    Welcome To SC



    Santee Cooper will implement a revised ATCID and TRMID on August 1, 2018. Santee Cooper has still not determined a need for CBM. Each of these revised documents can be viewed from the ATC Information Link.

    Effective August 1, 2018, Santee Cooper will require all deposits for System Impact Studies upon execution of a System Impact Study Agreement.  Previously, as a matter of practice, Santee Cooper would not require the full $50,000 deposit prior to performing a System Impact Study.  Rather, the remaining balance from the $10,000 deposit(s) associated with the Interconnection Request and Feasibility Study, if any, were applied until the funds were exhausted.  This change is due to the increasing number of Interconnection Requests in Santee Cooper’s Queue.

    Questions concerning Next Day business should be directed to (843)761-4079. This number is staffed between the hours of 7:00 AM and 4:30 PM EPT on Monday-Friday. All calls outside of this window should be directed to (843)761-4039. All Questions concerning hourly business should be directed to (843)761-4039
