## Abstract

Pursuant to section 215 of the Federal Power Act (FPA), the Federal Energy Regulatory Commission (Commission) approves regional Reliability Standard BAL-004-WECC-01 (Automatic Time Error Correction), as submitted by the North American Electric Reliability Corporation. As a separate action, pursuant to section 215(d)(5) of the FPA, the Commission directs the Western Electricity Coordinating Council to develop several modifications to the regional Reliability Standard. The regional Reliability Standard requires balancing authorities within the Western Interconnection to maintain interconnection frequency within a predefined frequency profile and ensure that time error corrections are effectively conducted in a manner that does not adversely affect the reliability of the Interconnection.
