1. PROJECT SUMMARY 1.1. Background and Project Need
The purpose of this Facilities Study is to determine the availability of transfer capability across Entergy’s transmission system from Entergy (EES) to American Electric Power West (CSWS) to evaluate the ETEC request for 75MW of yearly network transmission service. The time period for this transfer is from 1/1/2015 until 1/1/2020. The direction of the transaction is EES to CSWS. The study was performed on the latest available 2014-2020 winter, 2014-2020 summer peak seasonal models using PSS/E and MUST software by PTI. The Facilities Study identifies any transmission constraints resulting from the requested power transfer. The Facilities Study also includes cost estimates to correct any transmission constraints.
1.2. Scope Summary
The Facilities Study has identified some transmission constraints. The constraints can be addressed in the following manner:
1.2.1 Upgrade the Cedar Hill-Plantation 138 kV transmission line
The Cedar Hill-Plantation 138 kV transmission line overloads for the loss of the Porter-Oak Ridge 138 kV transmission line. The Cedar Hill-Plantation 138 kV transmission line needs to have a capacity of 291 or greater on all components. The equipment at Plantation needs to be upgraded to increase the rating of the transmission line from 243 MVA to 250 MVA. The upgrade of the Plantation equipment (which increases the line rating to 250 MVA) is proposed in the 2011-2013 Entergy Construction Plan with a 2013 Expected ISD. It is required that the Cedar Hill-Plantation 138 kV transmission line and associated line equipment and bus be upgraded from a capacity of 250 MVA to at least 291 MVA. The proposed upgrade is 467 MVA. The amount of capacity created by this upgrade is 217 MW, and the customer’s use of the capacity created is 4 MW.
1.2.2 Upgrade the Conroe-Plantation 138 kV transmission line
The Conroe-Plantation 138 kV transmission line overloads for the loss of the Porter-Oak Ridge 138 kV transmission line. The Conroe-Plantation 138 kV transmission line needs to have a capacity of 278 MVA or greater on all components.

The equipment at Plantation needs to be upgraded to increase the rating of the transmission line from 243 MVA to 250 MVA. The upgrade of the Plantation equipment (which increases the line rating to 250 MVA) is proposed in the 2011-2013 Entergy Construction Plan with a 2013 Expected ISD.
It is required that the Conroe-Plantation 138 kV transmission line and associated line equipment and bus be upgraded from a capacity of 250 MVA to at least 278 MVA. The proposed upgrade is 291 MVA. The amount of capacity created by this upgrade is 41 MW, and the customer’s use of the capacity created is 4 MW.
1.2.3 CLECO Affected System Study
CLECO has been identified as an affected system. The customer will need to satisfy the requirements deemed necessary by CLECO.
1.2.4 2011-2013 Approved Entergy Construction Plan Projects
The following projects are approved in the 2011-2013 Entergy Construction Plan. These projects are required to be in-service prior to the start of NRIS.
Upgrade equipment at Conroe 138 kV substation – 2011 Expected ISD.
1.2.5 Confirmation of OASIS Request 75821264
In order to grant OASIS Request 75821275, an equivalent amount of the facility’s MW capacity must first be undesignated. The equivalent undesignation request (OASIS 75821264) must, therefore, be confirmed.
The ICT and Entergy agree that pursuant to FERC Order No. 890-A, the disposition of undesignation request OASIS 75821264 is not dependent upon the performance of a Facilities Study. Entergy currently is in the process of modifying its Business Practices. OASIS 75821264 undesignation request will be accepted. The ICT and Entergy are in discussions over the manner of studies that should be performed to assess the reliability impact of requests to undesignate Network Resources.

1.3. Cost Summary
The estimated total project cost is $6,979,570. This cost does not include Tax Gross Up, which may apply. Please note these are 2011 dollars and do not include tax gross-up if and where applicable (Tax Gross Up rate at this time is 25.09 %). Also, note that the estimates include AFUDC and will be removed should the agreement to undertake the project include a prepayment plan. The ICT has assigned $0 as Base Plan upgrades, and $6,979,570, as Supplemental Upgrade based on Attachment T of Entergy’s Open Access Transmission Tariff (“OATT”).
1.4. Schedule Summary The requested in-service date of January 1, 2015 can be met.
2. SAFETY REQUIREMENTS & GENERAL ASSUMPTIONS Safety Safety is a priority with Entergy. Safety will be designed into substations and lines. The designs will be done with the utmost safety for personnel in mind for construction, operation, and maintenance of the equipment. All employees working directly or indirectly for Entergy shall adhere to all rules and regulations outlined within the Entergy Safety manual. Entergy requires safety to be the highest priority for all projects. All Entergy and Contract employees must follow all applicable safe work procedures.
General Assumptions
Sufficient time will be allowed in approving the project, enabling Entergy to prepare a PEP, and be able to complete the project as per schedule, described below. Use of Facilities Study and estimates is not favored to commence an approved project.
Assumptions have been made in developing estimates without performing site visits, surveys, and soil borings. During PEP, these tasks will be completed and could have an impact on estimates and schedule.
All costs above represent good faith estimates in today’s dollars and are based on existing data, and could change considerably after development of detailed execution plan. Price escalation for work in future years has not been included.

3. SCOPE OF WORK 3.1. Cedar Hill to Plantation 138 kV line L886
General Upgrade the line rating from 250 to 291 MVA. Cedar Hill and Plantation Substation ends of the line are determined to be adequate to carry 291 MVA.
Line Data MVA
Required Line Rating (Minimum) 291 MVA
Proposed Line Rating (based on
1272 conductor with 1957A = 467
MVA) rating
467 MVA
Affected line length 2.38 mi.
Background
ETI proposes to eventually upgrade 138 kV L-886 to 230 kV between Tamina and Conroe Bulk Substations in Montgomery County, Texas. This project focuses on the portion between Cedar Hill GOAB to Plantation Substation. The project plan calls for rebuilding the existing single circuit structures with a double circuit structure, with one (1) circuit left vacant for a future circuit expansion. The project lies in Montgomery County (TX 339) – NAD 4203 Central Zone in the State Plane Coordinate system.
Project Description The proposed project will upgrade 2.38 miles of 138 kV Transmission Line 886, and will leave sufficient room on the double circuit structures to construct future 230 kV Transmission Line. Design criteria – LC-2A Zone: under extreme wind 110 mph, NESC medium, and .5” ice. Structures will be designed to accommodate two (2) circuits of 1272 ACSS “Bittern” conductor in a vertical configuration and two (2) three (3) foot shield wire davit arms, per Entergy 230 kV standards.

● Assumption was made that all local permits will be filed 60 days before
start of construction.
● Assumption was made that all Environmental Permits will be approved 60 days before start of Construction.
● Assumption was made that the quantities of materials listed in this document are approximate and could change with completion of detail design.
Relay Settings Relay settings would be revised at Conroe and Tamina Substations to enable 291 MVA through Cedar Hill and Plantation section of line. Construction Outage of Cedar Hill to Plantation line will be required for eight (8) weeks starting September 2013, and since the load at Plantation could be served from Conroe, the probability of getting outage is good. However, due to lack of time in preparing this study, SOC has not been consulted to validate this assumption. Construction will be done using contractor selected through bidding process Wetland, storm water management and other permits will be secured prior to commencing the construction Matting would be used if the ground is wet.

Relay Settings Relay settings would be revised at Conroe and Tamina Substations to enable 291 MVA through Cedar Hill and Plantation section of line. This would meet the requirement for 271 MVA flow through Conroe to Plantation section of line. Switch 16321 at Plantation is rated 1200A (287A) and should be able to withstand 4 MVA overload should the maximum 291 MVA be carried between Conroe and Cedar Hill substations. Construction Outage of Cedar Hill to Plantation line will be required for nine (9) weeks starting November 2013, and since the load at Plantation could be served from Cedar Hill, the probability of getting outage is good. However, due to lack of time in preparing this study, SOC has not been consulted to validate this assumption. Construction will be done using contractor selected through bidding process Wetland, storm water management, and other permits will be secured prior to commencing the construction.

6. SCHEDULE
A detailed schedule will be prepared subsequent to customer approval to proceed with the project. Based on the Task duration schedules listed below, the overall project in-service date is projected to be January, 2015. Based on an assumed customer approval date of April 2013, the following are approximate schedule dates:
Summary: Submit Facilities Study 11/1/2011 Customer + FP/WOs Approval Apr 13 Complete PEP Oct 13 Customer approval + Revised FP approval Nov 13 Commence design/ROW/environmental approvals Dec 13 Order material Feb 14 Issue design for construction & permits for construction Jun 14 Start Construction Sep 14 Complete construction Jan 15
Notes to Duration Schedules:
It is assumed that the outage of line between Cedar Hill to Plantation would be available between September 2013 to the end of October 2013, and the outage of line between Plantation and Conroe will be granted during November 2013 to January 2014.
Pre-existing scheduled line outages may prevent the commencement of work. Scheduled outages cannot be confirmed until a firm construction schedule is submitted.
All construction work requiring outages will be performed during off-peak load season. Line outages will be discussed with the SOC and TOC, and the assumption is made that line outages will be executed, as planned. However, last minute denial of outages by the SOC/TOC along with resulting schedule delay is possible.
Design and Construction resources are available when required.
Different resource is used for each design, so all designs start at same time.
This schedule does not account for adverse weather conditions.
Schedule durations are high level estimates at this time. A detailed schedule will be prepared upon project approval.

****
Storm-water plan implementation
Best guess on SWPPP creation, implementation and monitoring can vary greatly dependant on outcome of environmental study.
**
Weather & Equipment Lead Times (Poles)
Unexpected delays on material lead times, unusually inclement weather will impact schedule but might impact indirect and AFUDC costs.
**
Wetland mitigation Undetermined until environmental analysis is complete.
***
Outages may not be available
Preliminary schedule only considers general outage constraints. Specific project schedule may be delayed by days, weeks or months dependant on system conditions. Delays of months = increased project costs.
**
Rural road conditions/ County requirements
Depending on the condition of the dirt road, additional matting may be needed or mitigation of overhead obstructions. Possible permit requirement or repairing the road.
**
Scope based on design assumptions which may change
Varied impact on cost and schedule. ***
*-low impact to cost, ** - moderate impact to cost, ***- high impact to cost, **** - very high impact to cost.
