This Nodal Protocol Revision Request (NPRR) removes a redundant requirement for ERCOT to produce a report regarding Electrical Bus changes.
The reporting requirement in paragraph (2) of Section 3.5.1 is a redundant posting of similar information required by Section 184.108.40.206, Posting of Hub Buses and Electrical Buses included in Hubs. A report of differences is posted on the Market Information System (MIS) Secure Area after every model load and includes a list of all Electrical Bus changes.
The Market Management System (MMS) automatically uses only the currently energized Electrical Buses to calculate the Hub price. These price calculation modifications are done in Real-Time without user interaction.
