Entergy Facility Connection Requirements

Revised October 29, 2018

#1. North American Electric Reliability Corporation (NERC) Standard  FAC-001-0  April 1, 2005. Link: FAC-001-2 or navigate to the NERC Corporation web site in a path such as http://www.nerc.net/standardsreports/standardssummary.aspx.

#2. SERC Reliability Corporation (SERC) Guideline: Facility Connection Requirements (SERC regional supplement to the NERC Reliability Standard FAC-001), Oct. 18, 2012, Revision 7.  Link: SERC Supplement Facility Connection Requirement or navigate to the SERC website and search on the "Documents" page.

This web site and the documents it refers to serve as a reference to parties (Connecting Customers) that are either considering connecting to or modifying facilities that are already connected to the Entergy Transmission system.  Transmission consists of lines and facilities operated at or above the transmission voltage level of 69 kV (69,000 Volts).  This scope of the facilities covered are:   Generation facilities Transmission facilities End-user facilities (only those connecting at or above 69 kV)  

The North American Electric Reliability Corporation (NERC) standard and its companion SERC Reliability Corporation (SERC, which was formerly named the Southeast Electric Reliability Council) Supplement referenced above as Key References #1 and #2 require Entergy, as a Transmission Owner, to publish facility connection requirements.  This web site and the documents it links to and confidential documents it refers to are designed to fulfill the publication requirements and provide access to the facility connection requirements.

Entergy has prepared this web site, a text document and a spreadsheet which fulfill the requirements of Key References #1 and #2.  Because the SERC Supplement, Key Reference #2, contains more detailed requirements and has assembled them in a manner different from the NERC Standard, Entergy has chosen to format and address the text and spreadsheet documents in the order presented in the SERC Supplement.  Key Reference #2 therefore can be compared side-by-side to Entergy’s main text and spreadsheet documents. 

These two are:  

Initial contact for interconnections should be made to Entergy’s Transmission Project Development group, either to the Manager or to a local representative.  Access to documents that are deemed confidential is available to parties with a need to know who agree to abide by and sign appropriate confidentiality agreements.

The Generation reader should be aware that, although the NERC Standard FAC-001-0 is applicable only to the FERC functional entity “Transmission Owner,” as written in section 4.1., there are specific requirements contained in the SERC Supplement, Key Reference #2, which apply solely to Generation Owners/Operators.  For example, see the last two paragraphs of its Appendix 2, SERC Power System Stabilizer Guideline.   Furthermore, there are numerous connection requirements covered in the referenced documents Entergy which require compliance on the part of all types of Transmission-connecting facilities.  

SERC, at the time of this writing, has a commitment to review Key Reference #2 every three years.  Therefore a review of the supplement can be expected to be performed by October of 2008.  FERC approved NERC standard FAC-001-0.  It is expected to become effective on or about May 1, 2007 without modification.  To ensure access to the most current versions of these key documents, Connecting Customers should retrieve them directly from the NERC and SERC web sites as indicated in the box above.  

The following statements are declared by Entergy in fulfillment of Key Reference #2, SERC Supplement: Facility Connection Requirements October 13, 2005, Revision 5.  

Reference: Sections II & III.  General Requirements for Compliance 
A Self-Application Statement:

The material contained in the documents which are referenced, or linked, within this  document is consistent in content and application to those requirements used by Entergy Transmission for connecting Entergy and Entergy Affiliated new or modified generation, new or modified transmission, and new or modified end-user facilities.

Other Required Statements:
Entergy’s Facility Connection Requirements comply with all applicable codes, standards, federal and state regulations, environmental regulations, siting requirements, contracts, operating agreements, and FERC tariff requirements.
