Background

Status:	Approved
Date Posted:	Sep 14, 2006
Sponsor:	ERCOT Staff
Urgent:	No
Sections:	7.2, 7.5.2.1, 7.5.3.1, 7.8
Description:	Revise how CRRs may be traded in the bilateral market and in CRR Auctions. This revision would limit CRR trading to time-of-use blocks for a particular date and CRR Offers in CRR Auctions to time-of-use blocks. With this revision, CRR Account Holders would not be able to trade a particular hour or a block of hours that is not one of the defined time-of-use blocks in Section 7.3 (6).
Reason:	The vendor (Nexant) CRR system does not support the flexibility of bilaterally trading CRRs for each hour and offering CRRs for particular hour or hours (except time-of-use blocks in Section 7.3 (6)) in CRR Auctions. Vendor estimates a cost of $395,000 for adding this flexibility to their system due to required fundamental changes in the following: data interfaces; Market User Interface functionality (new Java based editor, bilateral trading system, portfolio editor, downloads): Market Operator Interface functionality (command manager); Database Subsystem; testing; and documentation. In addition to the development costs, the CRR team believes there might be other long-term costs associated with the maintenance of the CRR System due to increased complexity, possible need for increased H/W costs for performance and storage, increased auditing overhead, archiving requirements, etc. These long-term costs are not very easy to assess and have not yet been quantified.
