effective on the Completion Date for the transmission lines being constructed
pursuant to the Funding and Construction Agreement, as the term Completion Date
is defined in Article I thereof, and shall remain in effect until April 15,
2015. It is understood that if such Completion Date does not occur, this
Agreement shall be of no force or effect.

         5.2 The Transmission Service Entitlement to be provided by IID for each
Plant shall be contingent on a Plant Connection Agreement being in effect.
Transmission service for each Plant shall contingent on the Date of initial
Service of such Plant. Producer's Authorized


Representative shall give IID's Authorized Representative written notice of the
Date of Initial Service at least thirty (30) days before the Date of Initial
Service.

6. TRANSMISSION SERVICE:

         6.1 Subject to the terms of this Agreement, IID shall provide to
Producer and Producer shall purchase from IID transmission service over IID's
transmission system for each Plant. IID shall make arrangements with Edison to
provide, at Producer's or Edison's expense, for the transfer of the electrical
power to be delivered to Edison hereunder from IID's transmission system to
Edison's transmission system at the Point(s) of Delivery.

         6.2 The Transmission Service Entitlement for each Plant shall be the
Maximum Transmission Service Entitlement for such Plant specified in Exhibit(s)
II, Transmission Service, or any subsequent Plant Amendments, or such lesser
amount as may be established as follows. Beginning on the Date of Initial
Service for each Plant, Producer shall be entitled to specify a Transmission
Service Entitlement by advance written notice given to IID's Authorized
Representative at least thirty (30) days prior to the Date of Initial Service.
The Transmission Service Entitlement to be provided by IID subsequent to the
Date of Initial Service may be adjusted at six (6) month intervals thereafter
until two (2) years after the Date of Initial Service for such Plant (the "Trial
Period"). Such adjustments shall be made by having Producer's Authorized
Representative give IID's Authorized Representative a ninety (90) day advance
written notice as to the adjustment required. Beginning two (2) years after the
Date of Initial Service for such Plant, Producer shall be entitled to specify a
Transmission Service Entitlement for each successive two-year period during the
remaining term of this Agreement by written notice from Producer's Authorized
Representative to IID's Authorized Representative given at least ninety (90)
days prior to the beginning of each two-year period.


         6.3 The Transmission Service Entitlement selected by Producer for each
Plant in accordance with Section 6.2 may be any amount which is less than or
equal to the Maximum Transmission Service Entitlement for such Plant specified
in Exhibit[s] II, Transmission Service and in any subsequent Plant Amendments,
provided, however, that the following shall apply to each Plant after the Trial
Period for such Plant has elapsed.

         6.3.1 If (i) the sum of the Transmission Service Entitlements for all
Plants which are no longer in their Trial Periods is less than the sum of the
Maximum Transmission Service Entitlements for such Plants, as shown in
Exhibit(s) II, Transmission Service and in any subsequent Plant Amendments, (the
"Aggregate Maximum Transmission Service Entitlement") and (ii) provided that IID
requires additional capacity for transmitting electric power to Edison's
transmission system for another person (or, following the Credit Installment
Period as defined in the Funding and Construction Agreement, for itself) and
(iii) IID's use of such required capacity would be in conflict with Producer's
right as provided herein to increase the sum of the Transmission Service
Entitlements for such Plants to the Aggregate Maximum Transmission Service
Entitlement, then IID shall so notify Producer in writing, specifying in such
notice the portion, expressed in megawatts (MW), of the excess of the Maximum
Transmission Service Entitlement over the Transmission Service Entitlement for
each such Plant which it desires to use as stated above. Producer shall have
ninety (90) days after receipt of IID's notice to notify IID in writing that it
desires to increase the Transmission Service Entitlements of such Plants. To the
extent that Producer does not elect to increase the Transmission Service
Entitlement of each such Plant up to the Maximum Transmission Service
Entitlement for such Plant, IID shall be entitled to use such unclaimed capacity
to satisfy the transmission requirements specified in its notice to Producer,
and to the extent that IID does so, Producer shall thereafter be foreclosed from


increasing the Transmission Service Entitlement for such Plant in a manner which
would conflict with such usage by IID.

         6.3.2 IID shall treat Producer and each other person who has entered
into a transmission service agreement similar in substance to this Agreement in
a fair and nondiscriminatory manner in requesting additional transmission
capacity as provided in this Section 6.3. Without limiting the generality of the
foregoing, IID shall request additional transmission capacity from Producer and
such other persons on a pro rata basis, in proportion to the Aggregate Maximum
Transmission Service Entitlement for each person less the sum of the
Transmission Service Entitlements for each of such persons' generating plants
which is no longer in a Trial Period.

         6.4 In the event that the Original Capacity Nomination designated by
Producer (or the Participant associated with Producer) is adjusted pursuant to
Section 3.07 of the Funding and Construction Agreement, the Parties agree to
amend this Agreement in such a way that the sum of the Maximum Transmission
Service Entitlements for all Plants hereunder is equal to such Original Capacity
Nomination as so adjusted. As used in this Section 6.4, the terms Original
Capacity Nomination and Participant shall have the meanings assigned to them in
Article I of the Funding and Construction Agreement.

         6.5 IID reserves the right to interrupt or curtail the transmission
service provided hereunder as follows:

         6.5.1 If the Operating Transmission Capability is reduced to less than
Normal Transmission Capacity from a Point of Receipt to a Point of Delivery, and
when continuity of service within IID's service area is not being jeopardized,
IID may curtail the transmission service currently being provided from such
Point of Receipt to such Point of Delivery, to an


amount "A" determined by the following formula:

A = Operating Transmission Capability     x     Transmission Service Entitlement
    ---------------------------------
  Normal Transmission Capacity

         The transmission service for each Plant affected shall be curtailed by
multiplying the Transmission Service Entitlement in accordance with Exhibit[s]
II, Transmission Service and in any subsequent Plant Amendments by the same
percentage (expressed as a decimal) as used in the determination of "A."
However, any such curtailment shall occur only after IID has made all reasonable
efforts to eliminate the cause of the reduction in Operating Transmission
Capability, and IID shall then employ reasonable efforts to eliminate
expeditiously the cause of said reduction.

         6.5.2 If continuity of service within IID's control area is being
jeopardized, as determined by IID in its sole judgment, IID may interrupt or
curtail the transmission service provided hereunder to the extent necessary to
avoid or eliminate such jeopardy; provided that (i) such interruptions or
curtailments may be made so that IID may fully utilize all generating resources
owned by it or available to it under contract in order to avoid damage to IID's
electrical system caused by overloading, (ii) such interruption or curtailment
shall occur only after IID has made all reasonable efforts to avoid or eliminate
such jeopardy and (iii) to the extent feasible any curtailment of transmission
service provided hereunder from a Point of Receipt to a Point of Delivery shall
be made in accordance with the formula set forth in Section 6.5.1.

         6.6 If IID's efforts do not avoid or eliminate such jeopardy, the
Parties shall endeavor to develop some other arrangement to avoid or eliminate
such jeopardy and minimize the effects of IID's interruption or curtailment on
both parties.


         6.7 In the event of any curtailments or interruptions made pursuant to
Section 6.5.1 or Section 6.5.2, Producer shall, immediately after being orally
notified by IID, reduce the electrical output of the Plants by the amounts
requested by IID.

         6.8 The transmission service to be provided by IID and purchased by
Producer for each Plant shall not exceed the Transmission Service Entitlement
for that Plant.

         6.9 Subject to Section 6.5, IID shall, during the periods that IID has
agreed to provide the transmission service at the specified Transmission Service
Entitlements, accept hourly scheduled energy deliveries at each Point of Receipt
and simultaneously deliver the same amount of energy (less transmission losses
as provided herein) at the Point(s) of Delivery mutually agreed upon by the
Parties' dispatchers and/or schedulers.

         6.10 Hourly scheduled energy deliveries at each Point of Receipt shall
conform with the practices and procedures developed by the Parties' dispatchers
and schedulers and agreed to by the Authorized Representatives.

7. TRANSMISSION LOSSES:

         7.1 IID shall determine, by transmission power flow analysis, the
electrical losses (expressed as a percent amount of hourly scheduled energy
deliveries) associated with the electrical output from each Plant. Such analysis
shall be performed by IID at its sole expense. The initial percent amount, for
each Plant, representing the electrical losses as determined herein shall be as
specified in Exhibit(s) II, Transmission Service and in any subsequent Plant
Amendments.

         7.2 Unless otherwise agreed to by Producer's and IID's schedulers and
dispatchers, IID shall reduce the amount of all hourly scheduled energy
deliveries for Producer or Producer's



account by the percent amount of such hourly deliveries for each Plant in
accordance with Exhibit(s) II, Transmission Service and in any subsequent Plant
Amendments.

         7.3 If either Party believes that there has been a significant change
in IID's electrical system and the electrical losses associated with any Plant
should be redetermined, either Party's Authorized Representative may submit a
written request to the other Party's Authorized Representative that the
electrical losses be redetermined. Following such request, a transmission flow
analysis shall be performed by IID as approved by the Authorized Representatives
and paid for by the requesting Party. Whenever the percent amount for electrical
losses is redetermined, such percent amount shall become effective as of the
first day of the month following the date of such redetermination; provided,
that such a redetermination may be no sooner than twelve (12) months after the
most recent redetermination. Any redetermination of electrical losses made
pursuant to this Section 7 shall be based on conditions in existence at the time
of such redetermination.

         7.4 Along with the monthly billing pursuant to Section 9.1, for the
transmission service for each Plant, IID shall submit a monthly summary of
hourly scheduled energy deliveries and of electrical losses for each Plant.

8. CHARGES:

         8.1 For transmission service provided by IID, Producer shall pay IID at
aExhibit I.A. The initial rate is specified in Exhibit[s] II, Transmission
Service and revisions thereto will be specified in any subsequent Plant
Amendments. Any specific facility charge to Producer for connecting the Plant(s)
to the IID transmission system shall be included only In the Plant Connection
Agreement(s) between IID and Producer.


         8.2 The transmission rate shall be reviewed annually and may be
revised. Any revision of the rates shall be based on the methodologies In
Exhibit I.A and on the conditions in existence at the time of the revision.
Producer shall have the right to review any exhibits or work papers prepared by
IID to revise the rates.

         8.3 An initial monthly scheduling fee, as specified in Exhibit[s] II,
Transmission Service and revisions thereto specified in any subsequent Plant
Amendments, shall be paid by Producer to IID for those months In which there
were scheduled energy deliveries from the Plant(s). The initial scheduling fee
has been determined by IID pursuant to the methodology specified in Exhibit I.B.
The scheduling fee shall be reviewed annually and may be revised. Any revision
of the scheduling fee shall be based on the methodology in Exhibit I.B and on
the conditions in existence at the time of the revision. Producer shall have the
right to review any exhibits or work papers prepared by IID to revise the
scheduling fee.

9. BILLING AND PAYMENT:

         9.1 IID shall render bills to Producer, beginning in the month of the
Date of Initial Service, on or before the fifteenth (15th) day of each month for
the transmission service to be provided during the month. Producer shall pay
such bills within twenty (20) days after receipt thereof.

         All payments by Producer shall be sent to:

                  Imperial Irrigation District
                  c/o Manager, Finance and Accounting
                  P.O. Box 937
                  Imperial, California 92251


         All billings by IID shall be sent to:



                  Geo East Mesa Limited Partnership
                  P.O. Box 748
                  Holtville, CA 92250

         9.2 Either Party's Authorized Representative may at any time, by
advance written notice to the other Party's Authorized Representative, change
the address to which payments or billings shall be sent.

         9.3 Bills which are not paid in full by said due date shall thereafter
bear an additional charge of one and one-half percent (1-1/2%) per month, or the
maximum legal rate of interest, whichever is less, compounded monthly on the
unpaid amount prorated by days from the due date until payment is received by
IID.

         9.4 In the event any portion of any bill is disputed, the disputed
amount shall be paid when due under protest. If the protested portion of the
payment is found to be incorrect by the Authorized Representatives, the disputed
amount shall be paid by IID to Producer, including interest at the rate of
1-1/2% per month, or the maximum legal rate, whichever is less, compounded
monthly from the date of payment by Producer to the date the refund check or
adjusted bill is received by Producer.

         9.5 For a fractional part of a calendar month at the beginning or end
of the period for which the transmission service is provided hereunder, the
charge pursuant to Section 8.1 shall be proportionately adjusted by the ratio of
days that service is furnished by IID to Producer during such month to the total
number of days in such month.

         9.6 The charge for the transmission service pursuant to Section 8.1
shall be proportionately reduced to the extent the duration of the interruptions
or curtailments of the


transmission service which may occur pursuant to Section 6.5.1 or Section 6.5.2
exceed a cumulative total of twenty-four (24) hours during any calendar month
based on 730 hours per month representing the full transmission service charge.
The amount of such prorata reduction in any month shall reflect the duration and
amount of such interruptions or curtailments which exceed said cumulative 24
hours. Such prorata reduction shall be reflected as a credit to Producer as soon
as possible in a subsequent monthly bill.

         9.7 The charge for the transmission service shall not be reduced if IID
can deliver, but Edison's transmission system cannot receive, the hourly
scheduled energy deliveries independent of the duration of time this condition
exists.

10. LIABILITY:

         10.1 Except for any loss, damage, claim, costs, charge or expense
resulting from Willful Action, neither Party (the "released Party"), its
directors or other governing body, officers or employees shall be liable to the
other Party for any loss, damage, claim, cost, charge, or expense of any kind or
nature incurred by the other Party (including direct, indirect or consequential
loss, damage, claim, cost, charge or expense; and whether or not resulting from
the negligence of a Party, its directors or other governing body, officers,
employees or any person or entity whose negligence would be imputed to a Party)
from engineering, repair, supervision, inspection, testing, protection,
operation, maintenance, replacement, reconstruction, use or ownership of the
released Party's electrical system, Plant(s) or associated facilities in
connection with the implementation of this Agreement. Except for any loss,
damage, claim, cost, charge or expense resulting from Willful Action, each Party
releases the other Party, its directors or other governing body, officers and
employees from any such liability.


         10.2 For the purpose of this Section 10, Willful Action shall be
defined as action taken or not taken by a Party at the direction of its
directors or other governing body, officers or employees having management or
administrative responsibility affecting its performance under this Agreement, as
follows:

         10.2.1 Action which is knowingly or intentionally taken or not taken
with conscious indifference to the consequences thereof or with intent that
injury or damage would result or would probably result therefrom.

         10.2.2 Action which has been determined by final arbitration award or
final judgment or judicial decree to be a material default under this Agreement
and which occurs or continues beyond the time specified in such arbitration
award or judgment or judicial decree for curing such default or, if no time to
cure is specified therein, occurs or continues thereafter beyond a reasonable
time to cure such default.

         10.2.3 Action which is knowingly or intentionally taken or not taken
with the knowledge that such action taken or not taken is a material default
under this Agreement.

         10.3 Willful Action does not include any act or failure to act which is
merely involuntary, accidental or negligent.

         10.4 The phrase "employees having management or administrative
responsibility," as used in Section 10.2, means the employees of a Party who are
responsible for one or more of the executive functions of planning, organizing,
coordinating, directing controlling and supervising such Party's performance
under this Agreement with responsibility for results.

         10.5 Subject to the foregoing provisions of this Section 10, each Party
agrees to defend, indemnify and save harmless the other Party, its officers,
agents, or employees against all losses, claims, demands, costs or expenses for
loss of or damage to property, or injury or death of


persons, which directly or indirectly arise out of the Indemnifying Party's
performance pursuant to this Agreement; provided, however, that a Party shall be
solely responsible for any such losses, claims, demands, costs or expenses which
result from its sole negligence or Willful Action.

11. AUDITING

         11.1 IID shall make its books, records, and other supporting
information, as requested, available to Producer or to Producer's designated
contracted representative(s) with a CPA firm, for the purpose of auditing any
charges or accounts to be kept by IID hereunder. All such audits shall be
undertaken at reasonable times and in conformance with generally-accepted
auditing standards.

         11.2 If as a result of such audits Producer believes its charges or
accounts should be adjusted, the findings shall be presented to the Authorized
Representatives. If the Authorized Representatives agree that any audit finding
should result in a revision of charges or accounts, such revisions shall be
retroactive to the first billing for such charges and accounts and shall be made
as soon as practical after determination.

         11.3 The amount of any unresolved dispute shall accrue interest at the
rate of one and one-half percent (1-1/2%) per month, or the maximum legal rate,
whichever is less, compounded monthly for any amount of money ultimately
refunded to Producer.

12. AUTHORIZED REPRESENTATIVES: Within thirty (30) calendar days after the
Completion Date, as defined in Article I of the Funding and Construction
Agreement, each Party shall designate by written notice to the other Party a
representative who is authorized to act on its behalf in the implementation of
this Agreement. Either Party may at any time change the designation of its
Authorized Representative by written notice to the other Party.


13. NO DEDICATION OF FACILITIES: Any undertaking by one Party to the other Party
under any provision of this Agreement shall not constitute the dedication of the
system or any portion thereof of the 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 its obligations
hereunder. 14. NON-WAIVER: None of the provisions of this Agreement shall be
considered waived by either Party except when such waiver is given in writing.
The failure of either Party to insist in any one or more instances upon strict
performance of any of the provisions of this Agreement or to take advantage of
any of its rights hereunder shall not be construed as a waiver of any such
provisions or the relinquishment of any such rights for the future, but the same
shall continue and remain in full force and effect.

15. NO THIRD PARTY RIGHTS: The Parties do not intend to create rights in or to
grant remedies to any Third Party or others as a beneficiary of this Agreement
or of any duty, covenant, obligation or undertaking established hereunder.

16. UNCONTROLLABLE FORCES: Neither Party shall be considered to be in default in
the performance of any of its obligations under this Agreement when a failure of
performance shall be due to an uncontrollable force. The term "uncontrollable
force" shall mean any cause beyond the control of the Party affected including,
but not restricted to, failure of or threat of failure of facilities which have
been maintained in accordance with generally-accepted engineering and operating
practices in the electrical utility industry, flood, drought, earthquake,
tornado, storm, fire, pestilence, lightning and other natural catastrophes,
epidemic, war, riot, civil disturbance or disobedience, strike, labor dispute,
labor or material shortage, sabotage, government priorities and restraint by
court order or public authority (whether valid or invalid) and actions or


nonaction by or inability to obtain or keep the necessary authorizations or
approvals from any governmental agency or authority, the failure or inability of
Edison to receive the electric power to be transmitted hereunder at the Point(s)
of Delivery, which by exercise of due diligence such Party, could not reasonably
have been expected to avoid and which by exercise of due diligence it has been
unable to overcome. Nothing contained herein shall be construed as to require a
Party to settle any strike or labor dispute in which it may be involved. Either
Party rendered unable to fulfill any of its obligations under this Agreement by
reason of an uncontrollable force shall give prompt written notice of such fact
to the other Party and shall exercise due diligence to remove such inability
with all reasonable dispatch.

17. ASSIGNMENTS:

         17.1 Any assignment by Producer of its interest in this Agreement which
is made without the written consent of IID (which shall not be unreasonably
withheld) shall not relieve Producer from its primary liability for any of its
duties and obligations hereunder, and in the event of any such assignment
Producer shall continue to remain primarily liable for payment of any and all
money due IID hereunder and for the performance and observance of all other
covenants, duties and obligations to be performed and observed hereunder by it
to the same extent as though no assignment has been made.

         17.2 Notwithstanding any provision of Section 17.1 to the contrary,
prior to the end of the Credit Installment Period, as defined in Article I of
the Funding and Construction Agreement, Producer's right to transmission service
under this Agreement with respect to one or more of the Plants may be assigned
only (i) to a purchaser or co-owner of such Plants or to a person who will
operate such Plants pursuant to a contract or other arrangement with such

                       DEVELOPMENT AND METHODOLOGY FOR THE
                           TRANSMISSION SERVICE CHARGE

IID's transmission service charge shall be recalculated during the month of
April of each year, using the methodology summarized in this Exhibit. The
recalculated transmission service charge shall be effective on June 1 of the
year of recalculation.

EI.A-1 Plant Investment

     TAI= WP + PA - TR + GP + M&S

where

     TAI= Total adjusted investment at the time of calculation.

     WP = Estimate of weighted Transmission Plant Cost ($40,980,291) as
          December 31, 1983 calculated using the following formula:

          WP=  (0.7 x OC) + (0.3 x RCN); where

          0C=  Cumulative original cost of Transmission Plant as shown in IID's
               accounting records, obtained by summing the actual cost of all
               yearly additions to Transmission Plant from 1938 to the end of
               1983, (i.e., $20,700,415).

          RCN= Estimate of the cumulative reproduction cost to build the
               Transmission Plant items identified in OC in 1983 dollars.
               Calculated by summing the escalated cost of each yearly addition
               to Transmission Plant starting in 1938 up to the end of calendar
               year 1983 using the Handy-Whitman Index for Total Transmission
               Plant for the Pacific Region, (i.e., $88,300,000).

     PA = Cumulative sum of additions to Transmission Plant from January 1,
          1984 to the end of the year preceding the year of calculation. Thus,
          if the calculation takes place in 1996, PA is sum of Transmission
          Plant additions at actual cost from January 1, 1984 to December 31,
          1995.

          PA = Sum of [TPA(i) + OA(i)]

          where TPA(i)=  Annual additions to Transmission Plant for each year
                         associated with the Transmission Project, as defined in
                         Section 7.05 of the Funding and Construction Agreement.
                         TPA(i) is calculated for each year from Completion Date
                         of Transmission Project to end of year preceding year
                         of calculation.

               OA(i)  =  Other annual additions to Transmission Plant by IID
                         each year. OA(i) is calculated for each year from
                         January 1, 1984 to end of year preceding year of
                         calculation.



     TR = Sum of (i) and (ii) where:

     (i)= For facilities placed in service prior to 1984, the cumulative sum of
          the annual Weighted Retirement Costs (WRC) for retirements from
          Transmission Plant from January 1, 1984 to the end of the year
          preceding the year of calculation. Thus, if the calculation takes
          place in 1996, TR is comprised of the sum of annual Transmission Plant
          retirements from January 1, 1984 to December 31, 1995 with each
          year's original cost adjusted to account for the weighted cost of
          retirement.

          where WRC = Weighted Retirement Cost for transmission retired in
                      a given year.

                OCI = Original cost of transmission facilities retired in a
                      given year.

          WRC = 70%*OCI + 30%*OCI*RCN/OC

     (ii) = Cumulative sum of original cost of annual transmission retirements
            for facilities placed in service after January 1, 1984.

     GP = General plant investment as shown in IID's accounting records, as of
          the year preceding the year of calculation, allocated to transmission
          use by the ratio of total allocated transmission O&M cost to the sum
          of production O&M cost excluding fuel, distribution O&M cost,
          transmission O&M cost, dispatching cost, and customer accounting and
          services costs.

    M&S = Materials and supplies inventory held by IID as of the year preceding
          the year of calculation, allocated to transmission use by the ratio of
          Transmission Plant Original Cost to Total Electric Plant original cost
          as reflected in IID's accounting records for the year preceeding the
          year of calculation.

EI.A-2 Annual Cost

     TAC= (1.25 x CRF x TAI) + OM + A&G

     Where

     TAC= Total Annual Cost.

     CRF= Annual capital recovery factor calculated for a 33-year amortization
          using the average interest rate for the year preceding the year of
          calculation from the "Merrill Lynch 500 Municipal Bond Index
          Electric-Retail."

     OM = Total allocated transmission O&M cost during the year preceding the
          year of calculation, equal to the sum of (i) dispatching costs and
          (ii) transmission O&M cost allocated to transmission use by the ratio
          of Transmission Plant original cost (OC) to Total Transmission Plant
          original cost (including the cost of subtransmission plant) as shown
          in IID's accounting records.

     A&G= Administrative and general cost during the year preceding the year of
          calculation, allocated to transmission use by the ratio of total
          allocated transmission cost (OM) to the sum of production O&M cost
          excluding fuel, distribution O&M cost, transmission O&M cost,
          dispatching cost, and customer accounting and services cost.



          Administrative and general cost is comprised of Power Department plus
          Joint Department A&G less Customer Account Expense.

EI.A-3 Monthly Transmission Service Charge

     TSC =    TAC
            --------
            12 x APL

     where

     TSC = Monthly transmission service charge, in $/kW.

     APL = Annual peak load during the year preceding the year of calculation,
          expressed in kW, which is equal to the sum of IID's service peak load
          plus all transmission wheeling commitments (including all Transmission
          Service Entitlements).

                 METHODOLOGY AND CALCULATION OF SCHEDULING FEE

                              ANNUAL DETERMINATION
                                       OF
                              IID SCHEDULING FEES

     IID, in April each year, will calculate monthly fees for scheduling
services related to Alternative Energy Resources and transactions with other
utilities as follows:

     A.   An appropriate number of scheduling units will be assigned to every
          IID resource, Alternative Energy Resource, and transaction with other
          utilities in operation during the preceeding year. The number of
          scheduling units assigned to each resource and/or transaction will
          depend upon the total daily number of functions and therefore,
          estimated time required to schedule the resource and/or transaction.
          This estimate will be directly related to the complexity of the
          scheduling service being provided. Table 1 shows how the total
          scheduling units were determined for the IID system.

     B.   The expenses related to dispatching and scheduling services will be
          equal to the sum of the following:

          1.   IID FPC Account 556 for the year preceeding the year of
               calculation

          2.   A portion of the annual expenses related to the SCADA and AGC
               systems for the year preceeding the year of calculation,
               determined by multiplying one half of the levelized debt service
               payments for the systems by the percentage that FPC Account 556
               is of the total of FPC Accounts 556, 561 and 581. Table 2 shows
               calculations involved with this step.

     C.   The annual scheduling fee per scheduling unit will be determined by
          dividing the expenses related to scheduling found in Step B by the
          total scheduling units from Step A. The per unit fee will then be
          multiplied by the number of scheduling units assigned to each resource
          and/or transaction to develop an appropriate annual scheduling fee for
          that resource and/or transaction. The monthly scheduling fee will then
          be calculated by dividing the annual fee by 12. Table 3 shows the
          calculation.

The revised scheduling fee will be effective on June 1 of the year in which they
are calculated.
