    Welcome to Southern Company's OASIS Node


    Delay in Filing of 2015 OATT and Attachment U True-Up Filings

    As discussed in a filing made with FERC today, Southern Companies filings of its 2015 OATT and Attachment U True-Up Filings are being delayed until on or before June 1, 2016 due to Mississippi Power Company being granted by FERC an extension of time to file its 2015 FERC Form No. 1. Pursuant to Southern Companies OATT, all other schedules associated with the 2015 true-up filings will also be delayed.


    Updated Tariff Rates Effective Jan 1, 2016

    Please refer to the Tariff Rate Summary sheet on the Tariff Rates (Open Access Transmission Tariff-->Tariff Rates) page to review the updated charges for OATT service that will take effect on January 1, 2016.

    Due to an error in processing a small number of TSRs were allowed to redirect on a non-firm basis to Hourly Non-Firm Point to Point on Southern's OASIS. We have corrected this issue and apologize for any confusion it may have caused. All redirects on a non-firm basis will only be allowed on the Hourly Secondary Point to Point service.
