RTCTF,

ERCOT has posted the updated Key Principle documents with revisions for the
next meeting on Sep 19th

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)-

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 1.3 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).
