The provisions of PU Code Section 743 that require that the Commission continue to offer an interruptible program for heavy industrial customers and that the level of pricing incentives be maintained at the level in effect on June 10, 1996 will both statutorily expire on March 31, 2002. This rulemaking will serve as the forum to begin developing policies for the need, role, and structure of interruptible programs for all customer classes for this post-2002 period.
