The NIST Role

Energy Independence and Security Act (EISA) of 2007

Title XIII, Section 1305.

Smart Grid Interoperability Framework

In cooperation with the DoE and other stakeholders, NIST has “primary responsibility to coordinate development of a framework that includes protocols and model standards for information management to achieve interoperability of smart grid devices and systems…”


  • Smart Grid Interoperability Panel

  • NIST Framework and Roadmap for Smart Grid Interoperability Standards

    • Priority Action Plan for IP – PAP#1

    • Priority Action Plan for Wireless Communications – PAP#2

    • Application communication requirements

NIST Three Phase Plan


Engage stakeholders in a participatory public process to identify applicable standards, gaps in currently available standards and priorities for new standardization activities


Establish a formal standards panel to drive longer-term progress.

Public review

and comments


Develop and implement a framework for testing and certification

(Draft) Framework and Roadmap for Smart Grid Interoperability Standards ( Release 1.0)

(Final) Framework and Roadmap for Smart Grid Interoperability Standards ( Release 1.0)






Smart Grid Interoperability Panel (SGIP) Vision

  • Public-private partnership to support NIST EISA responsibility

  • Open, transparent body

  • Representation from all smart grid stakeholder groups

  • Open to any materially interested stakeholder organizations

  • Not dominated by any one group

  • SGIP does not directly develop or write standards

    • Stakeholders participate in the ongoing coordination, acceleration and harmonization of standards development. 

    • Reviews use cases, identifies requirements, coordinates conformance testing, and proposes action plans for achieving these goals.

SGIP: Governing Board Vision

  • Maintains a broad perspective of the NIST Interoperability Framework and supports NIST

  • Provides guidance and tools that make it an impartial and practical resource for SG stakeholders

  • Members representing a broad community based on breadth of experience and involvement

    • Each stakeholder category has a position on Governing Board

    • Additional at-large and ex-officio members

    • Nominating committee process in steady state

  • Consensus is a core value

    • All legitimate views and proposals are considered

    • Voting mechanisms to be defined


First Phase Initial Output: NIST Framework and Roadmap for Smart Grid Interoperability Standards, Release 1.0

  • A conceptual reference model to facilitate design of an architecture for the Smart Grid overall and for each of its networked domains;

  • An initial set of standards;

  • Priorities for additional standards necessary to resolve important gaps and to assure the interoperability, reliability, and security of Smart Grid components; and

  • Action plans for responding to short-term and long-term needs for standards, including recommended timetables and identification of necessary collaborative relationships with standards development organizations (SDOs) with expertise in Smart Grid domains or technology areas

Level of urgency

The $3.4 billion in U.S. Smart Grid Investment Grants, combined with matching $4.7 billion in private funds ($8.1 billion total) will result in deployment, over the next 3-4 years of

40 million smart meters (about 1/4 of the total meter base in the U.S.)

850 phasor measurement units covering 100% of the grid

200,000 smart transformers

700 automated substations

1 million in-home displays

170,000 smart thermostats

175,000 other load control devices.

There is only a very small window of opportunity to specify the standards that will be used in these deployments since they will be completed within 3-4 years.

Smart Grid cyber security strategy


  • Cyber Security Coordination Task Group (CSCTG) to develop a set of recommended cyber security requirements


  • Draft NIST Interagency Report (NISTIR) 7628, Smart Grid Cyber Security Strategy and Requirements

    • Comments must be received on or before December 1, 2009

    • How to provide comments:


    • Final document planned for publication in March 2010.

Issue: Role of Internet Protocol(s) in the Smart Grid

  • The Smart Grid will use a variety of different networking environments across different smart grid domains and sub-domains

  • Given its predominance and ubiquity, the Internet technology (IP) is a key networking technology to consider in the context of the Smart Grid

  • A number of challenges remain to be addressed due to the requirements imposed by many Smart Grid environments and applications:

    • What suite of IP protocols are applicable for specific Smart Grid applications?

    • What suite of IP protocols should be used for network control? management? security?

    • Are there any gaps with existing protocols?

    • Should new protocols/extensions be developed?

IP PAP#1: Guidelines for the use of IP protocol suite in the Smart Grid

  • Develop Smart Grid application communication requirements and devise a taxonomy for applications with similar network requirements

    • Draft matrix under development and available for review http://collaborate.nist.gov/twiki-sggrid/pub/SmartGrid/PAP02Wireless/app_matrix_pap.xls

  • Identify a Core Protocol Suite for IP-based Smart Grid

    • IETF drafts and reports submitted for considerations


  • Develop Application-Specific Protocol Requirements

    • Identify additional protocols or protocol enhancements beyond the core suite required by a specific class of applications

    • Develop guidelines for IP-based Smart Grid networks

  • Perform Gap Analysis

    • Identify new protocol or protocol enhancement standardization activities required to fully support the Smart Grid Vision


Issue: Use of wireless communications in the Smart Grid

  • There are a number of advantages for using wireless communications including:

    • Untethered access to information

    • Mobility

    • Interoperability

    • Reduced cost and complexity

    • Availability of technologies with different characteristics to choose from

  • A number of challenges remain to be addressed:

    • How to choose among technologies with different characteristics?

    • How do we know which technology to use for what Smart Grid application?

    • Are there any implications for using a certain wireless technology in a certain environment?

    • Are there any deployment? Interference issues?

Wireless PAP#2 Guidelines for the use of wireless communications in the Smart Grid

  • Develop Smart Grid application communication requirements and devise a taxonomy for applications with similar network requirements

    • Draft under development and available for reviewhttp://collaborate.nist.gov/twiki-sggrid/pub/SmartGrid/PAP02Wireless/app_matrix_pap.xls

  • Develop terminology and definitions

  • Create an attribute list and performance metrics for wireless standards

    • Draft developed and available for reviewhttp://collaborate.nist.gov/twiki-sggrid/pub/SmartGrid/PAP02Wireless/NIST_PAP2-_Wireless_Characteristics-IEEE802-v_02.xls

  • Create an inventory of wireless technologies and standards that are identified by each SDO

    • Feedback is expected by December 6, 2009.

  • Conduct an evaluation of the wireless technologies based on the application requirements

  • Perform a gap analysis and developing guidelines for the use of wireless technologies.


Approach for developing application communication requirements

  • Develop a set of characteristics to capture the application communication

    • How much data is being exchanged?

    • How often is the data being exchanged?

    • How much delay can data delivery incur?

    • Who are the recipients of the data?

  • List a representative set of Smart Grid applications

    • Identify different applications or applications with different characteristics

    • Applications belonging to a different Smart Grid domain are not necessarily different from this stand point

  • Place characteristics and application types on a two dimensional matrix where columns represent the characteristics and rows represent application types

  • Devise a taxonomy for applications with similar network requirements

  • Fill out matrix entries


Progress to date on developing application communication requirements

  • Reviewed many Smart Grid use cases, reports, white papers

  • Reviewed FCC NOI filings on the implementation of Smart Grid technology

    • http://www.fcc.gov/Daily_Releases/Daily_Business/2009/db0904/DA-09-2017A1.txt

  • Developed a draft in cooperation with utility groups, Open SG, SG stakeholders, interested parties

  • Posted draft for review on twiki and on PAP mailing lists

    • http://collaborate.nist.gov/twiki-sggrid/pub/SmartGrid/PAP02Wireless/app_matrix_pap.xls


Seeking input on the application communication requirements

  • Related to the application characteristics – or columns in the matrix:

    • Do you have any comments on the columns capturing the characteristics? Are there any missing columns?

  • Related to the application types – or rows in the matrix:

    • Are the rows representative of the Smart Grid space and domains? Are there any missing applications?

  • Related to the quantitative requirements – or matrix entries:

    • Do you have any numbers, aware of any numbers, reports that contain numbers?
