In response to a mandate given by Congress and the Administration, NIST, through its Engineering Laboratory-led Smart Grid program and public-private Smart Grid Interoperability Panel (SGIP), is leading the coordination and acceleration of smart grid interoperability and security standards in collaboration with the private sector and has published the NIST Framework and Roadmap for Smart Grid Interoperability, which provides the foundation for future work. By utilizing expertise in NIST's Engineering, Physical Measurement and Information Technology Laboratories, this program will advance the measurement science that will increase asset utilization and efficiency, improve grid reliability, and enable greater use of renewable energy sources in the grid through research, standardization, testing and implementation of the NIST Framework.
