LONG DESCRIPTION: On September 23, 2015, ERCOT will implement Nodal Protocol Revision Request (NPRR) 589, Ancillary Service Offers in the Supplemental Ancillary Services Market and NPRR701, As-Built Clarification for NPRR589.
o Settlements impact include the following changes:
6.7.2 Charges for Ancillary Service Capacity Replaced Due to Failure to Provide
1. Reconfiguration Reg-Up Failed Qty Amount:
RRUFQAMT q = MCPCRU rs * RRUFQ q, rs
QSE Total:
RUFQAMTQSETOT q = RUFQAMT q + RRUFQAMT q
2. Reconfiguration Reg-Down Failed Qty Amount:
RRDFQAMT q = MCPCRD rs * RRDFQ q, rs
QSE Total:
RDFQAMTQSETOT q = RDFQAMT q + RRDFQAMT q
3. Reconfiguration Responsive Reserve Failed Qty Amount:
RRRFQAMT q = MCPCRR rs * RRRFQ q, rs
QSE Total:
RRFQAMTQSETOT q = RRFQAMT q + RRRFQAMT q
4. Reconfiguration Non-Spin Failed Qty Amount:
RNSFQAMT q = MCPCNS rs * RNSFQ q, rs
QSE Total:
NSFQAMTQSETOT q = NSFQAMT q + RNSFQAMT q
o Settlement Calculation Revisions:
6.7.3 Adjustments to Cost Allocations for Ancillary Services Procurement
1. Reg-Up Obligation per QSE
RUO q = [cid:image002.png@01D0EBBE.75B08280] (SARUQ q + [cid:image004.png@01D0EBBE.75B08280] (RTPCRU q, m) + PCRU q - RURP q - RUFQ q - RRUFQ q) * HLRS q + RURP q
2. Reg-Down Obligation per QSE
RDO q = [cid:image002.png@01D0EBBE.75B08280] (SARDQ q + [cid:image004.png@01D0EBBE.75B08280] (RTPCRD q, m) + PCRD q - RDRP q - RDFQ q - RRDFQ q) * HLRS q + RDRP q
3. Responsive Reserve Obligation per QSE
RRO q = [cid:image002.png@01D0EBBE.75B08280] (SARRQq + [cid:image004.png@01D0EBBE.75B08280] (RTPCRR q, m) + PCRR q - RRRP q - RRFQ q - RRRFQ q) * HLRS q + RRRP q
4. Non-Spin Obligation per QSE
NSO q = [cid:image002.png@01D0EBBE.75B08280] (SANSQ q + [cid:image004.png@01D0EBBE.75B08280] (RTPCNS q, m) + PCNS q - NSRP q - NSFQ q - RNSFQ q) * HLRS q + NSRP q
o New Settlement Bill Determinants:
The following bill determinants will be implemented for NPRR589 and NPRR701 (As-Built Clarification for NPRR589):
