As part of its mission to promote reliability excellence and serve as a leading reliability resource, the North American Electric Reliability Corp. published two reports to help inform industry and policy makers on trends, challenges and recommendations for ensuring the reliability of the bulk power system. The 2013 State of Reliability provides an integrated view of reliability performance, and the 2013 Summer Reliability Assessment identifies common themes or challenges across North America for the upcoming summer.
"These assessments of performance and anticipated seasonal conditions are an integral part of delivering on NERC's mission to ensure bulk system reliability for North America," said Thomas Burgess, vice president and director of Reliability Assessment and Performance Analysis. "The reports provide a sound, technical base for insights and guidance that enables industry and policy makers to take effective steps and make sound decisions supporting reliability."
The State of Reliability delivers analytical information from a number of reliability indicators on trends and reliability risks that can be used for project prioritization, process improvement and risk identification. This year's report reflects continuing steady overall reliability performance, with some indicators of improving trends between 2008-2012. The key findings include:
Bulk power system reliability remains adequate. The number of bulk power system transmission-related events since 2008 resulting in loss of firm load decreased from an average of nine per year to two in 2012.
