NPRR200  MMS DC Tie Schedule Data Source

Approved sponsor ERCOT posted 2009-11-30 ercot.com
ReasonThe DC Tie Schedule submission required by the Protocols is redundant as ERCOT already has access to the required information through the Open Access Technology International, Inc. (OATI) database. The requirement for the Qualified Scheduling Entity (QSE) to also submit the DC Tie information through the MMS interface is not needed and creates the possibility that the DC Tie Schedule used by MMS may not be synchronized with the e-Tag information in the OATI database. To avoid this possibility, MMS can be modified to use the OATI database information without the additional requirement to submit through the MMS interface.
