NPRR #28 · Revision Request
NPRR028 CRR Trading in Blocks Only
ReasonThe 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.
