The Western Interconnection Synchrophasor Program (WISP ) Update Vickie VanZandt Joint Synchronized Information Subcommittee Salt Lake City August 10, 2010

Program overview recap WISP is an interconnection-wide synchrophasor system expected to enable smart grid functionality. WISP will deploy: Upgraded or replacement Phasor Measurement Units (PMUs); New PMUs; Phasor Data Concentrators (PDCs) and SuperPDCs; Historical data archival systems at WECC RCs; and Wide area data network to connect measurement devices. 2

Program overview recap (cont.) Real-time and off-line applications for: Situation awareness for operators and reliability coordinators; Event and system performance analysis for operations and planning engineers; Model validation and improvement; Real-time control and protection – including wide-area controls; and System restoration. Funding: $54M from DOE and $54M from WISP Partner Entities. 3
