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 Entergy (EES) to evaluate the Entergy Services (SPO) request for 9 MW of yearly network transmission service. The time period for this transfer is from 1/1/2013 until 1/1/2033. The direction of the transaction is EES to EES. The study was performed on the latest available January 2013 – May 2014 monthly models, 2014-2023 winter and 2014-2023 summer peak seasonal models using PSS/E and MUST software by Power Technologies Incorporated (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.

Rollover rights are available.

The following project is required to be in-service prior to 1/1/2019 for ATC to be available.

1.2.1. Construct a new China – Amelia 230 kV line

The China – Amelia 230 kV transmission line overloads for the loss of the China – Amelia 230 kV transmission line. Also, the China – Amelia 230 kV transmission line overloads for the loss of the China-Amelia 230 kV transmission line. A second 230 kV transmission line from China to Amelia will alleviate these constraints. This project is proposed in the 2012-2016 Entergy Construction Plan with an expected ISD of Summer 2016.

1.3. Cost Summary

The estimated total project cost is $36,642,178. This includes AFUDC and does not include Tax Gross Up which may apply if and where applicable (Tax Gross Up rate at this time is 24.85%). The estimate includes AFUDC and it will be waived should customer elect to make prepayment The ICT has assigned $36,642,178 as Base Plan upgrades and $0 as Supplemental Upgrade based on Attachment T of Entergy’s Open Access Transmission Tariff (“OATT”).

4.3. New 230 kV Line between China to Amelia

Line Data MVA Required Line Rating (Minimum) 1957A Proposed Line Rating (based on Equipment to be installed) 1957A

Affected line length 11 miles

Build a new 230 kV line, approximately 11 miles long with a proposed route north from China along existing China – Jacinto 230 kV line 568 for approximately 2.5 miles, then east to Amelia. ROW

Approximately 11 miles of 100’ wide new Right of Way, or approximately 133 acres, would be required. It would take approximately 12-18 months to acquire this Right of Way. Three (3) permits would be required to cross LNVA (Lower Neches Valley Authority) freshwater canals. It will take an estimated 1-3 months to finalize the permits once the crossing permit drawings are finalized. One (1) railroad crossing permit will be required. It will take an estimated three (3) months to finalize the permit once the crossing permit drawing is finalized. No state or federal highway crossing permits are anticipated. Environmental

The following Permits / Studies will be required:

• Wetland Delineation and Phase I ESA (Environmental Site Assessment) Screen • Wetland Permits • Phase I Cultural Resources Review • USFWS (US Fish and Wildlife Service)Threatened and Endangered Species



13

Line route The proposed line route runs north from China Substation along existing 230kV L-568 (China – Jacinto) for approximately 2.5 miles, then runs east to Amelia for a total run of approximately 11 miles.

Structures and Foundations It is estimated that this project will require eight (8) single-pole baseplated steel dead end structures in drilled pier foundations, 35 single-pole socket steel tangent structures in vibratory pile foundations, and 35 single-pole direct embedded steel tangent structures. A topographic survey and geotechnical studies would be required in order to perform a detailed design of structures and foundations. Conductor and Insulators 1272 ACSS “Bittern” conductor has been used to develop this estimate. This conductor can supply 1957 Amps at 347ºF. Approximately 261,621 lbs of conductor would be required to complete the 22 mile job. It is estimated that 54 polymer dead end, 210 2.5” polymer braced post, and 15 polymer jumper line post insulator assemblies would be required for this project. OPGW Entergy standard 48-fiber -0.528” Alumacore OPGW will be installed as the primary shield wire for this project. Approximately 61,000’ of cable and three (3) splice boxes would be required. Shield Wire 7#7 Alumoweld would be used as the secondary shield wire in areas where it is required, such as the last span into the substations on each end of the line. A small amount of this cable has been assumed in the estimate. Long Delivery Items
