LONG DESCRIPTION:  On May 1, 2014, ERCOT will implement Nodal Protocol Revision Request (NPRR) 590, Inclusion of WSL in the Default Uplift Invoice Allocation, which was approved by the ERCOT Board on April 8, 2014.

This NPRR also requires ERCOT to post the Maximum MWh Activity Total (MMATOT) value calculated using data from the previous month by the 15th day of each month to a new Market Information System (MIS)  report.  The report posting shall include:

(a)       The MMATOT as defined in paragraph (2) of Section 9.19.1, Default Uplift Invoices, with the exception that the calculation shall use Initial Settlement data for each Operating Day in the month prior to the month of the posting.

(b)       The month of the data used in the calculation of the MMATOT.
This new Public report will be posted on the MIS on the Markets, Settlements landing page, in the Settlements Reports and Extracts (Public) portlet<https://mis.ercot.com/pps/tibco/mis/Pages/Market+Information/Settlements>.
