NERC Issues 2012 Interim Report on Geomagnetic Disturbances

On February 29, 2012, NERC released an interim report analyzing and making recommendations with respect to the effects of Geomagnetic Disturbances (GMD) on the Bulk Power System.  NERC conducted this assessment in response to findings in its High Impact, Low Frequency Event Risk to the North American Bulk System report issued in March 2010, which found that the best approach to high impact, low frequency events was through an organized combination of industry-led task forces and initiatives. 

The 150-page report found that a high impact, low frequency GMD event could lead to significant losses of reactive power, which could lead to voltage instability and, if not identified and managed appropriately, power system voltage collapse. The report offers short term and medium to long-term interim recommendations for NERC, including improvements to the tools used by system operators to manage GMD impacts and by industry planners to develop GMD mitigation strategies, increased education and information exchange, and a review of the need to enhance NERC reliability standards.  NERC also included a detailed work plan that it will follow in collaboration with EPRI.
