Status
A 10-day final ballot for TPL-007-2 - Transmission System Planned Performance for Geomagnetic Disturbance Events concluded at 8 p.m. Eastern, Monday, October 30, 2017The voting results can be accessed via the links below.  The standard will be submitted to the Board of Trustees for adoption and then filed with the appropriate regulatory authorities.
 
Background:
On September 22, 2016, FERC issued Order No. 830 approving Reliability Standard TPL-007-1 - Transmission System Planned Performance for Geomagnetic Disturbance Events. In the order, FERC directed NERC to develop certain modifications to the Standard, or to develop other new or revised Standards. The revisions include:
 
·        Modify the benchmark GMD event definition used for GMD Vulnerability Assessments;
·        Make related modifications to requirements pertaining to transformer thermal impact assessments;
·        Require collection of GMD-related data. NERC is directed to make data available; and
·        Require deadlines for Corrective Action Plans (CAPs) and GMD mitigating actions.
 
FERC established a deadline of 18 months from the effective date of Order No. 830 for completing the revisions, which is May 2018.
Standard Affected: TPL-007-1 - Transmission System Planned Performance for Geomagnetic Disturbance Events
Purpose/Industry Need:
Project 2013-03 will develop reliability standards to mitigate the risk of instability, uncontrolled separation, and Cascading as a result of geomagnetic disturbances (GMDs) through application of Operating Procedures and strategies that address potential impacts identified in a registered entity's assessment as directed in FERC Order 779 and FERC Order No. 830.
 
While the impacts of space weather are complex and depend on numerous factors, space weather has demonstrated the potential to effect the reliable operation of the Bulk-Power System. During a GMD event, geomagnetically-induced current (GIC) flow in transformers may cause half-cycle saturation, which can increase absorption of Reactive Power, generate harmonic currents, and cause transformer hot spot heating. Increased transformer Reactive Power absorption and harmonic currents associated with GMD events can also cause protection system Misoperation and loss of Reactive Power sources, the combination of which can lead to voltage collapse.
