The National Institute of Standards and Technology (NIST) has published its NIST Framework and Roadmap for Smart Grid Interoperability Standards, Release 3.0, a document that reflects advances in smart grid technologies and developments from NIST's collaborative work with industry stakeholders. Revisions to its guidelines for smart grid cybersecurity are available as well.
The 3.0 framework updates the plan for transforming the nation's aging electric power system into an interoperable smart grid—a network that will integrate information and communication technologies with the power-delivery infrastructure, enabling two-way flows of energy and communications. The Energy Independence and Security Act of 2007 established a goal to modernize the nation's electricity system and assigned to NIST the primary responsibility to coordinate development of a framework to achieve interoperability of smart grid devices and systems.
The document first appeared in January 2010 and was last updated in February 2012 to its 2.0 version. The 3.0 version was needed in part because of recent progress in grid modernization, including the following developments:
The document incorporates public responses to the 3.0 framework's draft version, collected during the official comment period earlier this year. The framework 3.0 document is available at www.nist.gov/smartgrid/upload/NIST-SP-1108r3.pdf.
NIST also has published a revision to its Guidelines for Smart Grid Cybersecurity (NISTIR 7628), the original version of which appeared in 2010. NISTIR 7628 Rev. 1 updates include new sections describing the relationship of smart grid cybersecurity to the NIST Cybersecurity Framework, cyber-physical attacks, cybersecurity testing and certification, and address regulatory changes involving privacy.
