IEEE has several smart-grid standards ready and in the works.

IEEE 1901
Completed: September 2010
The IEEE Standard for Broadband over Power Line Networks: Medium Access Control and Physical Layer Specifications deals with high-speed communication devices—called broadband-over-power-line (BPL) devices—that operate over electric power lines. The standard specifies transmission frequencies below 100 megahertz and applies to all BPL devices. The standard also defines mechanisms for interoperability between different BPL devices and explains how to ensure the desired bandwidth and quality of service. It also addresses security issues, including the privacy of communications between users and security-sensitive services.

Expected completion: September 2011
IEEE Draft Standard for Synchrophasor Measurements for Power Systems defines the frequency of synchronized phasors, or synchrophasors, and the rate of change of frequency measurements. It also describes time tag and synchronization requirements.

Expected completion: December 2011
The IEEE Draft Guide for Smart Grid Interoperability of Energy Technology and Information Technology Operation With the Electric Power System and End-Use Applications and Loads includes the criteria for functional performance and evaluation, the engineering principles used for interoperability, and terminology. It also covers best practices for the smart grid.

Expected completion: March 2012
The IEEE Draft Standard for Low Frequency [less than 500 kilohertz] Narrow Band Power Line Communications for Smart Grid Applications specifies communications between low-frequency devices operating over AC and DC power lines. Coexistence is assured with BPL devices by minimizing out-of-band emissions in frequencies greater than 500 kHz. It addresses how the grid will communicate with utility meters, electric vehicles at charging stations, and home networks. Lighting and solar panel power-line communications are also covered.

Expected completion: July 2012
The IEEE Draft Standard for Synchrophasor Data Transfer for Power Systems defines a method for the exchange of synchrophasor measurement data by power-systems equipment. It specifies the types and uses of real-time communications between phasor measurement units, phasor data concentrators, and other applications, as well as content and data formats.

Expected completion: July 2012
IEEE Draft Standard Profile for Use of IEEE 1588 Precision Time Protocol in Power System Applications specifies a common profile for using IEEE 1588-2008 in power-system protection, control, automation, and data-communications applications over Ethernet. The profile specifies the preferred physical layer (Ethernet), higher-level protocols used for precision time protocol messages, and configuration parameters.

Expected completion: December 2012
The IEEE Draft Recommended Practice for Establishing Methods and Procedures that Provide Supplemental Support for Implementation Strategies for Expanded Use of IEEE 1547 outlines methods that can increase the usefulness of that standard. IEEE P1547.8 also deals with interconnecting distributed resources and electric power systems.
