Market Manipulation Procedures Extended in New York ISO

LCG, May 2, 2002--The Federal Energy Regulatory Commission is keeping in place procedures in the New York Independent System Operator territory that are intended to prevent market abuse through the end of May.

The programs were to have ended at the end of April, but were extended in order to provide a smooth transition to a possible new set of market rules. The federal agency is currently reviewing the ISO's own wholesale market mitigation plan, submitted approximately one month ago.

Representatives of generation owners, such as the Independent Power Producers of New York, have expressed dissatisfaction with the rules, which include automatic lowering of bids when they are found to deviate from historical patterns of market behavior.

The ISO's plan would provide for lenient treatment of new generators with respect to market abuse rules, at least initially. It is hoped that this would encourage investment in new generation. At the same time, its plan includes restrictions to deter market abuse thought to be more strict than the existing market regime.
