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 139 MW of yearly network transmission service. The time period for this transfer is from 1/1/2013 until 1/1/2022. The direction of the transaction is EES to EES. The study was performed on the latest available April 2013-November 2014 monthly models, 2014-2024 winter, and 2015-2024 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. ATC is not available from 1/1/2013-1/1/2015. The following constraints are identified from 1/1/2013-1/1/2015.

Limiting Element Contingency Element

Nelson 500/230 kV autotransformer Cypress-Hartburg 500 kV

Waterford-Little Gypsy 230 kV ckt #1 Waterford-Little Gypsy 230 kV ckt #2

Waterford-Little Gypsy 230 kV ckt #2 Waterford-Little Gypsy 230 kV ckt #1

For ATC beyond 1/1/2015, the following upgrade is required.

1.2.1 Upgrade the PPG-Rose Bluff 230 kV transmission line

The PPG-Rose Bluff 230 kV transmission line overloads for the loss of the Carlyss-Nelson 230 kV transmission line. It is required that the PPG-Rose Bluff 230 kV transmission line be upgraded from a capacity of 470 MVA to at least 527 MVA. The proposed upgrade rating is 595MVA.

The PPG-Rose Bluff 230 kV transmission line upgrade has been identified as a Supplemental Upgrade project in previous facility studies (OASIS request number 76523750 and 76523753) with an expected in-service date of 2015. However, the proposed upgrade capacity for those requests was 519 MVA. If the proposed line upgrade is committed to by the prior customer, the customer submitting this transmission service request would be responsible for the incremental cost to upgrade the conductor from 519 MVA to at least 527 MVA.


Page 4 of 23

The amount of capacity created by this upgrade is 76MW, and the customer’s use of the capacity created is 0MW.

If the PPG-Rose Bluff 230 kV transmission line upgrade and associated transmission service requests are withdrawn by the previous customer, the customer submitting this transmission service request would be responsible for funding this upgrade from the original capacity of 470 MVA to meet the required capacity of 527 MVA.

The amount of capacity created by this upgrade is 125MW, and the customer’s use of the capacity created is 4MW.

1.2.2 Financial Rights for Supplemental Upgrades

The following Supplemental Upgrade is impacted by this TSR by the specified MW amount.

Hartburg-Inland Orange 230kV Line – 10 MW Impact o Estimated Unit Rate - $31,821/MW o Financial Rights - $318,210 ($31,821 x 10 MW) o Related Facilities Study – OASIS 1598291

If the PPG-Rose Bluff 230 kV transmission line upgrade is committed to by the previous customer (OASIS request number 76523750 and 76523753), the customer submitting this transmission service request would be responsible for payment of Financial Rights for the following Supplemental Upgrade.

PPG-Rose Bluff 230kV Line – 4 MW Impact o Estimated Unit Rate - $74,340/MW o Financial Rights - $297,360 ($74,340 x 4 MW) o Related Facilities Studies – OASIS 76523750 and 76523753

Rollover rights are available.

1.2.3 Relay Settings

Revise settings as needed on both ends at PPG and Rose Bluff to cater the extra Amperes upgrade.

1.3 Cost Summary

The estimated total project cost in 2013 dollars is $4,541,943. This cost does not include Tax Gross Up which may apply. Please note these are 2013 dollars and do not include tax gross-up if and where applicable


Page 5 of 23

The ICT has assigned $0 as Base Case upgrades and $$4,541,943 as Supplemental Upgrade based on Attachment T of Entergy’s Open Access Transmission Tariff (“OATT”)(OATT).

Financial Rights: As described in Section 1.2.2 above, either $318,210 or $615,570 in financial rights payment will be required to the customer funding the supplemental upgrade that was impacted by this transmission request. The cost does not include Tax Gross Up, which may be included.

1.4 Schedule Summary

The requested date for the start of network transfer is January 1, 2013. This date will not be met and based on Entergy project schedules, the upgrades will be completed by December 1, 2014 assuming proposed outages are granted.

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.

3. GENERAL ASSUMPTIONS:

Sufficient time will be allowed in approving the project enabling Entergy to prepare a Project Execution Plan and be able to complete the project as per outlined in the schedule described provided below.

Assumptions have been made in developing estimates without performing site visits, surveys, and soil borings. During Project Execution Plan these tasks will be completed and could have an impact on estimates and schedule.

All costs above represent good faith estimates and are based on existing data and could change considerably after development of a detailed project execution plan. Price escalation has been included in the estimate.

Relay settings and RTU configurations Details need to be specified during Project Execution (PEP) Plan stage, such as equipment and schemes for pilot protections.

System changes will be modeled in ASPEN. Relay Impact Analysis will be performed by a settings engineer during PEP stage to identify requirements for relay/CT replacement and settings revisions at the local and remote stations in the area. For example, affected elements include Z2, Z3, and


Page 6 of 23

ground over current settings, and so on. Some obsolete relays may need to be replaced

Communicate the project and protection coordination with nuclear, generation plants, load customers and other interconnected utilities as appropriate

Comply with PRC-001, PRC-023 and relevant procedures, standards and guidelines as appropriate

New RTU configurations or revisions may be necessary for stations where new equipment is installed or equipment replacement takes place. For example, there may be a need to map the additional points from a new or different relay.

Relay Settings:

Relay settings will be revised at each end of the line to accommodate new line conductor size and the new line rating. In addition, remote ends may also need to be adjusted to accommodate this change in terms of zone 2 and zone 3 line relay settings.

Construction Methodology

This is an existing Right of Way, so no vegetation clearing is expected. Storm water controls will be installed before work begins and monitored throughout the project. Foundation work will be first by driving the vibratory caissons and backfilling with concrete. These will be allowed to cure for a minimum of 7 days. The tangent poles can be set while the foundations are curing. All structures will be set and framed out with dollying in place in preparation for wire pulling. Conductor and fiber will be pulled in and clipped and the drop into PPG substation secured as well as attaching to structure #36.

Outage Planning The TOC will be asked to evaluate the outage availability of L-696 to determine if we can open the 230kV loop for an extended period or if we will need to work this line as piece work doing one section at a time. The schedule proposes two separate outages to complete this work. TOP felt that the following outages have good likelihood of getting approved: 1) 1 Sept – 15 Oct 2014 – 6 weeks 2) 1 Nov – 15 Dec 2014 – 6 weeks Safety consideration and risks during construction Follow all Entergy and OSHA rules including EPZ and Grounding requirements as well as clearance rules. An Entergy Operations Coordinator will be on site for a majority of the project.
