Background
The SAR states that the current definition of Reporting Area Control Error (ACE) presents a conflict with the Western Interconnection's Automatic Time Error Correction (ATEC) process and does not allow other Interconnections to pursue ATEC. Additionally, there is confusion in that the terms ACE and Reporting ACE are both used throughout the standards. A revised definition should provide improve long-term average frequency performance as well as give other Interconnections the ability to pursue automatic correction approaches.

Standard(s) Affected: Multiple standards reference the Reporting ACE definition, including BAL.
