o
New bill determinant (OPT); removing bill determinant (DAOPT)
·
Payments for PTP Options with Refund Settled in DAM and No DAM Real-Time Option with Refund Amount
o
New bill determinant (OPTR); removing bill determinant (DAOPTR)
·
Day-Ahead Real-Time Obligation with Links to an Option Amount
o
New bill determinants (OBLLOCRR, RTOBLLO, DARTOBLLOAMT, DARTOBLLOAMTQSETOT, DARTOBLLOAMTTOT)
DARTOBLLOAMT (q, j, k)
= Max (0, DAOBLPR (j, k)) * RTOBLLO (q, j, k)
Where:
DAOBLPR (j, k) = DASPP
k – DASPP j
RTOBLLO (q, j, k) =
OBLLOCRR
q, (j, k), crrid, crrofferid
DARTOBLLOAMTQSETOT q =
DARTOBLLOAMT
(q, j, k)
DARTOBLLOAMTTOT =
DARTOBLLOAMTQSETOT q
·
Real-Time Obligation with Links to an Option Amount
o
New bill determinants (RTOBLLO, RTOBLLOAMT, RTOBLLOAMTQSETOT)
RTOBLLOAMT q, (j, k) = (-1) * Max (0, RTOBLPR
(j, k)) * RTOBLLO q, (j, k)
Where:
RTOBLLOAMTQSETOT q =
RTOBLLOAMT
q, (j, k)
·
Real-Time Revenue Neutrality Allocation
o
New bill determinant (RTOBLLOAMTTOT); removing bill determinants RTOPTAMTTOT and RTOPTRAMTTOT
LARTRNAMT q = (-1) * (RTEIAMTTOT + BLTRAMTTOT + RTDCIMPAMTTOT + RTDCEXPAMTTOT + RTCCAMTTOT + RMRDAESRTVTOT + RTOBLAMTTOT / 4 + RTOBLLOAMTTOT / 4 ) * LRS
q
Where:
RTOBLLOAMTTOT =
RTOBLLOAMTQSETOT
q

On the Market Manager, the Congestion Revenue Right (CRR) Offer displays and labels have been changed to reflect the new name of the similar transaction, PTP Obligation Bid with Links
to an Option. The underlying fields will remain the same. Further, the award report name on the Reports tab has changed, as well.
The implementation of NPRR322 renames the current DAM PTP Obligation and Option Results by Settlement Point report, NP4-194-CD, to DAM PTP Obligation Results by Settlement Point (Report
Type ID 13042). The freeform file name of the report will change from DAMPTPOBLOPTSPNP4194 to DAMPTPOBLSPNP4194, for example:
from
cdr.00013042.0000000000000000.20121106.125940.DAMPTPOBLOPTSPNP4194_xml
cdr.00013042.0000000000000000.20121106.125941.DAMPTPOBLOPTSPNP4194_csv
to
cdr.00013042.0000000000000000.20121206.130154.DAMPTPOBLSPNP4194_xml
cdr.00013042.0000000000000000.20121206.130154.DAMPTPOBLSPNP4194_csv
The report is posted daily and displays on ERCOT.com and the Market Information System (MIS) as follows:

The content of the DAM PTP Obligation Results by Settlement Point report is changing, removing two columns:
·
TOTAL_CRR_NONDAMAWARDED_SOURCE
·
TOTAL_CRR_NONDAMAWARDED_SINK
Existing report columns:
·
DELIVERYDATE
·
HOURENDING
·
STL_PNT
·
TOTAL_PTP_OBL_AWARDED_SOURCE
·
TOTAL_PTP_OBL_AWARDED_SINK
·
TOTAL_CRR_NONDAMAWARDED_SOURCE

The implementation of NPRR322 also eliminates the requirement to post the Real-Time Point-to-Point Option Price Report, NP7-807-CD, (Report Type ID 10043), as redundant data, which
will cease to post on February 13, 2013. The data will roll off (no longer be available) the MIS on March 16, 2013; however, the link for the Real-Time Point-to-Point Option Price report will remain visible on the MIS and ERCOT.com until the second scheduled
system release (R2) of 2013.
