Urgent: No
Sections: 3.10.4,, 6.3.2,,,,
Description: This NPRR revises how QSEs and TSPs communicate with ERCOT in Real-Time. This Revision Request requires that all Real-Time communications use Inter-Control Center Protocol (ICCP) for all communications. This will retire the existing RTU infrastructure used by ERCOT and its market participants for data exchange. Market transactions using XML and/or MIS, and RTU communications between Market Participants and their field equipment, will remain unchanged.
Reason: A study conducted by ERCOT, with the assistance of KEMA consulting, concluded that the existing RTU technology cannot support the required volume of data in a timely manner. The study also concluded that ICCP is the only technology that can support the data quality requirements.
