    Notice Text:

    In response to customer feedback, Southern Natural Gas Company, L.L.C.  has improved EPSQ warning messages to provide clarity into off-system supply, off-system market activity, and/or net positions at EPSQ-restricted meters.

    Effective November 2, 2026, please note the following enhancements:

    Meters Held to EPSQ by the Pipeline

    Shippers will now receive warning messages displaying:

    ·         Total Off-System Supply

    ·         Total Off-System Market

    ·         Net Off-System Position

    The net value will reflect the total EPSQ as calculated by taking the difference between total off-system supply and total off-system market nominations at the meter.

    Meters Held to EPSQ by Other Operators

    Shippers will continue to receive the existing line-item level Off-System Supply and/or Off-System Market warning messages. In addition, a Net Off-System Position warning message will also be displayed when both supply and market nominations exist at the meter.

    If you have any questions regarding these changes, please contact your Scheduling Representative.
