KEY REFERENCES (Non-Entergy): 
#1. North American Electric Reliability Corporation (NERC) Standard  FAC-001-3. Link:

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 interconnection 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.
