The Western Interconnection Synchrophasor Program (WISP) began as a collaborative project to improve reliability of the Bulk Electric System (BES) in the Western Interconnection.
Between 2010 and March 2014, WISP installed more than 480 new or upgraded phasor measurement units (PMUs) in the Western Interconnection. PMUs deliver high-speed, synchronized measurements using a secure communications network and software in order to better manage the power grid. Today, system operators can visualize power system disturbances, and minimize the risk of these disturbances from evolving into a major, system-wide event on the BES.
Peak Reliability continues to play an important role in the program by housing the PMU registry, the historical data archives, disturbance reports, next-day studies, and the wide-area view.
