NOTICE DATE:  January 31, 2013

NOTICE TYPE:  M-A013113-01 NPRR

SHORT DESCRIPTION:  Effective Date details of NPRR461

INTENDED AUDIENCE:  ERCOT Market Participants

DAY AFFECTED:  February 14, 2013

LONG DESCRIPTION:  On January 15, 2013, the ERCOT Board of Directors (Board) modified the Effective Date of Nodal Protocol Revision Request (NPRR) 461, Energy Storage Settlements Consistent with PUCT Project 39917, from “upon system implementation” to “upon implementation of Release 6.”  Therefore, on February 14, 2013, ERCOT will remove the grey-boxes associated with NPRR461 because Release 6 will have been implemented.

Please note that the Board also authorized and approved for ERCOT staff to use a settlement implementation process which utilizes the NPRR461 settlement logic, after system implementation, for any affected Operating Day on or after implementation of “Release 6” and prior to system implementation of NPRR461.  This settlement implementation process will use regularly scheduled Final settlement (“59 day settlement after Operating Day”) and True-Up settlement (“180 day settlement after Operating Day”) to the extent possible, and Resettlement after True-Up if necessary. Given the estimated duration (6 to 9 months) of the project for system implementation of NPRR461, there is potential that a range of 0 to 90 days may require Resettlement after True-Up settlement. ERCOT staff would schedule any necessary Resettlements after True-Up in a manner that helps minimize the impact to resources and invoicing.

ADDITIONAL INFORMATION:  Pursuant to Protocol Section 21.6, Nodal Protocol Revision Implementation, ERCOT is required to provide notice as soon as practicable, but no later than ten days prior to implementation.
