摘要: The massive electric power blackout in the northeastern United States and Canada on August 14-15, 2003 resulted U.S. electricity system being called ''antiquated'' catalyzed discussions about modernizing grid. Industry sources suggested that investments of $50 to $100 billion would be needed. This report seeks quantify an important piece information has been missing from these discussions: how much do interruptions fluctuations quality (power-quality events) cost consumers? Accurately estimating this will help assess potential benefits improving reliability We develop a comprehensive end-use framework for assessing consumers power-quality events (referred collectively as ''reliability events''). expresses costs function of: (1) Number customers by type region; (2) Frequency experienced annually (including both customers; (3) Cost events; (4) Vulnerability events. is designed so its estimate can improved additional data become available. Using our framework, we national $80 annually, based best available public domain. However, there are large gaps significant uncertainties currently Notably, were not able Sensitivity analysis some suggests total annual could range less than $30 more $130 billion. Because enormous decisions may estimate, encourage policy makers, regulators, industry jointly under take comparatively modest-cost improvements needed used Specific areas improvement include: coordinated, nationwide collection updated consistent definition recording duration frequency events, including efforts reduce their vulnerability
