I. Firm Transmission Products

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 Fixed 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 If customers fail to take one of these actions, then their requests will be deemed withdrawn and the status on the Entergy OASIS will be changed to “RETRACTED.”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 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 accepted a day ahead of commencement of service, and within 5 minutes for the same day 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 SECONDARY service type,
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 in any service increment less than or equal to the original request increment.

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 - 969 - 4857. 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. An existing Form A-1 governing Short-Term Firm Service, however, cannot be used to take assignment of Non-Firm Transmission Service, and vice-versa. 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 601-969-4838 (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:

1. Login to OASIS using the appropriate OASIS certificate.
2. From the Entergy OASIS home page, select the “Post Reassignment” link.
3. 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.
4. In the “Dates and Times” block, select both start and stop time periods for the service being resold or assigned.
5. 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.
6. In the “Path and POR/POD Information” block, select the same Path or POR and POD as the original TSR.
7. Seller comments can be added to the transaction utilizing the “Seller Comments” field in the “Seller Information” block.
8. After reviewing your entries and selections for accuracy, select the “ADD REASSIGNMENT” button at the bottom of the page.
9. 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.
10. 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.
11. 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,

12. 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
13. 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.
