San Ramon, Calif. – March 22, 2011 – The ZigBee® Alliance, a global ecosystem of organizations creating wireless solutions for use in energy management, residential, commercial and consumer applications, today announced that the current revisions of the ZigBee Smart Energy version 2.0 Technical Requirements Document (TRD) and Public Application Profile are available for public comment by the Smart Grid community at large. Public comments received last year for both documents, and Alliance responses, are also available for review. The Alliance continues its leadership role in expediting Smart Grid standards and is now accepting public comment on these revised documents for 30 days.

The Alliance received thousands of comments from around the world that were carefully reviewed and evaluated for inclusion in the updated documents. The revised documents reflect the work of many stakeholders in the industry, including product manufacturers, utilities, chip makers, meter manufacturers and numerous other Smart Grid leaders. The HomePlug Alliance, International Society of Automotive Engineers, SunSpec Alliance and Wi-Fi Alliance, among many others, made contributions to the proposed standard.

“The posting of these revised drafts of ZigBee Smart Energy 2.0 documents marks another significant milestone in the ongoing evolution of a standard for home area networks, advanced metering infrastructure and energy management,” said Bob Heile, chairman of the ZigBee Alliance. “The support received from the Smart Grid community was tremendous and the documents reflect contributions from numerous individuals and organizations worldwide. The ZigBee Alliance will continue driving development of the standard and will offer more public comment opportunities to ensure the most comprehensive standard with the broadest levels of support for energy management and efficiency in homes.”

Public comments on the ZigBee Smart Energy 2.0 TRD and Public Application Profile are accepted through online submission. All documents can be found at www.ZigBee.org/SmartEnergy. All comments must be received by April 26, 2011. The Alliance will announce future public comment periods based on the successful completion of development milestones.
