Joint development and consistent bulk transmission outage reporting and analysis procedures by two NERC regions

Two North American Electric Reliability Council (NERC) regions, the Mid-Continent Area Power Pool and the Mid-America Interconnected Network, have individually collected bulk transmission outage data for a number of years. Based on recent research work, the members of the two regions realized that related multiple outages significantly affect bulk transmission system reliability. However, no existing data collection methods provided sufficient data to report and analyze adequately relationships between multiple outages. The experiences of these NERC regions working together to derive a consistent bulk transmission performance analysis package are discussed. The resultant data collection philosophy and format and the expected analysis capability are reviewed. Potential benefits of standardizing data formats and definitions are presented
