  1. Nodal EILS Update Mandy Bauld COPS

  2. Topic Refresher • Earlier this year ERCOT brought options regarding the methodology to invoice the EILS payments and charges in Nodal • Options: Miscellaneous Invoice vs. Miscellaneous Debit/Credit line item on a settlement statement • Decision: Use the Miscellaneous Debit/Credit functionality (PUCT requirement to put it on a statement for an Op Day) • Take-Away: ERCOT continue to evaluate possibilities of a more robust solution (that doesn’t require system change) and the possibility of getting EILS data into the settlement extracts

  3. Follow-Up on ERCOT Take-Away • ERCOT has confirmed a data-driven approach that, without system change, will enable the following: • Inclusion of charge types specific to the EILS Payment and the EILS Charge on a settlement statement (instead of as a Miscellaneous Debit or Credit line item) • Inclusion of keyEILS Payment and Charge bill determinants in the settlements extracts • Note: due to the nature of the EILS process, this option is still a manual work-around and therefore there are limitations • Not all of the data elements can be provided; focus remains on the key bill determinants which show QSE’s payment/charge amounts, QSE’s time period LRS, and market totals. • Note: to accomplish this data driven approach, ERCOT needs to used slightly modified bill determinants than what currently show in Protocols

  4. Follow-Up on ERCOT Take-Away • Proposed solution – bill determinants:

  5. Next Steps • Request COPS preference of this option vs. use of Miscellaneous Debit / Credit functionality • Request to take the topic to SEWG to provide more details on the bill determinants and an example • Utilize this approach in upcoming market trials • Use Feb 2010 - May 2010 contract period data • Update the Charge Type Matrix to include EILS settlement • Reflect the bill determinants which will be used by the settlement statements and sent in extracts • ERCOT file an NPRR to address the bill determinant names • Existing Nodal EILS bill determinants do not follow the standards that have been used across other charge type areas (i.e., they look “zonal” not “nodal”) • Update Section 9.5.3 (listing of RTM settlement charge types) to include the EILS charge types
