Reason For Revision
The market priority type of Day Ahead Economic (DAECON) indicates a Day Ahead award of lower priority determined economically in the Day Ahead market.  Since the DAECON market type is replaced with either RTLPT or RTECON in HASP, it would require Scheduling Coordinators modify the E-tag market priority type after HASP.  Removing the DAECON market priority type eliminates the need to re-tag.

Correction: 

Previously the CAISO required market priority types of DALPT and DAECON to be tagged separately, which indicated a Day Ahead award of lower priority determined economically in the Day Ahead market.  We have eliminated the tagging requirement of DAECON since the DAECON market type is replaced with DALPT in HASP. DAECON market awards should be tagged as DALPT. Combining those DA tagging requirements in to one market priority relieves the Scheduling Coordinators of having to modify the E-tag market priority type after HASP.

Just to clarify and answer questions, this change does not affect the Day Ahead market awarding of DAECON.  This is only focused on the Tagging requirement.  Without this change (and per the requirement to add the Market Priority Type to tags), an SC would be required to initially tag the award in the Day Ahead timeframe as DAECON, and subsequently after HASP re-edit every tag to RTECON.  Instead, (and with this change) tagging as DALPT opposed to DAECON removes this extra burden.  As this is a tagging change only, the BPM section on Day Ahead Tagging requirements should be suffice documentation on this change.

Notes:
Initial Comments
The CAISO has received written comments from Amber Clinkscales at SRP:

SRP appreciates the opportunity to comment on PRR 1533. SRP requests that the CAISO provide a formal announcement of the change in tagging from DAECON to DALPT.  Previously, Scheduling Coordinators (SCs) were required to tag DA economic bids that cleared RUC as DAECON.  Now, the CAISO is requiring SCs to change the tagging of these awards to DALPT.  This should be clearly noted in the BPM and communicated to participants when this change is taking place.  SRP is also unsure how DAECON was being converted to RTECON or RTLPT in HASP.  This should be clarified as well.

Recommendation Comments
The CAISO received written comments from Amber Clinkscales at SRP:

SRP recommends that the CAISO review the language regarding DAECON being converted to RTECON or RTLPT in HASP.  DAECON is converted to DALPT in real time.
