Frequency control has been an on-going issue and concern with Market Participants and ERCOT. PRR 356 (SCE Performance Requirement) and PRR 358 (Negative Impact Schedule Control Error) were submitted, respectively, in August and September of 2002 with the intent of providing incentives to QSEs to more closely follow SCE, thereby resulting in improved frequency control and reliability. These two PRRs have been languishing for nearly two years, with no resolution expected.
