RTCTF,
ERCOT has posted the updated Key Principle documents with revisions for the
next meeting on Sep 19th
(http://www.ercot.com/calendar/2019/9/19/180276-RTCTF). Below is a rather
long summary of the expectations for each of these items, and reminder that
comments/alternative are due a week ahead of time, Thursday Sept 12.
KP 1.1 AS Demand Curves (2) and (5)-
Sep 19th meeting will be the final RTCTF consideration of this item.
* KP 1.1 (2)- Seeking final market comments on concept of maintaining
pricing run to capture the effects of reliability deployments.
* KP 1.1 (5)- Seeking consensus and/or confirming options for TAC
regarding the disaggregation of A/S product curves under the ORDC-shaped
curve.
* ERCOT and Shams will each present KP language and a brief summary of
proposal.
* RTCTF asked for the following to help support this discussion
* Pros/cons for both alternatives
* Examples of impacts for two scenarios (of possible with same data):
* Short duration ramp spike scenario (plenty of capacity, a temporary
ramp constraint)
* Scarcity scenario (similar to August peak demand)
KP 1.2 System-Wide Offer Cap and Power Balance Penalty Price (3)-
Sep 19th meeting will be second meeting to review potential options
for AS Price Caps (MPs need to bring comments/language/options).
* KP1.2 (3)- Method of capping A/S prices

reduction

offer selected)
KP 1.3 Offering and Awarding AS in Real-Time (1)-(12)-
Sep 19th meeting will be an extra meeting to further understand and
review potential options (MPs need to bring comments/language/options).
* KP 1.3 Goal is for any alternatives to be presented as KP language

Offers and Floors
* ERCOT to provide a year of online RRS Gen capacity available and
settlement examples spreadsheet details.
