To foster market participant confidence the system operator contracted with PA Consulting, an international technology consulting group based in Los Angeles, to certify that the new billing and settlements system operates in strict compliance with NYISO’s market services and open access transmission tariffs for energy and ancillary services in its day-ahead and real-time markets. NYISO’s next focus area in its overall settlements cycle strategy is to enhance its invoice processing capability to enable invoicing on a basis more frequent than monthly. Shortening the invoicing cycle would not only improve market cash flow, but also overall market efficiency. Further, invoicing and clearing its markets more frequently than monthly would allow NYISO to reduce collateral required from certain market participants by as much as 70 percent. In February 2005, NYISO became the first wholesale market operator to co-optimize energy and ancillary markets at a five-minute level. In 2003, NYISO rolled out a data warehouse that provides market participants Web-based access to their settlement information within 36 hours of a trade day. The new billing and settlements system adds another success story to NYISO’s list of information technology innovations. Michael S.
