Defense Plans against Extreme Contingencies
Since the shock of the 1965 North American blackout, other multi-million-dollar blackouts have continued to occur throughout the world. Though each event is analyzed carefully, and targeted corrective actions are identified, additional comprehensive system-wide measures are still needed to protect against severe unforeseen fast-developing cascading events. The CIGRE Technical Brochure C2.02.24 provides a roadmap for the development of defense plans to mitigate extreme contingencies with the intent to lead power system professionals to improve electric system reliability and security of the grid. The basic premise for protection against extreme contingencies is that a failure in one area of the grid should not result in blackouts elsewhere, and that such situations could be minimized by well designed, maintained, operated and coordinated power grids.

The North American Synchro-Phasor Initiative (NASPI)
The North American SynchroPhasor Initiative (NASPI) is a joint effort between the U.S. Department of Energy (DOE) and the North American Electric Reliability Corporation (NERC). The goal is to improve power system reliability through wide-area measurement, monitoring and control. This will be achieved by facilitating a robust, widely available and secure synchronized data measurement infrastructure for the interconnected North American electric power system. It also includes associated analysis and monitoring tools for better planning and operation, and improved reliability. This article provides an overview of NASPI, including recent accomplishments, current status, and planned activities. More
