The blackout that impacted the U.S. and Canada on August 14, 2003, was notable for its extent, complexity, and impact. It triggered a massive review of operating records to determine what happened, why it happened, and how to avoid it in future operations. Much of this work was done at NERC level, through the U.S.-Canada Power System Outage Task Force. Additional background information concerning the event was gathered together by a group of utilities that, collectively, have been developing a wide area measurement system (WAMS) for the eastern interconnection. Like its counterpart in the western interconnection, "WAMS East" has a primary backbone of synchronized phasor measurements that are continuously recorded at central locations. Operational data have been critical for understanding and responding to the August 14 Blackout. Records collected on WAMS East demonstrate the contributions that well synchronized data offer in such efforts, and the value of strategically located continuous recording systems to facilitate their integration. This paper examines overall performance of the WAMS East backbone, with a brief assessment of the technology involved.
