I. Firm Transmission Service

A) Long Term Firm Transmission

Long Term Firm Transmission Service (for periods of one year or longer) is available on a first-come, first serve basis.  Entergy offers a Sliding Yearly service, which may start at 00:00 on the first date of any calendar month and end at 00:00 on the first date of the same month during the next year, or any year thereafter. Customers can schedule for less than one year; provided however, such customers will be required to pay for the entire reservation. Customers must submit their request in writing and via the Entergy OASIS at least 60 days in advance of the calendar month in which the service is to commence. Customers who desire a system impact study should submit their requests at least 90 days prior to the start of service.  However, Entergy will use due diligence in completing the system impact study  for requests submitted less than 90 days prior to the start of service.  Irrespective of a request’s submission date, service will not commence until the study is complete.  Entergy will respond within 30 days of its receipt of the completed application with: (i) an acceptance; (ii) an offer to perform a System Impact Study; or (iii) an offer for partial service. Customers must then confirm, withdraw or submit an executed study agreement within 15 days after receiving Entergy's response. If customers fail to take one of these actions, then their requests will be deemed withdrawn and the status on the Entergy OASIS will be changed to “RETRACTED.”

B) Short Term Firm Transmission

Short Term Firm Transmission Service is available in monthly, weekly, and daily increments.  Customers who desire a system impact study should attempt to submit their requests at least 90 days prior to the start of service.  Entergy will use due diligence in completing the system impact study for requests submitted less than 90 days prior to the start of service.  However, as with requests for long-term firm service, irrespective of a request’s submission date, service will not commence until the study is complete.  

Entergy offers a Fixed Monthly Firm Transmission Service. This service starts at 00:00 on the first date of a calendar month and stops at 24:00 on the last date of the same calendar month (same as 00:00 of the first date of the next consecutive month). When requesting this service, the “service duration” may be in monthly increments, but the total reservation service duration must be 11 months, or less.  For Fixed Monthly Firm Transmission Service (as well as all other transmission services offered by Entergy), service duration is the time between the begin date and time of the reservation and the end date and time of the reservation.  The MW profile is not used to determine the service duration. Monthly service is for 24 hours per day for the entire calendar month. Customers may schedule for less than one month, but they will be required to pay for the entire reservation. Customers must submit their request via the Entergy OASIS earlier than 12:00 noon the day before the service is to begin. Entergy normally will respond within 30 days of its receipt of the completed application with: (i) an acceptance; (ii) an offer to perform a System Impact Study; or (iii) an offer for partial service.  For accepted or counter offered requests, customers must confirm or withdraw their request within 96 hours after receiving Entergy response; otherwise, the request will be deemed withdrawn and the status will be changed to RETRACTED.  If a system impact study is required, then the study agreement must be executed and returned to Entergy within 15 days.

Entergy offers a Fixed/Sliding Weekly Firm Transmission Service. This service starts at 00:00 of any date and stops exactly 168 hours later at 00:00 on the same day of the next week. When requesting this service, the service duration can be in weekly increments, but the total reservation service duration must be 3 weeks, or less. Weekly service is for 24 hours per day for the entire week of service. Customers may schedule for less than one week, but they will be required to pay for the entire reservation. Customers must submit their request via the Entergy OASIS earlier than 12:00 noon the day before the service is to begin. Entergy will respond within 30 days of its receipt of the completed application with: (i) an acceptance; (ii) a refusal; or (iii) an offer to perform a System Impact Study, if the customer indicates interest in a study at the time of the request. Customers must then confirm or withdraw their request within 48 hours after receiving Entergy’s response; otherwise, the request will be deemed withdrawn and the status will be changed to RETRACTED.

Entergy offers a Fixed Daily Firm Transmission Service.  The service starts at 00:00 and stops at 24:00 of the same calendar date (same as 00:00 of the next consecutive calendar date). The requested service duration can be in daily increments, but the total reservation service duration must be 6 days, or less. Customers can schedule for less than one day, but they will be required to pay for the entire reservation. Customers must submit their request via the Entergy OASIS earlier than 12:00 noon the day before the service is to begin. Entergy will respond within 30 days of receipt of the completed application.

Entergy will make best efforts to respond within 72 hours, or prior to the scheduling deadline, whichever is earlier, to a request for Daily Firm service received during period 2 - 30 days ahead of the service start time. Customers must then confirm or withdraw their request within 24 hours after receiving Entergy’s response; otherwise, the request will be deemed withdrawn and the status will be changed to RETRACTED.

Entergy will make best efforts to respond to a request for Daily Firm service received less than 24 hours ahead of the service start time. Customers must then confirm or withdraw their request within 2 hours after receiving Entergy’s response; otherwise, the request will be deemed withdrawn and the status will be changed to RETRACTED.

D) Compensation - Firm Transmission Products

The Transmission Customer shall compensate Entergy each month for reserved point-to-point capacity  per posted prices. 

The total maximum charge for hourly transmission service will not exceed the rate for daily service using the highest amount of hourly service reserved during any hour of the day. Likewise, the maximum charge for daily will not exceed the rate for weekly service using the highest amount of hourly or daily reserved in any hour during the week. 

These prices do not include the price of ANY ancillary services.  Two ancillary services must be taken from Entergy: Schedule 1 - Scheduling, System Control and Dispatch Service; and Schedule 2 - Reactive Supply and Voltage Control from Generation Sources Services. These prices are also exclusive of applicable charges for losses.

II. Non-Firm Transmission Service

A) General

Entergy sells four different non-firm transmission products for monthly, weekly, daily and hourly increments. The Transmission Customer may reserve a sequential term of service so that the total time period for which the reservation applies is greater than the initial time period. All requests for the non-firm transmission service should be submitted over the Entergy OASIS.  

Entergy offers a Fixed Monthly Non-Firm Transmission Service. This service starts at 00:00 on the first date of a calendar month and stops at 24:00 on the last date of the same calendar month (same as 00:00 of the first date of the next consecutive month). The requested service duration can be in monthly increments, but the total reservation service duration must be 11 months, or less. Monthly service is for 24 hours per day for the entire calendar month. Customers can schedule for less than one month, but they will be required to pay for the entire reservation. Customers must submit their request via the Entergy OASIS no earlier than 60 days before the service is to commence. Entergy will respond within 2 days of receiving the request. Customers must then confirm or withdraw their request within 24 hours of receiving Entergy’s response; otherwise, the request will be deemed withdrawn and the status will be changed to RETRACTED.

Entergy offers a Fixed/Sliding Weekly Non-Firm Transmission Service. The service starts at 00:00 of any date and stops exactly 168 hours later at 00:00 on the same day of the next week. The requested service duration may be in weekly increments, but the total reservation service duration must be 3 weeks, or less. Weekly service is for 24 hours per day for the entire week of service. Customers can schedule for less than one week, but they will be required to pay for the entire reservation. Customers must submit their request via the Entergy OASIS, no earlier than 14 days before the service is to commence. Entergy will respond within 4 hours of receiving the request. Customers must then confirm or withdraw their request within 24 hours of receiving Entergy’s response; otherwise, the request will be deemed withdrawn and the status will be changed to RETRACTED.

Entergy offers a Fixed Daily Non-Firm Transmission Service. The service starts at 00:00 and stops at 24:00 of the same calendar date (same as 00:00 of the next consecutive calendar date). The service duration can be in daily increments, but the total reservation service duration must be 6 days, or less. Customers can schedule for less than one day, but they will be required to pay for the entire reservation. Customers must submit their request via the Entergy OASIS no earlier than 2 days before the service is to commence. Entergy will respond within 30 minutes of receiving the request. Customers must then confirm or withdraw their request within 2 hours of receiving Entergy’s response; otherwise, the request will be deemed withdrawn and the status will be changed to RETRACTED.

Entergy offers a Fixed Hourly Non-Firm Transmission Service. The service starts at the beginning of a clock hour and stops at the end of a clock hour. The service duration can be in hourly increments, but the total reservation service duration must be 23 hours, or less. Customers must submit their request via the Entergy OASIS no earlier than 12:00 noon the day before the service is to commence. Entergy will respond within 30 minutes of receiving the request for the requests received earlier than 1 hour before the service is to commence. Entergy will make best efforts to respond to the requests received later than 1 hour before the service to commence. Customers must then confirm or withdraw their requests within 30 minutes of receiving Entergy’s response for the requests that are received earlier than 1 hour before the start of the service, and within 5 minutes for the requests that are received later than 1 hour before the start of the service; otherwise, the request will be deemed withdrawn and the status will be changed to RETRACTED.

Entergy undertakes no obligation under the tariff to plan its transmission system in order to provide sufficient capacity for Non-Firm Transmission Service. Parties requesting Non-Firm Transmission Service for the transmission of firm power must recognize that such service is subject to availability and to Curtailment or Interruption under the terms of the tariff. Note that Hourly Non-Firm service is only sold as Fixed Point-to-Point Transmission Service.  The point of receipt and the point of delivery are not changeable. 

B) Compensation - Non-Firm Transmission Products

The Transmission Customer shall compensate Entergy each month for reserved point-to-point capacity per posted prices.

The total maximum charge for hourly will not exceed the rate for daily service using the highest amount of hourly service reserved during any hour of the day. Likewise, the maximum charge for daily will not exceed the rate for weekly service using the highest amount of hourly or daily reserved in any hour during the week. 

The prices shown above are the maximum prices as filed with FERC.  Entergy reserves the right to discount these prices and makes them available to all customers on a non-discriminatory basis.  Please see the offerings for the latest discounted prices for Non-Firm Transmission Services.  These prices do not include the price of ANY ancillary services.  Two ancillary services must be taken from Entergy: Schedule 1 - Scheduling, System Control and Dispatch Service; and Schedule 2 - Reactive Supply and Voltage Control from Generation Sources Services. These prices are also exclusive of applicable charges for losses and applicable taxes.

C) Using Emergency Assistance

Entergy requires all customers receiving emergency assistance that uses transmission service on Entergy’s system to submit an OASIS reservation after the fact. It is the responsibility of the sink control area to make sure that the reservation is entered. For sink control areas that are not network customers of Entergy the type "PTP EMERGENCY ASSIST" should be used. For sink control areas that are network customers of Entergy the type "NETWORK EMERGENCY ASSIST" should be used. The reservations covering the emergency assist should be entered as soon as practicable, but within 24 hours of the start of the emergency assist schedule.

III. Redirect of Point to Point Service

Modifications to Transmission Service

Modifications to transmission service pursuant to Entergy's OATT sections 22.1 and 22.2 should be submitted via OASIS using the REDIRECT function as described in the FERC Standards & Communications Protocol.  Entergy's business practices pertaining to service modifications are described below.

1) General

1. Only confirmed firm reservation requests may be REDIRECTED.

2. REDIRECT requests may not extend beyond the start and end times of the original request.

3. The new request must:

1. be assigned either the FIRM or NF HOURLY REDIRECT services,

2. be assigned the REDIRECT request type, and

3. include the ASSIGNMENT_REF of their original reservation.

1. Effective March 12, 2001, Entergy will no longer approve requests for alternate path service which are submitted with REQUEST_TYPE = ORIGINAL.

2. Only ORIGINAL, MATCHING, RENEWAL and firm REDIRECT reservations may be redirected. Requests that have been redirected on a non-firm basis may not be REDIRECTED.

3. This protocol does not support a REDIRECT from multiple reservations. This change will facilitate automation of the request verification process and allow Entergy to further expedite request processing.

2) Procedure for Modification on a Non-Firm Basis Under 22.1 of the Tariff

1. As available, Entergy transmission customers with confirmed firm transmission reservations may take service over secondary receipt and delivery points on a non-firm basis.

2. Requests to take service over secondary POR and/or POD on a non-firm basis should be submitted via OASIS using the REDIRECT function.

3. The sum of all firm schedules and secondary reservations shall not exceed the capacity of the original firm reservation.

4. The customer retains the right to schedule firm PTP service at the POR and/or POD of the original request.

5. The REDIRECT request must include the assignment number of the original request in the related reference field.

6. Secondary REDIRECT requests may be submitted only in the NF HOURLY REDIRECT service.

3) Procedure for Modification on a Firm Basis Under 22.2 of the Tariff

1. As available, Entergy's transmission customers may modify the source/sink or POR/POD of confirmed firm point-to-point service on a firm basis at no additional cost per section 22.2 and Attachment ‘M’ of the OATT.

2. Requests to modify on a firm basis will be treated as a new request for firm service.

3. Requests to modify on a short-term firm basis must be submitted via OASIS using the REDIRECT function no later than 12:00 noon on the day prior to the start of the redirected service. Requests to modify on a long-term firm basis (twelve months or longer) will be processed according to the current business practices for original long-term firm service.

4. The REDIRECT request must include the assignment number of the original request in the related reference field.

5. Requests to modify on a firm basis will be declined if the desired capacity of the original has already been scheduled.

6. Requests to modify on a firm basis may be submitted in daily, weekly, monthly, or yearly service increments.

7. Requests to modify on a firm basis must be within the time interval of original reservation (the REDIRECT cannot start before the original start date or end after the original end date).

8. The customer will lose the rights to the redirected service of the original reservation when the REDIRECT reservation is confirmed by the customer and it passes the conditional reservation deadline under section 13.2 of the OATT.

9. When applicable, rollover rights will be given on the original reservation only.

IV. Resale of Point to Point Service

INTERIM BUSINESS PRACTICE FOR ASSIGNMENT OF POINT-TO-POINT TRANSMISSION SERVICE UNDER SECTION 23 OF ENTERGY OATT 

This Interim Business Practice governs the resale, assignment or transfer of Point-To-Point Transmission Service under Section 23 of Entergy’s Open Access Transmission Tariff (“OATT”) until the necessary OASIS functionality has been approved by the North American Energy Standards Board (“NAESB”) and the Federal Energy Regulatory Commission (“FERC”) and is available. A Transmission Customer (“the Assignor”) may sell, assign, or transfer all or a portion of its Long- and Short-Term Firm or Non-Firm Point-to-Point Transmission Service rights under an existing Transmission Service Agreement (”TSA”) to another Transmission Customer or Eligible Customer (“the Assignee”) as defined in Entergy’s OATT. Any resale, assignment or transfer of Transmission Service must concern the same type, class, and increment of service as the original transmission service reservation (“TSR”) regardless of whether the Assignee is a new or existing or Transmission Customer (i.e., monthly firm Service cannot be resold or assigned in weekly increments of firm Service). The Assignee must execute, or already be a signatory to an existing, Form of Service Agreement for the Resale, Reassignment or Transfer of Point-to-Point Service under the Entergy OATT before assigned, resold, or transferred service commences.  This agreement is Attachment A-1 (“Form A-1”) to the Entergy OATT and is posted on OASIS under the “FAX FORMS” link. Once completed, the Assignee must fax an executed Form A-1 to Entergy Transmission Services at 601- 985-2923. The Assignor must notify the Independent Coordinator of Transmission of the impending transaction by inputting the reassignment in OASIS. All resales, assignments, or transfers of Transmission Service MUST BE POSTED ON OASIS before the resold, assigned or transferred service commences. When reselling, assigning or transferring Transmission Service, the Assignor and the Assignee must allow Entergy sufficient time to evaluate the Assignee’s eligibility to become a Transmission Customer under the Entergy OATT before implementing a resale, assignment or transfer, which evaluation includes ensuring that the Assignee is creditworthy under the Entergy’s OATT. Assignees that are not existing Transmission Customers should utilize the existing procedures under the OATT to become a Transmission Customer and to execute Form A-1 for all resold, assigned or transferred Transmission Service. Assignees that are existing Transmission Customers will be required to execute a discrete Form A-1 for every resale, assignment or transfer of long-term firm Point-to-Point Transmission Service. Form A-1, however, can also be used by existing Transmission Customers as an umbrella Service Agreement for the resale, reassignment, or transfer of Short-Term Firm and Non-Firm Transmission Service.  When transacting under an umbrella Form A-1, transaction specifications (i.e., price, term, Point of Delivery, Point of Receipt) are made part of the TSA and, thus, contractually binding on the parties by inputting them into the reassignment posted on OASIS, as discussed below. Additionally, applicable specifications must be input into the reassignment posted on OASIS as discussed below. Where the Assignor and Assignee agree that the Assignee will replace the Assignor for the entire reassigned capacity and will contractually undertake all of the Assignor’s liabilities associated therewith, a non-conforming TSA may be completed, executed between the Assignee and Entergy, and filed with FERC.  Transmission Customers contemplating the execution of a non-conforming TSA must contact Entergy’s Transmission Services at 504-576- 4458 (Dennis Broussard) or 601-985-2899 (Buzz Howard) to initiate that process. Assignors and Assignees must follow Entergy’s interim OASIS procedures described below, otherwise their resale, assignment or transfer will be deemed invalid by Entergy. Entergy’s interim OASIS procedures are as follows:

1. Assignment of Long-Term and Short-Term Firm and Non-Firm Point-to-Point Transmission Service: Until the necessary NAESB-approved OASIS functionality is in place, all resales, assignments or transfers of Long-Term Firm, Short-Term Firm, and Non-Firm Point-to-Point Transmission Service must be conducted on OASIS to ensure that the proper entity is billed. The following OASIS procedures must be followed and performed prior to commencement of the reassigned, resold, or transferred service in order to ensure that a resale, assignment or transfer is properly implemented:

a. Login to OASIS using the appropriate OASIS certificate.

b. From the Entergy OASIS home page, select the “Post Reassignment” link.

c. On the “Post Reassignment” page, in the block entitled “Customer Information”, select the entity that will be the purchaser of the service being resold, assigned, or transferred.

d. In the “Dates and Times” block, select both start and stop time periods for the service being resold or assigned.

e. In the “Service Information” block, select the transmission product that is being resold or assigned, fill in the “Capacity Granted” field with the MW amount of service being resold or assigned, fill in the “Offer Price” field with the negotiated rate for the resale, assignment or transfer, and select “confirmed” as the “Status” of the resale or assignment.

f. In the “Path and POR/POD Information” block, select the same Path or POR and POD as the original TSR.

g. Seller comments can be added to the transaction utilizing the “Seller Comments” field in the “Seller Information” block.

h. After reviewing your entries and selections for accuracy, select the “ADD REASSIGNMENT” button at the bottom of the page.

i. If a resale or assignment has successfully posted to OASIS, a new OASIS page with a block entitled “Reassignment Information” will load. In the “Reassignment Information” block, enter the original TSR Assignment Reference in the “Reassignment Ref” field and enter the amount of Service (MW) being resold or assigned in the “Reassigned Capacity” field. Verify the accuracy of the Start & Stop Dates and Times for correctness. After all information is verified for correctness, select the “Submit” button. The “Post Reassignment” page will then re-load.

j. Below the “Add Reassignment” button, the correct Reference, Capacity Reassigned, Offer Price, Start Time Reassigned, and Stop Time Reassigned will appear. If this information is correct, select the “Submit” button.

k. A new OASIS page will load with a new OASIS Assignment Reference for the amount of Service being resold, assigned or transferred.

2. Invoicing of Resold or Assigned Transmission Service: If the procedures outlined above are followed (including the execution of Form A-1), Entergy will invoice the Assignee for the resold, assigned, or transferred Transmission Service and credit or debit the Assignor any amounts due based on the difference between the rate negotiated with the Assignee and the Assignor (the “offer price” field) and the tariff rate after payment has been received from the Assignor. Note, however,

l. If the negotiated rate is less than the original rate specified in the Assignor’s Service Agreement, the Assignor remains liable for the difference between the negotiated rate and the original rate; and

m. If the negotiated rate is more than the original rate specified in the Assignor’s Service Agreement, Entergy will credit the Assignor the difference between the negotiated rate and the original rate only after payment has been received from the Assignee.

If the resale, assignment or transfer of Transmission Service is made to an Assignee contrary to the procedures set forth above, Entergy will invoice the Assignor for the resold, assigned, or transferred Transmission Service at the applicable OATT rate. If a non-conforming TSA is completed, executed, filed, and accepted by FERC, Entergy will invoice the Assignee directly for all costs associated with the reassigned, resold, or transferred service and will not be responsible for any credits, debits, or other costs or expenses other than as agreed by all parties in the non-conforming TSA.

V. Loss Compensation Service

Capacity and energy losses occur when Entergy delivers electricity across its transmission facilities for a Transmission Customer.  Transmission Customers are required to make their own arrangements for providing losses.  All NERC tags utilizing Entergy's Point-to-Point Transmission Service must indicate how the transmission losses will be supplied in the loss accounting section of the tag.  For each Point-to-Point transaction, the losses for that transaction must be supplied at the point of receipt (POR) for that transaction.  This applies to all transactions using point-to-point transmission service, including wheels, imports, exports, and transactions that are internal to the Entergy Balancing Authority.  The loss factor on the Entergy System is 1.03.  The energy received at Entergy’s POR must be equal to the energy scheduled to the point of delivery (POD) multiplied by the loss factor (1.03) and rounded up to the next whole MW.  In order for the tag to be implemented, the loss accounting must be distributed evenly throughout the duration of the transaction.   Several examples are provided below.  Questions about Entergy’s loss provision business practice should be directed to Melinda Montgomery by email at mmontg3@entergy.com or by telephone, 870-541-4578.

2	40	38	76	78.28	2	3
3	39	38	114	117.42	1	4

A valid tag must meet the following validations:

· Loss type is in-kind (InK)

· Losses provided on the entire tag must be 1.03 x POD rounded to the next whole MW.

· Losses provided for the first segment of the energy profile must be at least

1.03 x POD rounded to the next whole MW.

· Total losses provided after each subsequent segment must also equal at least

1.03 x POD rounded to the next whole MW.

VI. Discounts

There are an infinite number of possible discounts that could be offered depending on the season, time of day, and duration for which the transmission products are required. If Entergy offers a rate discount to any customer, or attributes a discounted transmission rate to its own transactions, Entergy must simultaneously offer the same discounted rate for the same period of time to all eligible customers on the same path and all other unconstrained paths serving the same point of delivery as the originally discounted service.

Currently, Entergy does not offer discounts on Non-Firm Transmission Services. The prices are posted under offerings on OASIS. These prices do not include ANY ancillary services, losses or applicable taxes.

VII. Release of Non-Firm ATC held under Firm Reservations

On July 25, 2000, Entergy Transmission implemented a program that updates the posted numbers for non-firm ATC based on actual schedules received on firm reservations during the Operating Horizon. The Operating Horizon currently begins at 4:00 P.M. each day for the upcoming day. The program ingests NERC E-tags as they are implemented and updates the non-firm ATC figures accordingly. These updates usually occur within five minutes from when the E-tag is implemented. Effective August 21, 2000, Entergy will modify its business practices for the release of unscheduled ATC held under firm reservations to the non-firm market as follows:

· The Planning Horizon for a given day is defined as anytime before Noon on the prior day. The Operating Horizon for a given day will begin at Noon on the prior day.

· In the Planning Horizon, non-firm ATC will be equal to the TTC less all OASIS reservations.

· In the Operating Horizon, posted non-firm ATC numbers will be equal to the TTC less schedules under firm reservations and less non-firm reservations.

· Entergy will not release any non-firm capacity held under firm reservations until the Operating Horizon.

Entergy has chosen Noon prior day as the beginning of the Operating Horizon in order to make additional non-firm ATC available to the market when Daily Non-Firm as well as Hourly Non-Firm capacity can be purchased. Entergy will continue the practice of accepting schedules under firm reservations up to twenty minutes prior to the start of the schedules. However, please be aware that this increases the chance that non-firm schedules may be curtailed as firm schedules are submitted. Curtailments of non-firm transmission service will be based on NERC curtailment priorities.

VIII. Reservation/Scheduling Requirements

A) General

The implementation of order 638 requires that Entergy stop accepting OASIS reservations for a constrained interface when the sum total of the accepted and confirmed requests exceed the posted ATC. The result is that if a transmission customer submits multiple unconfirmed OASIS requests in excess of the posted ATC for a single constrained interface, Entergy cannot accept subsequent requests unless the original requests are withdrawn or the confirmation time limit expires. In an attempt to address this situation, Entergy has implemented a business practice by which it will reject additional OASIS requests if ATC is unavailable due to pending accepted requests. Entergy will not hold these requests in the queue. This practice will prevent a customer from blocking the queue for an extended period by submitting multiple unconfirmed requests above the posted ATC before confirming or withdrawing their initial requests. Customers can check the posted ATC and review the queue for "accepted" requests to determine when ATC will become available if accepted requests are not confirmed.

Firm requests for next day business must be queued into the Entergy Oasis by 12:00 PM CPT and Daily Non-Firm requests must be queued in by 2:00 PM

This product requires that the buyer specify the point of delivery into the Entergy Transmission System and the point of exit from the Entergy Transmission System.

Source and Sink information must be provided in accordance with the requirements of Attachment M of the Entergy tariff.

The transmission reservation amount is specified at the point of receipt and applies for the entire time period reserved. The amount of transmission actually scheduled does not have to equal the amount reserved but the actual amount scheduled cannot exceed the reservation and the bill is based on the reservation at the point-of-receipt.  

There is no forgiveness of transmission service charges when transmission restrictions occur for reliability reasons on the interconnected transmission system (external to Entergy) and as a result the energy flowing over Entergy's transmission service must be curtailed.

C) Rules for changes in sources and sinks 

A first-tier control area is defined as any control area outside the Entergy Transmission System with direct ties to the Entergy control area. A second-tier control area is defined as a control area that does not have direct ties to the Entergy control area. For transmission reservation requests that originate or sink in a first-tier control area, Entergy will evaluate the requests based on the available transfer capability between Entergy and the source/sink control area regardless of the contract path.

When a schedule is received with a source or sink that is different from that originally specified on the transmission reservation, Entergy will evaluate the change to determine whether or not a change to the POR or POD is required. If a change to the POR or POD is required, the schedule will not be approved. Schedules that change source and/or sink information will be evaluated according to the following criteria:

· If the source (or sink) changes from a first tier control area to another first tier control area, the schedule will be refused.

· If the source (or sink) changes from a first tier control area to a second tier control area, the schedule will be accepted.

· If the source (or sink) changes from a second-tier control area to another second-tier control area, the schedule will be accepted.

· If the source (or sink) changes from a second-tier control area to a first tier control area that is also the POR (or POD) control area on the reservation, the schedule will be accepted.

· If the source (or sink) changes from a second-tier control area to a first-tier control area other than the POR (or POD) control area on the reservation, the schedule will be refused.

· If the source (or sink) changes from a first or second tier control area to a bus within the Entergy control area, the schedule will be refused.

· If the source (or sink) changes from a bus within the Entergy control area to a first or second tier control area, the schedule will be refused.

· If the source (or sink) changes from a bus within the Entergy control area to a different bus within the Entergy control area, the schedule will be refused.

D. Renewals

Entergy will only accept reservations with a request type of RENEWAL for requests to rollover existing yearly transmission service.  Requests for renewal will not be restudied subject to the following:

1. If a customer seeking to exercise its rollover rights under Section 2.2 of the Entergy Tariff designates additional or different resources for its continuing service (i.e., when a customer seeks to designate additional or different resources or loads than are designated under the existing contract for service), the granting of the requested service will be subject to the availability of transmission capacity on the Entergy transmission system. If the change in resources or loads substantially changes power flows on the Entergy transmission system, the customer’s right to continue taking service may be affected by transmission constraints. 

1. If no capacity exists to accommodate the transmission service requested during the exercise of a rollover right where such request designates additional or different resources, the rollover request will be subject to the results of a System Impact Study to determine whether the change in resources or loads “substantially changes” power flows on the Entergy transmission system.

2. The results of any System Impact Study performed shall indicate the customer’s right to continue taking service, i.e., the customer’s right to renew or rollover its service.

2. To determine whether a change in receipt or delivery points (Network Resources/Network Loads) results in substantial change in power flows on the Entergy transmission system, the Independent Coordinator of Transmission will perform a System Impact Study to determine whether (a) the change causes a constraint on the Entergy transmission system or an increase in power flows (relative to the power flows without the changed receipt or delivery point) over a previously-identified constrained facility and (b) the pre-contingent or post-contingent flows associated with the change have at least a three percent transfer distribution factor/outage transfer distribution factor, respectively over the constrained facility.  If so, Entergy will perform a Facilities Study in accordance with the Entergy Tariff.

1. Rollover requests that are determined to result in a substantial change in power flows on the Entergy transmission system will be evaluated as if the request is a “New Request.”  All studies will be performed in accordance with Entergy’s Tariff and the “New Request’s” queue position.

2. All studies performed are performed in accordance with Entergy’s Tariff and at the customer’s cost.

3. A substantial change is indicated when (a) the change causes a constraint on the Entergy transmission system or an increase in power flows (relative to the power flows without the changed receipt or delivery point) over a previously-identified constrained facility or (b) the pre-contingent or post-contingent flows associated with the change have at least a three percent transfer distribution factor/outage transfer distribution factor, respectively over the constrained facility.

1. Determination of a “substantial change” will result in the performance of a Facilities Study.

E)  Time requirements for submitting schedules

Entergy will accept new schedules up to twenty minutes prior to the start of the schedule instead of 20 minutes prior to the top of the hour.  The following guidelines should be followed for submitting  partial hour schedules.

1. New schedules or schedule changes must be submitted no later than 20 minutes prior to start. New schedules or schedule changes received after the twenty minute deadline will be deemed LATE and will be denied for anything other than emergency reliability reasons.

2. The schedule must be at least 10 minutes in length.

3. The customer must have enough reservation(s) to cover the instantaneous MW amount.  For example, if a customer wishes to schedule 100 MW for 15 minutes, then the reservation must be for 100 MW for at least the entire hour and not for the integrated amount of 25 MWH. 

4. The smallest increment of service that Entergy offers is fixed hourly (starts at the beginning of a clock hour and stops at the end of a clock hour; therefore, if the schedule crosses the hour, the customer must have enough reservation(s) in each hour to cover the instantaneous MW amount.  For  example if a customer wishes to start a 100 MW schedule at 00:45 and end it at 01:15, then the customer must have a reservation for 100 MW for the entire hour ending 1 and the entire hour ending 2.

5. As with any schedule, to the extent neighboring Control Areas are involved, they must also approve the details and timing of the submitted schedule

IX. Network Integration Transmission Service (NITS)

A. General

1. NITS allows Network Customer to integrate, economically dispatch, and regulate its current and planned Network Resources to serve its Native Load in a manner comparable to that in which Entergy utilizes its transmission system to serve its Native Load Customers.

2. Customers may designate a new Network Resource if they submit a request on the OASIS by 12:00 noon CPT on the Business Day prior to the day of service.  The Network Customer must obtain or provide ancillary services.

3. Entergy will plan, construct, operate, and maintain its transmission system in accordance with good utility practice to provide the Network Customer with NITS.

4. The Network Customer is responsible for providing for the 3.0% transmission losses plus a charge for service on Entergy distribution facilities, if applicable and included in the service agreement.

5. A Network Customer can not use NITS for the sale of capacity and energy to non-designated load or for the direct or indirect provision of transmission service by the Network Customer to third parties.

6. NITS prices are not posted on the OASIS.

B. GUIDELINES FOR THE DESIGNATION OF NETWORK RESOURCES

1. These provisions identify the requirements and procedures for designating Network Resources under the NITS provisions contained in Section III of the Entergy Tariff. There are two types of Network Resources: (1) generating facilities the Transmission Customer directly owns or leases; and (2) power purchase contracts that commit the Network Customer to pay for and the Seller to provide non-interruptible power.  The minimum term for which Entergy shall honor a request for designation of Network Resources is the same as the minimum time period for firm point-to-point service (i.e., daily).

2. Requirements for Designating Generating Facilities as Network Resources

1. The Network Customer must attest that the portion of the generating facility’s output to be designated as a Network Resource is:

1. Able to meet Network Load on a non-interruptible basis; and

2. Not “committed for sale to non-designated third party load” within the meaning of Order No. 890.

2. If the generating facility is not directly interconnected with the Entergy transmission system, the Network Customer is responsible to ensure that firm transmission arrangements are established from the generating facility to a point of delivery on the Entergy transmission system.  The Transmission Provider is responsible to verify the firmness of such arrangements.

1. The one exception to this requirement is a generating facility in place under a firm agreement as a Network Resource prior to Order No. 888.

3. If the generating facility is not directly interconnected with the Entergy transmission system, the MW amount designated as a Network Resource may not exceed the MW amount of the customer's firm rights that qualify as a Network Resource and all other requirements for off-system Network Resources must be satisfied.

4. All other requirements for off-system Network Resources must be satisfied as detailed in Section III of the Entergy Tariff

3. Requirements for Designating Power Purchase Contracts as Network Resources

1. A power purchase contract (or a similar contract entitlement to the output of a generating facility that is not owned or leased by the Network Customer) may be designated as a Network Resource as long as the contract satisfies the following:

1. The power purchase being designated must be pursuant to (i) an executed contract or (ii) a contract the execution of which is contingent upon the availability of transmission service.

2. The power purchase must be a firm power purchase that allows for interruption only for reliability reasons, not economic reasons. A contract for the sale of non-firm or general-purpose energy does not qualify for designation as a Network Resource under the Entergy Tariff.

3. The contract must commit the Network Customer to pay for the purchase. A contract that enables the customer to avoid the financial consequences for failure to purchase the power does not qualify for designation as a Network Resource. 

1. A "Liquidated Damages" contract qualifies as a Network Resource if the contract is a firm energy purchase that specifically requires the seller to pay the buyer’s cost of replacement power if the firm purchase is interrupted for any reason other than force majeure (“make whole provision”).  Any contract which contains any unacceptable Liquidated Damages provision, but otherwise qualifies for designation as a Network Resource and was properly designated as a Network Resource prior to the effective date of Order 890  will be grandfathered until the earlier of:

1. The expiration of the current term of the power purchase agreement; or

2. An indefinite termination of the power purchase agreement as a designated Network Resource pursuant to section 30.3 of the pro forma Tariff.

2. A “Seller’s Choice” contract qualifies as a Network Resource if the generating units from which the power will be sourced are external to Entergy’s transmission system and all information required to be provided under Sections 29.2 and 30 of Entergy’s Tariff are provided.

4. All other requirements for Network Resources as set forth in Part III of the Entergy Tariff, FERC Order No. 890, FERC Order 890-A, and any other applicable requirement. 

2. Firm point-to-point transmission service provided on a conditional firm basis is sufficiently firm to be used for transmission to import a designated Network Resource provided that it is not interruptible for economic reasons and that it does not originate within the control area within which it is to be designated.

3. If the purchased power is not directly interconnected with the Entergy transmission system, the MW amount designated as a Network Resource may not exceed the MW amount of the Network Customer's firm rights that qualify as a Network Resource.

4. All other requirements for off-system Network Resources must be satisfied as detailed in Section III of the Entergy Tariff.

4. Identifying the Location of Network Resources

1. If a Transmission Customer owns or has obtained firm rights to generation that is located outside of the Entergy control area and beyond the Entergy transmission system that it desires to designate as a Network Resource, and those rights otherwise satisfy the requirements for Network Resource designations under Sections 29.2 and 30 of the Entergy Tariff and are consistent with Attachment M to the Entergy Tariff, the Network Customer must identify the individual resources or the control area where the source generating unit is located.

5. Designations of Network Resources Under More Than One Open Access Transmission Tariff 

1. A Network Customer will be permitted to designate a generation resource or a portion of a generation resource as a Network Resource under the Entergy Tariff, even if that Network Resource has been designated as a Network Resource under another transmission provider's Open Access Transmission Tariff, so long as (a) the Network Resources and Network Loads are dispatched and telemetered on a single, integrated basis, and (b) the Network Resource is not dedicated to serve any other firm load or encumbered by any contractual agreements for the sale of firm energy to any third party.

1. The Network Customer will be required to make all arrangements necessary with the other transmission provider to satisfy that other provider's requirements.

6. Information Required for Designating Network Resources

1. Entergy will require all information set forth in Sections 29.2 and 30 of the Entergy Tariff to be provided by the Transmission Customer when designating a Network Resource.

7. Procedures for Designating Network Resources

1. A Transmission Customer seeking to designate Network Resources for the first time should include a list of Network Resources with its application for NITS pursuant to Sections 29.2 and 30 of the Entergy Tariff.

2. All requests to designate new Network Resources must be made over OASIS pursuant to Section 29 of the Entergy Tariff. Although Entergy will consider Network Resource designations that are submitted prior to 12:00 noon CPT on the Business Day prior to the day of service, Network Resource designations should be submitted as soon as practicable to ensure that the requests can be evaluated in time to allow commencement of service.

3. All OASIS requests shall be accompanied by the following attestation, which should be provided in accordance with Section XV, Interim Business Practice Governing Attestation Requirements for Network Resource Designations Under ORDER NO. 890:

1. “(1) The Network Customer owns the resource, has committed to purchase generation pursuant to an executed contract, or has committed to purchase generation where execution of a contract is contingent upon the availability of transmission service under Part III of the Tariff; and (2) The Network Resources do not include any resources, or any portion thereof, that are committed for sale to non-designated third party load or otherwise cannot be called upon to meet the Network Customer’s Network Load on a non-interruptible basis.”

4. Requests for designation of Network Resource will be acknowledged within 10 days of receipt and will evaluate whether there is sufficient AFC to accommodate each such request within 30 days of receipt. If AFC is insufficient to accommodate any request, Entergy will apply the System Impact Study procedures described in Section 32 of the Tariff.

8. Customer Confirmation Time Limits for OASIS Requests by Service Increment

Service Type	Confirmation Time Limit
Yearly Firm	15 days
Monthly Firm	4 days
Weekly Firm	24 hours
Daily Firm (submitted more than 24 hours in advance)	24 hours
Daily Firm (submitted less than 24 hours in advance)	2 hours
Network Resource granted under a System Impact Study	15 days

9. Use of Non-Qualifying Secondary Resources

1. Generating facilities or power purchase contracts that do not qualify as Network Resources under the criteria listed above may nevertheless be used to serve Network Load on a non-firm basis, under the secondary service provisions of Section 28.4 of the Entergy Tariff.

XII. Prepayment of Service

Effective Date:  For OASIS reservations with a start of service date on or after June 1, 2004.

1. This Business Practice provides implementation details for the prepayment provisions for a new transmission customer and an existing transmission customer per Section 11.3 of Entergy’s OATT. 

2. A minimum of 30 days notice of the election of prepayment status is required, and the election must be made on a calendar month basis.  Upon election of prepayment status, the transmission customer must immediately provide to Entergy Services Transmission Services group a phone number, a fax number, a primary contact name, and an email address in order to facilitate the necessary rapid exchange of invoice data and remittance of funds.  Any outstanding transmission service charges, including charges for the current month’s service, will be invoiced at the end of the current month pursuant to the normal transmission service customer billing cycle.  These charges must be paid by the due date, which will be the earlier of the normally calculated due date or 5 business days prior to the beginning of the next month.

3. This prepayment process assumes a valid OASIS request is one that has been approved by the Transmission Provider (TP) and confirmed by the Prepayment Transmission Customer (PPTC).

4. By virtue of the inherent nature of Daily Non-firm and Hourly Non-firm service, Entergy is unable to accommodate these types of service under the FERC approved prepayment provisions.

5. A Business Day is defined as one which is recognized by the Federal Reserve Bank as an operational day and excludes weekends and holidays as defined by the Federal Reserve Bank.  On each business day, the TP will identify all confirmed reservations from PPTCs through the end of the prior calendar day, generate invoices, and transmit the invoices to the PPTC by fax and/or email. A separate invoice will be generated for each confirmed OASIS reservation.

6. For reservations of a month or less, the invoice due date for prepaid transmission service will be 2 business days following the date of the invoice and no later than 5 business days prior to the start of service for that reservation (i.e., the earlier of 2 business days following the date of the invoice or 5 business days prior to the start of service for that reservation). 

7. For reservations greater than a month, the invoice due date for the initial month of prepaid transmission service will be 2 business days following the date of the invoice and no later than 5 business days prior to the start of service for that reservation (i.e., the earlier of 2 business days following the date of the invoice or 5 business days prior to the start of service for that reservation).  For subsequent months, the invoice due date will be 5 business days prior to the beginning of each month.

Following is a time line showing the invoice date (Inv Dt) and invoice due dates (Inv Due Dt) for reservations confirmed on each day from May 17th, 2004 through May 23rd, 2004 all with a start-of-service (SOS) date of June 1, 2004

(1):  Note that Monday, May 24, 2004 is the 5th business day prior to SOS for OASIS reservations with SOS = June 1, 2004.  Note also in this example, Sunday, May 23, 2004 is the final calendar day on which the PPTC may confirm an OASIS request with SOS= June 1, 2004

1. If the prepayment is not received by the invoice due date, the reservation will be annulled.  In order to assure accurate and timely recognition by Entergy of payments, the Entergy invoice number must be referenced on the payment. 

2. Payments made after the reservation has been annulled will be refunded. No interest will be included with refunds of payments made after the due date.

3. Prepayment invoices will reflect an estimated charge for Ancillary Services Schedules 1 and 2. Variance between the estimate and actual charges (including any applicable price cap credits, TLR credits, penalties, and interest) will be reconciled at the end of the month during the non-prepayment Point-to-Point transmission service customer billing cycle.

4. Interest on prepayments will be calculated based on 18CFR35.19.a.(a)(2)(iii) from the date payment is received until the earlier of the end date of the reservation or the end of the month. Interest due to the PPTC will be calculated at the end of the month during the non-prepayment Point-to-Point transmission service customer billing cycle.

XIII. Suspension of Service

In accordance with Section 11.4 of Entergy’s Open Access Transmission Tariff (OATT), Entergy may suspend transmission service if the Transmission Customer fails to provide the required financial assurance pursuant to Section 11.3.3 or 11.3.4. 

1. The Transmission Customer will be notified in accordance with Section 11.3.5. of its obligation to provide financial assurance and the required deadline to provide this financial assurance. Failure to meet these noticed deadlines will result in the suspension of service.

2. Suspension of service means all confirmed reservations will be Recalled. All new reservations submitted by suspended customer will be rejected until its financial assurance requirements are met. 

Entergy will manage suspension of service on a weekly basis to allow the suspended capacity to be returned to the market. This means that if service is suspended on or after Monday of the week, the reservation will not be restored until the next Monday following the time the Transmission Customer’s financial assurance requirements are met.

1. Reservations for a week or less will be Recalled upon suspension of service and returned to the market

2. Reservations of greater than a week will be Recalled for the balance of the current week and on a weekly basis until the Transmission Customer provides the required financial assurance.

2. Entergy will not restore the capacity to the Customer within the week of suspension. The Transmission Customer must make a new OASIS request after providing the required financial assurance if service is desired during the week of suspension. Entergy will approve the new request only if capacity is available.

The Transmission Customer will not be billed for transmission service that has been suspended for failure to provide the required financial assurance.

XIV. Un-Designating Network Resources

Procedure for Un-designating Network Resources

Ø Reference to Open Access Transmission Tariff

The OATT permits the un-designation of reserved network resources under section:

30.3 Termination of Network Resources—The network customer may terminate the designation of all or part of a generating resource as a Network Resource at any time but should provide notification to the Transmission Provider as soon as is reasonably practical.

Ø Notification Process:

Notification by a network service provider to an employee stationed at the ICT “Next Day” reservation desk by facsimile is entered in OA to release reserved capacity in the amount requested by the customer for a specified interval. The telephone number for the ICT facsimile is included on the attached form.

FAX FORM – For un-designating network resources.

Ø Partial Un-designation of Existing Reservations:

A request by a network provider to reduce an existing reservation to a partial amount of the initial capacity or to reduce the time interval that was initially reserved is identified as a “RECALL” in the OASIS Automation (OA) software. The capacity of a reservation is revised by the amount specified for the time period specified or the duration is revised for the interval specified within the initial reservation time interval as requested by the customer.

Ø Complete Un-designation of Existing Reservations:

If the customer wishes to release the entire reservation, which has not yet started, the transmission provider will change the status of the request to ANNUL.

Ø Valid Sinks for Point to Point Transmission Services:

The current list of valid sinks for point to point customers is posted on the OASIS Webpage at: sinks.html

¨ SMEPA (South Mississippi Electric Power Association) using SMEPA TS1 service

o SMEPA* – SMEPA has a pre-888 agreement with Entergy. For the purposes of terminating a designated network resource, Entergy treats SMEPA as a network customer when they use the SMEPA TS1 service. If they use Point-to-Point they are treated just like any other PTP customer.

¨ AECC (Arkansas Electric Cooperatives), using AECC-PCITA service

o AECC has a pre-888 agreement with Entergy. For the purposes of terminating a designated network resource, Entergy treats AECC as a network customer when they use the PCITA service. If they use Point-to-Point they are treated just like any other PTP customer
