"As directed by the Energy Independence and Security Act (EISA) of 2007 (P.L. 110-140), the National Institute of Standards and Technology (NIST) is coordinating an effort to develop a common framework and interoperability standards for the smart grid. The purpose of this hearing is to examine the progress of this effort and discuss how standards affect the development of the smart grid and the deployment of smart grid technologies. Additionally, witnesses will discuss current and anticipated challenges associated with these standards and offer their views on the ability of the current process to meet these challenges and develop standards that will enable the growth of a reliable, efficient, and secure smart grid ... The term "smart grid" refers to modernization of the electric grid to incorporate digital computing, microprocessor-based measurement and control, and communication technology. These technologies will enable greater two-way communication between consumers and electricity providers so that consumers can adjust their electricity usage in response to real-time demand and price information. These technologies will also enable two-way energy transfer ... and will help accommodate widespread use of different types of electricity generation and storage options."--P. 3.
