2 Discussion Outline CERTS Introduction Research Drivers and Focus Changing Research Needs Transmission Grid Monitoring & Visualization Research Needs Evolving Research Needs Example of Phasor Technology Operational Consolidation and Wide-Area Reliability Visualization Solution for Reliability Coordinators -- Example Long Term Grid Research Framework Page 1

3 Consortium for Electric Reliability Technology Solutions (CERTS) CERTS was organized in 1999 as a partnership among universities, the private sector, and Department of Energy national labs. Consortium includes four labs (Lawrence Berkeley, Oak Ridge, Sandia, Pacific Northwest), Power Systems Engineering Research Center (consortium of 13 universities), and Electric Power Group. CERTS Industry Advisory Board includes ISOs, utilities, regulators, generators. CERTS research leverages public and private resources, including funding by the Department of Energy, Transmission Reliability Program, and the California Energy Commission Public Interest Energy Research Program. CERTS research is focused on addressing gaps in tools, technologies, systems, market rules, and management processes needed to manage the reliability of the electric grid and efficient market operations.
