NOTICE DATE: July 13, 2020

NOTICE TYPE: M-A071320-01 Operations

SHORT DESCRIPTION: Implementation of lower Counter-Party (CP) limit for Point-to-Point (PTP) Obligation bids in Day-Ahead Market (DAM)

INTENDED AUDIENCE: ERCOT Market Participants

DAYS AFFECTED: July 13, 2020

LONG DESCRIPTION: ERCOT is lowering the DAM PTP Obligation Bid limit per CP beginning DAM Operating Day July 15, 2020 from 2,000 to 1,500 bid IDs per CP per Operating Day. See Market Notice No. M-B032520-01. System Change Request (SCR) 798, PTP Obligation Bid ID Limit, provides that ERCOT may decrease a CP limit with a Market Notice if the 2,500 bid IDs per Qualified Scheduling Entity (QSE) is unsuccessful at creating appropriate limits for the DAM, and puts a timely DAM solution in jeopardy.

ERCOT is lowering the PTP Obligation Bid limit for CPs due to recent increases in PTP Obligation Bid ID submissions that may create the need for manual DAM intervention, and consequently increases the risk for timely DAM solutions.

The new DAM PTP Obligation Bid limit will be updated on the Market Submission Validation Rules document (EMIL ID: NP4-450-M, Report Type ID: 11457) on the Market Information System (MIS) Secure Area. A Digital Certificate is required to access the MIS. DAM PTP Obligation Bid submissions that exceed the CP limit will receive descriptive rejection messages.
