Summary
The M1a component of the Total Potential Exposure (TPE) calculation sets a time period meant to reflect the number of days between an Operating Day and the initiation of a Mass Transition of the Market Participant’s Electric Service Identifiers (ESI IDs) (Mass Transition days are reflected in the M1b component). This Nodal Protocol Revision Request (NPRR) replaces the existing fixed value of M1a with a value that can vary based on non-Bank Business Days and ERCOT holidays following the specific Operating Day.
