean with respect to a Party
("Defaulting Party"):

Western Systems Power Pool First Revised Sheet No. 35
Rate Schedule FERC No. 6 Superseding Original Sheet No. 35

(a) the failure by the Defaulting Party to make, when
due, any payment required pursuant to this Agreement
or Confirmation Agreement if such failure is not
remedied within two (2) Business Days after written
notice of such failure is given to the Defaulting
Party by the other Party ("the Non-Defaulting
Party"). The Non-Defaulting Party shall provide the
notice by facsimile to the designated contact person
for the Defaulting Party and also shall send the
notice by overnight delivery to such contact person;
or
(b) the failure by the Defaulting Party to provide clear
and good title as required by Section 33.3, or to
have made accurate representations and warranties as
required by Section 37 and such failure is not cured
within five (5) Business Days after written notice
thereof to the Defaulting Party; or
(c) The institution, with respect to the Defaulting
Party, by the Defaulting Party or by another person
or entity of a bankruptcy, reorganization,
moratorium, liquidation or similar insolvency
proceeding or other relief under any bankruptcy or
insolvency law affecting creditor's rights or a
petition is presented or instituted for its
winding-up or liquidation; or
(d) The failure by the Defaulting Party to provide
adequate assurances of its ability to perform all of
its outstanding material obligations to the
Non-Defaulting Party under the Agreement or
Confirmation Agreement

Western Systems Power Pool First Revised Sheet No. 36

pursuant to Section 27 of this Agreement or any
substitute or modified provision in the Confirmation
Agreement.
(e) With respect to its Guarantor, if any:
(i) if a material representation or warranty
made by a Guarantor in connection with this
Agreement, or any transaction entered into
hereunder, is false or misleading in any
material respect when made or when deemed
made or repeated; or
(ii) the failure of a Guarantor to make any
payment required or to perform any other
material covenant or obligation in any
guarantee made in connection with this
Agreement, including any transaction entered
into hereunder, and such failure shall not
be remedied within three (3) Business Days
after written notice; or
(iii) a Guarantor becomes Bankrupt;
(iv) the failure, without written consent of the
other Party, of a Guarantor's guarantee to
be in full force and effect for purposes of
this Agreement (other than in accordance
with its terms) prior to the satisfaction of
all obligations of such Party under each
transaction to which such guarantee shall
relate; or
(v) a Guarantor shall repudiate, disaffirm,
disclaim, or reject, in whole or in part,
or challenge the validity of, any guarantee.

Rate Schedule FERC No. 6

22.2 REMEDIES FOR EVENTS OF DEFAULT
If an Event of Default occurs, the Non-Defaulting
Party shall possess the right to terminate all transactions
between the Parties under this Agreement upon written notice
(by facsimile or other reasonable means) to the Defaulting
Party, such notice of termination to be effective immediately
upon receipt. If the Non-Defaulting Party fails to exercise
this right of termination within thirty (30) days following
the time when the Event of Default becomes known (or more than
thirty days if the Non-Defaulting and Defaulting Parties agree
to an extension), then such right of termination shall no
longer be available to the Non-Defaulting Party as a remedy
for the Event(s) of Default. The Non-Defaulting Party
terminating transaction(s) under this Section 22.2 may do so
without making a filing at FERC.
Upon termination, the Non-Defaulting Party shall
liquidate all transactions as soon as practicable, provided
that in no event will the Non-Defaulting Party be allowed to
liquidate Service Schedule A transactions. The payment
associated with termination ("Termination Payment") shall be
calculated in accordance with this Section 22.2 and Section
22.3. The Termination Payment shall be the sole and exclusive
remedy for the Non-Defaulting Party for each terminated
transaction ("Terminated Transaction") for the time period
beginning at the time notice of termination under this Section
22 is received. Prior to receipt

Western Systems Power Pool
Issued on: May 2, 2001

Western Systems Power Pool Original Sheet No. 37
Rate Schedule FERC No. 6

of such notice of termination by the Defaulting Party, the
Non-Defaulting Party may exercise any remedies available to it
under Section 21.3 of this Agreement or Confirmation
Agreement(s), and any other remedies available to it at law or
otherwise.
Upon termination, the Non-Defaulting Party may
withhold any payments it owes the Defaulting Party for any
obligations incurred prior to termination under this Agreement
or Confirmation Agreement(s) until the Defaulting Party pays
the Termination Payment to the Non-Defaulting Party. The
Non-Defaulting Party shall possess the right to set-off the
amount due it under this Section 22 by any such payments due
the Defaulting Party as provided in Section 22.3(d).
22.3 LIQUIDATION CALCULATION OPTIONS
The Non-Defaulting Party shall calculate the
Termination Payment as follows:
(a) The Gains and Losses shall be determined by
comparing the value of the remaining term,
transaction quantities, and transaction prices under
each Terminated Transaction had it not been
terminated to the equivalent quantities and relevant
market prices for the remaining term either quoted by
a bona fide third-party offer or which are reasonably
expected to be available in the market under a
replacement contract for each Terminated Transaction.
To ascertain the market prices of a replacement
contract, the Non-Defaulting Party may consider,
among other valuations, quotations

Western Systems Power Pool Original Sheet No. 38
Rate Schedule FERC No. 6

from leading dealers in energy contracts, any or all
of the settlement prices of the NYMEX power futures
contracts (or NYMEX power options contracts in the
case of Physically-Settled Options) and other bona
fide third party offers, all adjusted for the length
of the remaining term and differences in
transmission. It is expressly agreed that the
Non-Defaulting Party shall not be required to enter
into replacement transactions in order to determine
the Termination Payment.
(b) The Gains and Losses calculated under paragraph
(a) shall be discounted to present value using the
Present Value Rate as of the time of termination (to
take account to the period between the time notice
of termination was effective and when such amount
would have otherwise been due pursuant to the
relevant transaction). The "Present Value Rate"
shall mean the sum of 0.50% plus the yield reported
on page "USD" of the Bloomberg Financial Markets
Services Screen (or, if not available, any other
nationally recognized trading screen reporting
on-line intraday trading in United States government
securities) at 11:00 a.m. (New York City, New York
time) for the United States government securities
having a maturity that matches the average remaining
term of the Terminated Transactions; and
(c) The Non-Defaulting Party shall set off or
aggregate, as appropriate, the Gains and Losses
(as calculated in Section 22.3(a)) and Costs and
notify

Western Systems Power Pool Original Sheet No. 39
Rate Schedule FERC No. 6

the Defaulting Party. If the Non-Defaulting Party's
aggregate Losses and Costs exceed its aggregate
Gains, the Defaulting Party shall, within three (3)
Business Days of receipt of such notice, pay the
Termination Payment to the Non-Defaulting Party,
which amount shall bear interest at the Present Value
rate from the time notice of termination was received
until paid. If the Non-Defaulting Party's aggregate
Gains exceed its aggregate Losses and Costs, the
Non-Defaulting Party, after any set-off as provided
in paragraph (d), shall pay the remaining amount to
the Defaulting Party within three (3) Business Days
of the date notice of termination was received
including interest at the Present Value from the time
notice of termination was received until the
Defaulting Party receives payment.
(d) The Non-Defaulting Party shall aggregate or set off,
as appropriate, at its election, any or all other
amounts owing between the Parties (discounted at the
Present Value Rate) under this Agreement and any
Confirmation Agreements against the Termination
Payment so that all such amounts are aggregated
and/or netted to a single liquidated amount. The net
amount due from any such liquidation shall be paid
within three (3) Business Days following the date
notice of termination is received.
If the Defaulting Party disagrees with the
calculation of the Termination Payment and the Parties cannot
otherwise resolve their differences, the calculation issue
shall be submitted to informal dispute resolution as provided
in Section 34.1

Western Systems Power Pool Original Sheet No. 40

of this Agreement and thereafter binding dispute resolution
pursuant to Section 34.2 if the informal dispute resolution
does not succeed in resolving the dispute. Pending resolution
of the dispute, the Defaulting Party shall pay the full amount
of the Termination Payment calculated by the Non-Defaulting
Party within three (3) Business Days of receipt of notice as
set forth in Section 33.2(c) subject to the Non-Defaulting
Party refunding, with interest, pursuant to Section 9.4, any
amounts determined to have been overpaid.
For purposes of this Section 22.3:
(i) "Gains" means the economic benefit (exclusive of
Costs), if any, resulting from the termination of the
Terminated Transactions, determined in a commercially
reasonable manner as calculated in accordance with
this Section 22.3;
(ii) "Losses" means the economic loss (exclusive of
Costs), if any, resulting from the termination of the
Terminated Transactions, determined in a commercially
reasonable manner as calculated in accordance with
this Section 22.3;
(iii) "Costs" means brokerage fees, commissions and other
similar transaction costs and expenses reasonably
incurred in terminating any specifically related
arrangements which replace a Terminated Transaction,
transmission and ancillary service costs associated
with Terminated Transactions, and reasonable
attorneys' fees, if any, incurred in connection

with the Non-Defaulting Party enforcing its rights
with regard to the Terminated Transactions. The
Non-Defaulting Party shall use reasonable efforts to
mitigate or eliminate these Costs.
(iv) In no event, however, shall a Party's Gains, Losses
or Costs include any penalties or similar charges
imposed by the Non-Defaulting Party.
22A. DEFAULT IN PAYMENT OF WSPP OPERATING COSTS:
22A.1 A Party shall be deemed to be in default in
payment of its share of WSPP operating costs
pursuant to Section 7 of this Agreement, if any,
when payment is not received within ten (10) days
after receipt of written notice. A default by any
Party in such payment obligations shall be cured by
payment of all overdue amounts together with
interest accrued at the rate of one percent (1%) per
month, or the maximum interest rate permitted by
law, if any, whichever is less, prorated by days
from the due date to the date the payment curing the
default is made unless and until the Executive
Committee shall determine another rate.
22A.2 A defaulting Party, which is in default under Section
22.A1, shall be liable for all costs, including costs
of collection and reasonable attorney fees, plus
interest as provided in Section 22.A1 hereof.
22A.3 The rights under this Agreement of a Party which is
in default of its obligation to pay operating costs
under this Agreement for a period of three (3) months
or more may be revoked by a vote of the
non-defaulting

Western Systems Power Pool Original Sheet No. 42
Rate Schedule FERC No. 6

Parties' representatives on the Executive Committee
consistent with Section 8.3. The defaulting Party's
rights shall not be revoked, however, unless said
Party has received at least thirty (30) days written
notice of the non-defaulting Parties' intent to
revoke such rights. Said notice shall state the date
on which the revocation of rights shall become
effective if the default is not cured and shall state
all actions which must be taken or amounts which must
be paid to cure the default. This provision allowing
the non-defaulting Parties to revoke such rights is
in addition to any other remedies provided in this
Agreement or at law and shall in no way limit the
non-defaulting Parties' ability to seek judicial
enforcement of the defaulting Party's obligations to
pay its share of the operating costs under this
Agreement. Upon the effective date of such revocation
of rights, the defaulting party shall not be allowed
to enter into any new transactions under this
Agreement. The defaulting party under the Agreement
or any Confirmation Agreements shall be required to
carry out all obligations that existed prior to the
effective date of such revocation. If a defaulting
Party's rights under this Agreement have been
revoked, the Executive Committee may restore that
Party's rights upon the defaulting Party paying all
amounts due and owing under this Agreement.
22A.4 Upon revocation of the rights of a defaulting Party
under this Agreement, Operating Agent costs hereunder
shall be equally shared among the

Western Systems Power Pool Original Sheet No. 43
Rate Schedule FERC No. 6

remaining Parties. Cost allocation adjustments
shall be retroactive to the date of the default.
23. OTHER AGREEMENTS:
No provision of this Agreement shall preclude any Party from
entering into other agreements or conducting transactions under
existing agreements with other Parties or third parties. This Agreement
shall not be deemed to modify or change any rights or obligations under
any prior contracts or agreements between or among any of the Parties.
24. GOVERNING LAW:
This Agreement and any Confirmation Agreement shall be
governed by and construed in accordance with the laws of the State of
Utah, without regard to the conflicts of laws rules thereof. The
foregoing notwithstanding, (1) if both the Seller and Purchaser are
organized under the laws of Canada, then the laws of the province of
the Seller shall govern, or (2) if the Seller is an agency of or part
of the United States Government, then the laws of the United States of
America shall govern.
25. JUDGMENTS AND DETERMINATIONS:
Whenever it is provided in this Agreement that a Party shall
be the sole judge of whether, to what extent, or under what conditions
it will provide a given service, its exercise of its judgment shall be
final and not subject to challenge. Whenever it is provided that (i) a
service under a given transaction may be curtailed under certain
conditions or circumstances, the existence of which are determined by
or in the judgment of a Party, or (ii) the existence of qualifications
for membership shall be determined by

Western Systems Power Pool Original Sheet No. 44
Rate Schedule FERC No. 6

the Executive Committee pursuant to Section 16, that Party's or the
Executive Committee's determination or exercise of judgment shall be
final and not subject to challenge if it is made in good faith and not
made arbitrarily or capriciously.
26. COMPLETE AGREEMENT:
This Agreement and any subsequent amendments, including the
Service Schedules and Exhibits incorporated herein, and any
Confirmation Agreement, shall constitute the full and complete
agreement of the Parties with respect to the subject matter hereof, and
all prior or contemporaneous representations, statements, negotiations,
understandings and inducements are fully merged and incorporated in
this Agreement.
27. CREDITWORTHINESS:
Should a Party's creditworthiness, financial responsibility,
or performance viability become unsatisfactory to the other Party in
such other Party's reasonably exercised discretion with regard to any
transaction pursuant to this Agreement and any Confirmation Agreement
(after the transaction is agreed to or begins), the dissatisfied Party
(the "First Party") may require the other Party (the "Second Party") to
provide, at the Second Party's option (but subject to the First Party's
acceptance based upon reasonably exercised discretion), either (1) the
posting of a Letter of Credit, (2) a cash prepayment, (3) the posting
of other acceptable collateral or security by the Second Party, (4) a
Guarantee Agreement executed by a creditworthy entity; or (5) some
other mutually agreeable method of satisfying the First Party. The
Second Party's obligations under this Section 27 shall be limited to a
reasonable estimate of the damages to the First Party

Western Systems Power Pool Original Sheet No. 45
Rate Schedule FERC No. 6

(consistent with Section 21.3 of this Agreement) if the Second Party
were to fail to perform its obligations. Events which may trigger the
First Party questioning the Second Party's creditworthiness, financial
responsibility, or performance viability include, but are not limited
to, the following:
(1) The First Party has knowledge that the Second Party (or its
Guarantor if applicable) are failing to perform or defaulting
under other contracts.
(2) The Second Party has exceeded any credit or trading limit set
out in the Confirmation Agreement or other agreement between
the Parties.
(3) The Second Party or its Guarantor has debt which is rated as
investment grade and that debt falls below the investment
grade rating by at least one rating agency or is below
investment grade and the rating of that debt is downgraded
further by at least one rating agency.
(4) Other material adverse changes in the Second Party's financial
condition occur.
(5) Substantial changes in market prices which materially and
adversely impact the Second Party's ability to perform under
this Agreement or any Confirmation Agreement occur.
If the Second Party fails to provide such reasonably
satisfactory assurances of its ability to perform a transaction
hereunder within three (3) Business Days of demand therefore, that will
be considered an Event of Default under Section 22 of this Agreement
and the First Party shall have the right to exercise any of the
remedies provided for under

Western Systems Power Pool First Revised Sheet No. 46
Rate Schedule FERC No. 6 Superseding Original Sheet No. 46

that Section 22. Nothing contained in this Section 27 shall affect any
credit agreement or arrangement, if any, between the Parties.
28. NETTING:
28.1 If the Purchaser and the Seller are each required to pay an
amount to each other in the same calendar month for
transactions under this Agreement, then such amounts with
respect to each Party may be aggregated and the Parties may
discharge their obligations to pay through netting of the
respective amounts due, in which case the Party, if any, owing
the greater aggregate amount may pay to the other Party the
difference between the amounts owed. Each Party reserves to
itself all rights, set-offs, counterclaims, and other remedies
and defenses (to the extent not expressly herein waived or
denied) which such Party has or may be entitled to arising
from or out of this Agreement and any applicable Confirmation
Agreements.
28.2 Parties shall net payments (associated with transactions under
this Agreement and Confirmation Agreement) in accordance with
Exhibit A, if such Parties have executed the form attached as
Exhibit A. The Parties obligation to net shall include the
netting of all payments received by the Parties in the same
calendar month. Parties that have executed Exhibit A shall
provide a signed copy of

Exhibit A to a representative of the WSPP and to any Party
that requests a copy and indicate on the WSPP Homepage that
they have so executed Exhibit A (once the WSPP Homepage
possesses the necessary capability). If a Party indicated its
election to net payments on the WSPP Homepage and that Party
desires to withdraw its agreement to net, that Party shall
provide at least 30 days notice on the WSPP Homepage of the
change in its election to net and also shall provide,
concurrent with its withdrawal notice, written notice to all
Parties with which it has ongoing transactions or with which
it has committed to future transactions under the Agreement at
the time of the notice. Any such changes in netting status
shall apply beginning at least 30 days after notice required
by this Section 28.2 is provided and only shall apply to
transactions agreed to beginning on or after the date the
change in netting status becomes effective.
28.3 The Parties may by separate agreement either through a
Confirmation Agreement or some other agreement set out
specific terms relating to the implementation of the netting
in addition to or in lieu of Exhibit A.

The Contract Price for all transactions under the Service
Schedules shall include full reimbursement for, and the Seller is
liable for and shall pay, or cause to be paid, or reimburse the
Purchaser for if the Purchaser has paid, all taxes applicable to a
transaction that arise prior to the delivery point. If the Purchaser is
required to remit such tax, the amount shall be deducted from any sums

The Contract Price does not include reimbursement for, and the
Purchaser is liable for and shall pay, cause to be paid, or reimburse
the Seller for if the Seller has paid, all taxes applicable to a
transaction arising at and from the delivery point, including any taxes
imposed or collected by a taxing authority with jurisdiction over the
Purchaser. The Purchaser shall indemnify, defend, and hold harmless the
Seller from any claims for such taxes. Either Party, upon written
request of the other Party, shall provide a certificate of exemption or
other reasonably satisfactory evidence of exemption if either Party is
exempt from taxes, and shall use reasonable efforts to obtain and
cooperate with the other Party in obtaining any exemption from or
reduction of any tax. Taxes are any amounts imposed by a taxing
authority associated with the transaction.
30. CONFIDENTIALITY:
The terms of any transaction under the Service Schedules or
any other information exchanged by the Purchaser and Seller relating to
the transaction shall not be disclosed to any person not employed or
retained by the Purchaser or the Seller or their affiliates, except to
the extent disclosure is (1) required by law, (2) reasonably deemed by
the disclosing Party to be required to be disclosed in connection with
a dispute between or among the Parties, or the defense of any
litigation or dispute, (3) otherwise permitted by consent of the other

made pursuant to this provision, the Parties shall use reasonable
efforts to minimize the scope of any disclosure and have the recipients
maintain the confidentiality of any documents or confidential
information covered by this provision, including, if appropriate,
seeking a protective order or similar mechanism in connection with any
disclosure. This provision shall not apply to any information that was
or is hereafter in the public domain (except as a result of a breach of
this provision).
31. TRANSMISSION TARIFF:
Pursuant to FERC Order No. 888, issued on April 24, 1996, and
FERC orders where applicable, the WSPP Default Transmission Tariff has
been filed and has become effective. The Parties agree to be bound by
the terms of that Tariff for so long as they are Western Systems Power
Pool members.

this Agreement may agree to modify any term of this Agreement
which applies to such transaction (but not to provisions
regarding the operation of the WSPP as an organization
including Sections 7 and 8), such agreement to be reflected in
a Confirmation Agreement. Written confirmation shall be
required for all transactions of one week or more. Upon
request of the Purchaser or at the election of the Seller, the
Seller shall provide written confirmation which must be
received by the Purchaser within five Business Days of the
date of the agreement or request. The Purchaser shall have
five Business Days from date of receipt to respond to the
confirmation. If the Purchaser does not respond within that
time period, the Seller's written confirmation shall be
considered as accepted and final except as provided in Section
32.5. If the Seller fails to provide any required written
confirmation within five Business Days, as described above,
then the Purchaser may submit a written confirmation to the
Seller. The Purchaser shall submit such written confirmation
within five Business Days after the deadline for submitting a
written confirmation applicable to the Seller as set forth
above has expired. If the Seller fails to respond to
Purchaser's confirmation within five Business Days, then the
Purchaser's written confirmation shall be considered as
accepted and final except as provided in Section 32.5.
Notwithstanding the foregoing, any failure of the Seller or
the Purchaser to provide written confirmation of the
transaction shall not invalidate any oral agreement of the
Parties. Nor shall any oral agreement of the Parties be
considered invalidated

32.2 The Parties agree not to contest, or assert any defense with
respect to, the validity or enforceability of any agreement to
the terms concerning a specific transaction(s), on the basis
that documentation of such terms fails to comply with the
requirements of any statute that agreements be written or
signed. Each Party consents to the recording by the other
Party, without any further notice, of telephone conversations
between representatives of the Parties, which contain
agreements to or discussion concerning the terms of a specific
transaction(s). All such recordings may be introduced and
admitted into evidence for the purpose of proving agreements
to terms, and any objection to such introduction or admission
for such purpose is hereby expressly waived. The terms
documented hereunder, whether stated in a written document or
a recording, are intended by the Parties as a final expression
of their agreement with respect to such terms as are included
therein and may not be contradicted by evidence of any prior
agreement, but may be supplemented by course of dealing,
performance, usage of trade and evidence of consistent
additional mutually agreed-upon terms.
32.3 For individual transactions under the Service Schedules, the
Agreement as it may be modified or supplemented by a
Confirmation Agreement shall bind the Parties and govern the
transactions; provided, however, if the Parties to a
transaction do not reach agreement on such modification or
change to a term of the Agreement, or the Confirmation
Agreement is not considered accepted and final pursuant to
Section 32.1, then the term or terms of the Agreement, which
the Parties could not

Rate Schedule FERC No. 6 Superseding Original Sheet No. 52

reach agreement to modify or change or which are not
considered modified pursuant to Section 32.1, shall apply to
that transaction. In the event of a conflict between a binding
and effective Confirmation Agreement and this Agreement, the
Confirmation Agreement shall govern.
32.4 The Seller shall not be required to file written confirmations
with FERC except as provided in the Service Schedules.
32.5 When a Confirmation Agreement contains "non-standard
confirmation provisions" which are provisions other than those
set forth in paragraphs (a) 2 (l) of Exhibit C, those
non-standard confirmation provisions shall not be deemed to be
accepted pursuant to Section 32.1 unless agreed to: (i)
orally, with that oral agreement recorded (provided that such
oral agreement option only shall be available for transactions
of less than one week); or (ii) in a writing executed by both
Parties.
32.6 Other Products and Service Levels: The Parties may agree to
use a product/service level defined by a different agreement
(e.g., the California ISO tariff, the ERCOT agreement or the
EEI agreement) for a particular transaction under this
Agreement. Unless the Parties expressly state and agree that
all the terms and conditions of such other agreement will
apply to any such transaction, the transaction shall be
subject to all the terms of this Agreement, except that (1)
all service level/product definitions, (2) force
majeure/uncontrollable force definitions, and (3) other terms
as mutually agreed shall have the meaning

33.3 Warranties
The Seller warrants that it will transfer to the
Purchaser good title to the electric energy sold under the
Agreement and any Confirmation Agreement, free and clear of
all liens, claims, and encumbrances arising or attaching prior
to the delivery point and that Seller's sale is in compliance
with all applicable laws and regulations. THE SELLER HEREBY
DISCLAIMS ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING
ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR
PURPOSE.
34. DISPUTE RESOLUTION:
34.1 INFORMAL DISPUTE RESOLUTION
Before binding dispute resolution or any other form
of litigation may proceed, any dispute between the Parties to
a transaction under this Agreement first shall be referred to
nonbinding mediation. The Parties shall attempt to agree upon
a mediator from a list of ten (10) candidates provided by the
Chairman of the WSPP Operating Committee or his or her
designee. If the Parties are unable to agree, then the
Chairman or the designee shall appoint a mediator for the
dispute. Neither the mediator nor the person involved on
behalf of the WSPP in developing a list of mediators for the
Parties to choose from or in selecting the

Western Systems Power Pool Original Sheet No. 54
Rate Schedule FERC No. 6

mediator (if the Parties are unable to do so) shall possess a
direct or indirect interest in either Party or the subject
matter of the mediation. The WSPP shall establish procedures
for the appointment of mediators and the conduct of mediation
and those procedures shall apply to the mediation.
34.2 BINDING DISPUTE RESOLUTION
The Parties to a dispute may elect binding dispute
resolution using the following process unless binding
arbitration of certain disputes is required under this
Agreement in which event the Parties shall use the process set
forth in this Section 34.2 to resolve such disputes, unless
the Parties otherwise agree:
(a) WSPP Dispute Resolution: A Party to a dispute
(if binding dispute resolution is required) or all
Parties to a dispute (if agreement of the Parties is
required for binding dispute resolution) may
initiate binding dispute resolution under WSPP
procedures by notifying the Chairman of the WSPP
Operating Committee or his or her designee. The
Chairman or his or her designee shall provide the
Parties with a list of ten (10) eligible
arbitrators. Within ten (10) days of receiving the
list, the Parties shall agree on a single arbitrator
from the list to conduct the arbitration, or notify
the Chairman of the Operating Committee or the
designee of their inability to reach agreement. If
notified of the Parties inability to reach
agreement, then the Chairman or the designee shall
choose the arbitrator from the list within five (5)
days. Neither the arbitrator nor the person

Western Systems Power Pool Original Sheet No. 55
Rate Schedule FERC No. 6

involved on behalf of the WSPP in developing a list
of arbitrators for the Parties to choose from or in
selecting the arbitrator (if the Parties are unable
to do so) shall possess a direct or indirect interest
in either Party or the subject matter of the
arbitration. The Procedures to be used for this
arbitration shall follow the arbitration procedures
which shall be developed and maintained by the WSPP
and the procedures will be generally consistent with
the commercial arbitration rules of the American
Arbitration Association though not involving the
Association.
If the Parties agree to binding dispute resolution
under this Section 34.2, each Party understands that it
will not be able to bring a lawsuit concerning any dispute
that may arise which is covered by this arbitration
provision. Notwithstanding the foregoing, nothing herein
is intended to waive any provision of the Federal
Arbitration Act, 9 U.S.C.[sec] 1, et. seq., or any
-- ---
right under state statute or common law to challenge an
arbitration award or to prevent any action to enforce any
arbitration award.
A Party's liability and damages under any arbitration
award resulting from the process set forth in this Section
34.2 shall be limited as provided in this Agreement or in any
Confirmation Agreement.

Western Systems Power Pool Original Sheet No. 56
Rate Schedule FERC No. 6

34.3 COSTS
Each Party shall be responsible for its own costs and
those of its counsel and representatives. The Parties shall
equally divide the costs of the arbitrator or mediator and the
hearing.
34.4 CONFIDENTIALITY
Any arbitration or mediation under this Section 34
shall be conducted on a confidential basis and not disclosed,
including any documents or results which shall be considered
confidential, unless the Parties otherwise agree or such
disclosure is required by law.
35. FORWARD CONTRACTS:
The Parties acknowledge and agree that all transactions under
the Agreement and Confirmation Agreement(s) are forward contracts and
that the Parties are forward contract merchants, as those terms are
used in the United States Bankruptcy Code. The Parties acknowledge and
agree that all of their transactions, together with this Agreement and
the related Confirmation Agreement(s) form a single, integrated
agreement, and agreements and transactions are entered into in reliance
on the fact that the agreements and each transaction form a single
agreement between the Parties.
36. TRADE OPTION EXCEPTION
The Parties intend that any Physically Settled Option under
this Agreement shall qualify under the trade option exception, 17
C.F.R. [sed] 32.4. Accordingly, each Party buying or selling a
Physically Settled Option agrees and warrants that any such option

Western Systems Power Pool Original Sheet No. 57
Rate Schedule FERC No. 6

shall be offered only to a provider, user, or merchant and that the
entities entering into the options are doing so solely for purposes
related to their business.
37. ADDITIONAL REPRESENTATIONS AND WARRANTIES:
Each Party warrants and represents to the other(s) that it
possesses the necessary corporate, governmental and legal authority,
right and power to enter into and agree to the applicable Confirmation
Agreement for a transaction or transactions and to perform each and
every duty imposed, and that the Parties' agreement to buy and sell
power under this Agreement and the Confirmation Agreement represents a
contract. Each Party also warrants and represents to the other(s) that
each of its representatives executing or agreeing through a
Confirmation Agreement to a transaction under this Agreement is
authorized to act on its behalf.
Each Party further warrants and represents that entering into
and performing this Agreement and any applicable Confirmation Agreement
does not violate or conflict with its Charter, By-laws or comparable
constituent document, any law applicable to it, any order or judgment
of any court or other agency of government applicable to it or any
agreement to which it is a party and that this Agreement and applicable
Confirmation Agreement(s), constitute a legal, valid and binding
obligation enforceable against such Party in accordance with the terms
of such agreements.
Each Party also represents that it is solvent and that on each
delivery this representation shall be deemed renewed unless notice to
the contrary is given in writing by the Purchaser to the Seller before
delivery.

38. FLOATING PRICES:
38.1 In the event the Parties intend that the price for a
transaction is to be based on an index, exchange or any other
kind of variable reference price (such price being a "Floating
Price"), the Parties shall specify the "Floating Price" to be
used to calculate the amounts in a Confirmation Agreement due
Seller for that transaction.
38.2 Market Disruption. If a Market Disruption Event has occurred
and is continuing during the Determination Period, the
Floating Price for the affected Trading Day shall be
determined as follows. The Parties shall negotiate in good
faith to agree on a Floating Price (or a method for
determining a Floating Price) for the affected Trading Day. If
the Parties have not so agreed on or before the twelfth
Business Day following the first Trading Day on which the
Market Disruption Event occurred or existed, then the Floating
Price shall be determined in good faith by the Parties based
upon (1) quotes from Dealers in energy contracts; and/or (2)
quotes from Brokers in energy contracts. Each Party may obtain
up to a maximum of four quotes which must be provided to the
other Party no later than twenty-two Business Days following
the first Business Day on which the Market Disruption Event
occurred or existed. These quotes shall reflect transacted
prices. The Floating Price for the affected Trading Day shall
equal a simple average of the quotes obtained and provided by
the Parties consistent with the provisions of this Section 38.
Each Party providing quote(s) to the other Party also shall

A-3.6 The price for Economy Energy Service shall be mutually agreed
to in advance between Seller and Purchaser and shall not be
subject to the rate caps specified in Section A-3.7 in either
of the following two circumstances:
(1) where the Seller is a FERC regulated public utility
and that Seller has been authorized to sell power
like that provided for under this Service Schedule at
market-based rates; or
(2) where the Seller is not a FERC regulated public
utility.
A Party is a FERC regulated public utility if it is a "public
utility" as defined in Section 201(e) of the Federal Power
Act, 16 U.S.C. [sect] 824(e).
A-3.7 Except as provided for in Section A-3.6, the price shall
not exceed the Seller's forecasted Incremental Cost plus up
to: $7.32/kW/ month; $1.68/kW/week;

Western Systems Power Pool Original Sheet No. 80
Rate Schedule FERC No. 6

33.78[cent]/kW/day; 14.07 ▇▇▇▇▇/kWh; or 21.11 ▇▇▇▇▇/kWh for
service of sixteen (16) hours or less per day. The hourly rate
is capped at the Seller's forecasted Incremental Cost plus
33.78[cent] /kW/ day. The total demand charge revenues in any
consecutive seven-day period shall not exceed the product of
the weekly rate and the highest demand experienced on any day
in the seven-day period. In lieu of payment, such Parties may
mutually agree to exchange economy energy at a ratio not to
exceed that ratio provided for in Section C-3.7 of Service
Schedule C. The Seller's forecasted Incremental Cost discussed
above also may include any transmission and/or ancillary
service costs associated with the sale, including the cost of
any transmission and/or ancillary services that the Seller
must take on its own system. Any such transmission and/or
ancillary services charges shall be separately identified by
the Seller to the Purchaser for transactions under this
Schedule including the exchange of economy energy. The
transmission and ancillary service rate ceilings shall be
available through the WSPP's Hub or homepage. Any such
transmission services (and ancillary service provided in
conjunction with such transmission service) by Seller shall be
provided pursuant to any applicable transmission tariff or
agreement, and the rates therefore shall be consistent with
such tariff or agreement.

A-3.8 Unless otherwise agreed, the Purchaser shall be responsible

operating reserve requirements as back-up for Economy Energy
Service purchased and the Seller shall not be required to
maintain such operating reserve.

shall be the sole judge as to the extent to and the conditions
under which it is willing to provide or receive such service

contractual commitments including the Agreement and any
applicable Confirmation Agreement. Once an agreement is
reached, then the obligation for Unit Commitment Service
becomes a firm commitment, for both Parties, for the agreed
capacity and terms.

B-3.2 Unless otherwise mutually agreed by the Parties involved in a
Unit Commitment Service transaction, the terms set forth in
this Service Schedule B shall govern such transaction.

Western Systems Power Pool Original Sheet No. 83
Rate Schedule FERC No. 6

all transactions shall be prescheduled, subject to any
conditions agreed to by schedulers, for a specified unit for a
specified period of time.

B-3.4 Purchasers shall arrange purchases directly with Sellers.

B-3.5 The price for Unit Commitment Service shall be mutually agreed
to in advance between Seller and Purchaser and shall not be
subject to the rate caps specified in Section B-3.6 in either
of the following two circumstances:
(1) where the Seller is a FERC regulated public utility
and that Seller has been authorized to sell power
like that provided for under this Service Schedule at
market-based rates; or
(2) where the Seller is not a FERC regulated public
utility. A Party is a FERC regulated public utility
if it is a "public utility" as defined in Section
201(e) of the Federal Power Act, 16 U.S.C. [sect].
824(e).

B-3.6 Except as provided for in Section B-3.5, the price shall not
exceed the Seller's forecasted Incremental Cost plus up to:
$7.32/kW/month; $1.68/kW/week; 33.78[cent]/kW/day; 14.07
▇▇▇▇▇/kWh; or 21.11 ▇▇▇▇▇/kWh for service of sixteen (16)

Seller's forecasted Incremental Cost plus 33.78[cent]/kW/day.
The total demand charge revenues in any consecutive seven-day
period shall not exceed the product of the weekly rate and the

Western Systems Power Pool Original Sheet No. 84
Rate Schedule FERC No. 6

highest demand experienced on any day in the seven-day period.
The Seller's forecasted Incremental Cost discussed above also
may include any transmission and/or ancillary service costs
associated with the sale, including the cost of any
transmission and/or ancillary services that the Seller must
take on its own system. Any such transmission and/or ancillary
service charges shall be separately identified by the Seller
to the Purchaser. The transmission and ancillary service rate
ceilings shall be available through the WSPP's Hub or
homepage.
B-3.7 Start-up costs and no-load costs if included by the Seller
shall be stated separately in the price.
B-3.8 Energy schedules for the Purchaser's share of a unit may be
modified by the Purchaser with not less than a thirty (30)
minute notice before the hour in which the change is to take
place, unless otherwise mutually agreed or unforeseen system
operating conditions occur.
B-3.9 Unit Commitment Service is intended to have assured
availability; however, scheduled energy deliveries may be
interrupted or curtailed as follows:
(a) By the Seller by giving proper recall notice to the
Purchaser if the Seller and the Purchaser have
mutually agreed to recall provisions,
(b) By the Seller when all or a portion of the output
of the unit is unavailable, by an amount in
proportion to the amount of the reduction in the
output of the

Western Systems Power Pool Original Sheet No. 85
Rate Schedule FERC No. 6

unit, unless otherwise agreed by the schedulers,

(c) By the Seller to prevent system separation during
an emergency, provided the Seller has exercised
all prudent operating alternatives prior to
the interruption or curtailment,

(d) Where applicable, by the Seller to meet its public
utility or statutory obligations to its customers,
or

(e) By either the Seller or the Purchaser due to
the unavailability of transmission capacity
necessary for the delivery of scheduled energy.

B-3.10 Each Party that is a FERC regulated public utility as defined
above in B-3.5 shall file the Confirmation Agreement with FERC
for each transaction under this Service Schedule with a term
in excess of one year no later than 30 days after service
begins if that Party would have been required to file such
Confirmation Agreements or similar agreements with FERC under
an applicable FERC accepted market based rate schedule.

B-4 BILLING AND PAYMENT PROVISIONS:

B-4.1 Except as provided in Sections B-4.2 and B-5, billing for Unit
Commitment Service shall be computed based upon the agreed
upon prices.

B-4.2 In the event the Seller requests recall of Unit Commitment
Service in a shorter time frame than was mutually agreed
pursuant to Section B-3.9(a) and the

Western Systems Power Pool Original Sheet No. 86
Rate Schedule FERC No. 6

Purchaser agrees to allow such recall, the Purchaser shall be
relieved of any obligation to pay start-up costs.

B-5 TERMINATION PROVISION:
In the event Unit Commitment Service is curtailed or interrupted except
as provided in Section B-3.9(a), the Purchaser shall have the option to
cancel the Unit Commitment Service at any time by paying the Seller for
(i) all energy deliveries scheduled up to the notice of termination and
(ii) all separately stated start-up and no-load costs.

procedures, terms, and conditions for requesting and providing Firm
Capacity/Energy Sale or Exchange Service.

C-3 TERMS:

C-3.1 A Party may schedule Firm Capacity/Energy Sale or Exchange
Service from another Party by mutual agreement; provided,
however, that each Party shall be the sole judge as to the
extent to and the conditions under which it is willing to
provide or receive such service hereunder consistent with
statutory requirements and contractual commitments including
the Agreement and any applicable Confirmation Agreement. Once
an agreement is reached, then the obligation for Firm
Capacity/Energy Sale or Exchange Service becomes a firm
commitment, for both Parties, for the agreed service and
terms.

C-3.2 Unless otherwise agreed between the Purchaser and the Seller,
all transactions shall be prescheduled, subject to any
conditions agreed to by schedulers.

C-3.3 Firm capacity transactions shall include buying, selling, or

Western Systems Power Pool First Revised Sheet No. 88
Rate Schedule FERC No. 6 Superseding Original Sheet No. 88

capacity reserves.
C-3.4 Firm energy transactions shall include buying, selling, or
exchanging firm energy between Parties. Subject to mutual

C-3.5 Purchaser shall arrange purchases directly with Sellers.
C-3.6 The price for Firm Capacity/Energy Sale or Exchange Service
shall be mutually agreed to in advance between Seller and
Purchaser and shall not be subject to the rate caps specified
in Section C-3.7 in either of the following two circumstances:
(1) where the Seller is a FERC regulated public utility
and that Seller has been authorized to sell power
like that provided for under this Service Schedule at
market-based rates; or
(2) where the Seller is not a FERC regulated public
utility.
A Party is a FERC regulated public utility if it is a "public
utility" as defined in Section 201(e) of the Federal Power
Act, 16 U.S.C. [sect]. 824(e).
C-3.7 Except as provided for in Section C-3.6, the price shall not

▇▇▇▇▇/kWh; or 21.11 ▇▇▇▇▇/kWh for service of sixteen (16)
hours or less per day. The hourly rate is capped at the
Seller's forecasted Incremental Cost plus 33.78[cent]/kW/day.

period shall not exceed the product of the weekly rate and the

Western Systems Power Pool First Revised Sheet No. 89
Rate Schedule FERC No. 6 Superseding Original Sheet No. 89

highest demand experienced on any day in the seven-day period.
Exchange ratios among such Parties shall be as mutually agreed
between the Purchaser and the Seller, but shall not exceed the
ratio of 1.5 to 1.0. The Seller's forecasted Incremental Cost
discussed above also may include any transmission and/or
ancillary service costs associated with the sale, including
the cost of any transmission and/or ancillary services that
the Seller must take on its own system. Any such transmission
and/or ancillary service charges shall be separately
identified by the Seller to the Purchaser for transactions
under this Schedule including exchanges. The transmission and
ancillary service rate ceiling shall be available through the
WSPP's Hub or homepage. Any such transmission service (and

any applicable transmission tariff or agreement, and the rates
therefore shall be consistent with such tariff or agreement.

C-3.8 Firm Capacity/Energy Sale or Exchange Service shall be
interruptible only if the interruption is: (a) within the
recall time or allowed by other applicable provisions
governing interruptions of service under this Service
Schedule mutually agreed to by the Seller and the Purchaser,
