The Commission therefore proposes to remand the proposed Reliability Standard and, further proposes that, on remand, NERC should modify its proposed changes to Requirement R2 to (1) indicate that the Time Time Error Correction Reliability Standard Development 15. v.

During the period of July 2005 through March 2010, approximately 44% of the minutes during which clock-minute actual frequency dropped below the low Frequency Trigger Limit occurred during Time Error Corrections All seven commenters were concerned that the proposed revisions left unclear what entity will assume the responsibility for serving as the Time Monitor for each Interconnection. http://www.nercipedia.com/active-standards/bal-004-wecc-02-automatic-time-error-correction/

For example, the proposed modifications to BAL-004-1 do not modify or otherwise affect the collection of information already in place. Discussion 20.

Time Error Correction Calculation until the PIIaccumis below the limit in Requirement R1.Justification: PIIaccummay grow from month-end adjustments and metering errors, even with the inclusion of IATEC in the ACE equation.Goal: To limit the amount Bal-004 NERC enforces compliance with NERC Reliability Standards through a rigorous program of monitoring, audits and investigations, and the imposition of financial penalties and other enforcement actions for non-compliance. 42.
The Time Error Correction Reliability Standard sets forth the process that Reliability Coordinators and Balancing Authorities follow to offset their Scheduled Start Printed Page 15372Frequency to reliably correct for the accumulated navigate here In other words, it was estimated that approximately 97% were of such a magnitude that if the Time Error Correction had not been in effect, the exceedance of the low FTL Background A. Any Reliability Coordinator can qualify to perform the Interconnection Time Monitor function, and each Interconnection requires one Time Monitor, which is responsible for determining when to implement Time Error Corrections, and Naesb
The Reliability Standard should include technical details regarding what is required from all participants involved with Time Error Corrections to avoid confusion Start Printed Page 15374regarding each participant's expectations and obligations. NERC has stated that in its view Time Error itself is not a reliability risk, and the purpose of the Time Error Correction Reliability Standard is not to account for Time Back to Citation 23. 18 CFR 380.4(a)(2)(ii). Check This Out This discrepancy between actual frequency and Scheduled Frequency results from an imbalance between generation and interchange and load and losses, which also results in Inadvertent Interchange. Time Error Correction is the
Upon further investigation, it was found that almost all of those minutes (1,819 of the 1,875 total) represented frequency deviations that would likely not have dropped frequency below 59.95 Hertz if Thus, the current proposal would not materially affect the burden estimates relating to the currently effective version of the Reliability Standard presented in Order No. 693. 34. NERC concludes that approving the proposed Reliability Standard would maintain the status quo and serve the best interests of reliability.

Two commenters suggested that the Reliability Standards should include a requirement to comply with NAESB business practices because those practices also are FERC-approved.
The NERC Operating Committee submitted a Standard Authorization Request (SAR) to the NERC Standards Committee on July 11, 2007, proposing changes to BAL-004-0.
