  2. Overview • Overview of EIPP • Discussion of Entergy Phasor System • Real-Time Demonstration of Entergy Phasor System • http://phasors.pnl.gov

  3. Strategic Importance August 14th Blackout By-The-Numbers 1Canadian Province 3deaths 8U.S. states 12airports closed 23 cases of looting in Ottawa 250+power plants 9,266square miles 61,800MW of power lost 1.5 mill Cleveland residents without water 50 millionpeople $4.5-10 billionin economic activity lost “…it's clear that the power grid needs an overhaul. It needs to be modernized. As we go into an exciting new period of American history, we want the most modern electricity grid for our people… we need more investment; we need research and development…” President Bush September 2003 “When the lights go out, modern life as we know it grinds to a sudden halt. Transportation is interrupted, communications fail, water systems shut down, factory work is disrupted, food spoils, businesses lose money, and people are inconvenienced and even endangered. ” Secretary Abraham April 2004

  4. EIPP Working Group • Vision – improve power system reliability through wide-area measurement, monitoring and control • EIPP Working Group Organizations (as of 12/2004) US DOE Entergy National Grid* AEP FERC NERC Ameren First Energy NYISO CERTS Hydro One NYPA Com Ed* IMO* PJM Con Ed* ISO – NE Southern Co. Dominion MAPP SPP Duke* MISO TVA at least ten additional Work Group members are vendors of hardware or software * These organizations have expressed interest but have not yet committed resources.

  8. Eastern Interconnection Phasor Project Plan Phase I (Completed 12/04) • 20 Instruments installed • Resolve major communications issues • Transfer software tools to users • Establish relationships EIPP Phase II (2007- ) • More than 350 Instruments • Situational awareness and state estimator app’s realized, automatic control app’s beginning • Vendors participating at all levels • Inexpensive instruments and communications available Phase II (2006) • ~50 Instruments • Situational awareness and state estimator app’s demonstrated • All major corridors covered • Data available to research community to begin work on projected benefits

  9. Expected Benefits from EIPP Project • Improved wide area visibility • Improved real time monitoring tools for reliability coordinators and system operators • Improved ability to monitor grid dynamics and stability for reliability management • Time-synchronized data for system assessments and post disturbance analysis • Improvements in state estimation • Dynamic system ratings for improved reliability and market performance • Public-private industry collaboration to develop new technologies and systems for modernizing the electric grid
