NYISO accomplished this long-standing goal in August 2007 with the implementation of its settlement system replacement project, a software release with a specialized settlements rules engine that allows NYISO to process a daily settlement run in about 30 minutes. NYISO’s previous billing and settlement system would take up to two hours or longer to complete a daily settlement run, leaving little time to identify data anomalies and process same-day re-settlements.

NYISO’s new billing and settlements system goes a long way in meeting these two milestones by providing the architectural framework and computing power to process settlements on a near real-time basis as well as building stakeholder confidence that settlement results comply with NYISO-administered tariffs. “The speed and accuracy of NYISO’s new billing and settlement system is one of the fastest settlements engines in use among ISOs nationwide,” said Randy Bowers, NYISO principal settlements, process and controls. we were able to deliver the product on schedule utilizing “The system allows NYISO to process same-day rea rules-based calculation engine, cutting-edge technolsettlements and to take the next step toward its ultimate ogy that all ISOs are striving for, makes the deployment settlements goal — to calculate settlements in near real even more impressive.” time,” Bowers said. The successful implementation of NYISO’s new billing “ISOs have always struggled with the data-intensive, and settlements system certainly shows how far NYISO highly complicated problem of calculating settlements,” has come since 1999, when its settlement system often explained Rich Dewey, director of NYISO product took as long as eight to nine hours to produce a daily and project management. “The New York settlements settlement. “There were days back in the early going problem is more intricate than other ISOs.
