The Smart Grid: Re-powering America George W. Arnold National Coordinator for Smart Grid Interoperability NIST Gaithersburg, MD April 28, 2010

U.S. Electric Grid 2 Centralized, bulk generation Heavy reliance on CO 2 -producing coal, natural gas Limited automation Limited situational awareness Consumers lack data to manage energy usage One of the largest, most complex infrastructures ever built

A Key National Priority Fundamental Drivers Climate change Energy security Lifestyle dependent on electricity Jobs Smart Grid Goals Reduce energy use overall and increase grid efficiency Increase use of renewables (wind and solar don’t produce carbon) Support shift from oil to electric transportation Enhance reliability and security of the electric system 3

Energy Independence and Security Act Defines ten national policies for the Smart Grid: 1.Integrate digital technology to improve reliability, security, and efficiency 2.Dynamic grid optimization 3.Integrate distributed renewable resources 4.Demand response and demand-side energy- efficiency resources 5.Automate metering, grid operations and management 6.Integrate `smart' appliances and consumer devices 7.Electricity storage and plug-in electric vehicles 8.Provide consumers timely information and control 9.Interoperability standards for the grid and connected appliances and equipment 10.Lower barriers to adoption of smart grid technologies, practices, and services.
